Excellent video!
Thank you! Hope it helps!
Cool video, can you please show how you connected this same module you are reprogramming? Thx!
Hi, can I bench program a gen4 E38 ecm? I have all the needed tools (J2534, TDS license, etc) but I´ve never tried on a bech. It´s an LS swap platform (2010 Camaro SS donor) that needs an ECM replacement. I don´t have any other modules of the donor vehicle. TIA.
I have a question on this. I have a 2020 corvette I’m rebuilding that was wrecked. Previous owner installed a used rack and pinion that will need programmed. Is this able to program the used rack into my ECU?
I know its an old video but how about the k33 module for the hvac system
Can you show a video how to compare tcm vs junkyard unit... ie for vin swap also.. ie if you need configure a 4x4 transfer case on to non 4x4 tcm configuration...
This process does all the programming based on the vehicles VIN number. With some modules you have multiple calibrations to choose from during the reflash process. These calibrations are usually related to the RPO codes. You may be able to choose the RPO for 4x4 in your case but I have never tried to do a 4x4 swap so I'm not positive on that.
As far as the VIN swap goes. At the beginning of the process when the SPS2 software starts up you goes through the vehicle identification. This is where you enter the VIN number. The VIN you enter here, or that the software reads from the PCM, is the VIN that will be used through the reflash process. If a used module is installed the software will wipe the VIN and program in the new VIN.
I wish I could program newer modules to my trucks vin. Gonna swap the 03+ modules into my 02
Yes gm, and all other manufacturers, only allows you to program using the vin of your vehicle. If the 03+ module is the same part number it would be able to be programmed
Can I program 6T45 TCM ON BENCH MODE WIL WORK IF I CONECT MY INTERFACE STRAIGHT TO TCM LET ME KNOW THAO
Will this work to reprogram sensors for 2015+ Yukons, Suburbans, and Escalades? I need some drivers assist sensors programmed.
Yes. This is the manufacturer method for reprogramming modules on all GM brands
Will work on Body Control Module to can activate the cruise control? My truck was coming without cruise control from manufacturer.
In some cases this can be done. On GM vehicles you often select the option codes that the vehicle has during the programming procedure and this would be where you select the RPO Code for cruise control. This is not on all gm vehicles though. Some just do the programming based on the VIN.
So I can get a junkyard ECU and program to a different car?
In many cases yes, but some vehicles do not allow it. Unfortunately I have not ever found a good info source for which vehicles allow you do program used modules.
Can someone explain the locksmith license into more detail and if required to get? I am just starting into this career path and I have much to learn, excellent video!
The locksmith license is called an LSID. It is required when doing programming with vehicle security system items. Typically the shop has the license not the tech as it is somewhat expensive.
@@apmotorsports5568 thank you much appreciate! is it possible for a video on how to go further or a way to contact you for further detail? as the shop I’m at right now does not have one we are barely getting introduced to this side of the business
I will have to look into making a video on it. I will get back to you in a little bit with the website for it though, the company is NASTF. basically you fill out an application with then, give them the business info, business license, and insurance info and pay their fee then they will process it all. It can take awhile for the processing to get done.
@@apmotorsports5568 Thank you so much really appreciate it
sdrm.nastfsecurityregistry.org/dotorg/landing
Thus is the website you need to register with. Once your registered there is videos on the site to help you figure out gow to do everything. Basically when you are programming a vehicle the programming software, or the manufacturer website, will ask for your LSID info. Anytime you need to that, you then have to log into the NASTF site and fill put a form that essentially is just a record of why you are accessing the vehicle security system. If the forms are not filled out your LSID will be temporarily locked until the forms are correctly filled out. This process is also for for things like Chryselr Key Codes. Its confusing the first few times you need to do it but not bad once you are used to it.
But can you add a module, like let’s say a VPM, and program it to work within the vehicle network?
This is meant more for vehicles as they were originally sold. As far as adding modules, sometimes that can be done but sometimes it can confuse the software as it goes by the vin number. I do not have alot of experience with that.
Hey sir, if I am working on a 2004 Chevy Colorado that has a salvaged motor and new ecm... and I don't know the vin of the engine's origin... you got any advice?
You use the vin for the vehicle the engine went into. The vin of the motor orginal vehicle doesn't matter.
@@apmotorsports5568 Thanks... this sounds like a pretty good odds to get this thing running! I need a CarDaq+3, a charger made for re'flashing, and an SPS2 subscription from AcdelcoTds?

I won to swap ecu of Chevrolet Cruze I use the im508, launch v, xtool x100pad2 process but still the key light is still there please any idea
GMC terrain, Chevrolet Cruze the same 2014 old ecu damage and I need to swap new ecu any ideas
Did you do the security relearn? In some cases you need to relearn the security system after replacing a module. On some GM vehicles you can do what's called a "30 minute Relearn." I do not believe thus works on a Cruze though. You likely will need to use the TIS2WEB system to relearn the security. This will require you to have an LSID before GM will give you access to security functions.
I am not familiar with the specific tools you are using but the reflash process is the same regardless of the J2534 device you use.
I feel your pain. Did you find a solution?
How to flash new side detection module on the right side if only option we have for the lh side only?
What is the year/make/model? If I remember correctly in some cases only 1 of them gets flashed and the runs through the 1 that gets flashed. They act kind of like a master/slave type system. I can do a little research and let you know for sure if you can provide the vehicle info.
@@apmotorsports5568 2015 GMC Yukon. I get through flashing on lh side module, but still states that not programmed.
Okay, I will do a little reading but from my experience, if the module is not in the list when choosing which module you want to program then you need to use the scan tool to configure the module not reflash it. I will do a little research to see of that may be the case for you here.
I did a little more reading and according to the info I can find, the system is a master/slave style system as I described. In this case the left object sensing module is the master and has a direct communication line with the right side module. The left module is in complete control of the right and can set codes for both modules. There is no way for you to talk with the right side module usinh a scan tool as you are actually talking with the left module. In this case I would recommend that you check your wiring between the left and right modules, of the wiring all checks put good then there is a good chance the left side module has a problem. It's also possible that your new right side module is bad, new doesn't always mean good unfortunately.
So all I need is to click under immobilizer learn and I assume it'll ask me to enter my LSID?
With gm you access the immobilizer by selecting it as a module. When you select a module to reprogram the immobilizer is one of the module options. The process is a little strange as it will make you wait for 10 minutes and then tell you the reflash has completed but not instruct you to put in the key and turn it as the instructions tell you. I believe it asks you for your lsid info when you start that reflash process.
Do you need a license to get programming files if so could you make a video about it. Been searching and I see a yes and no depending what you are reprogramming
The only time you need a special license for any reprogramming is when programming the security system with some manufactures. The license is known as an LSID and you apply for it with a company called NASTF. Go to, sdrm.nastfsecurityregistry.org/dotorg/landing, and apply for the SDRM Credential. In order to be able to do this you need to be a business and provide them with business licenses, insurance info, and a few other things. Again this is only an issue when doing things with the security systems.
Will this set up work to make changes to a bcm in a 2015 gmc 2500? My truck was from Canada and the headlights cannot be shut off with the vehicle in drive. I need to be able to shut them off going through a security gate at my work.
With many vehicles there are BCM options that can be set during the BCM Setup Procdure. I'm not sure what settings can be changed on that truck specifically. A factory level scan tool can also change someone theose settings I'm many cases. You may also be able to turn off your lights by very slightly applying the parking brake. Having the parking brake slightly applied, 1 click at most, will typically turn off the DRL system on GM vehicles
@@apmotorsports5568 I tried the parking break trick but had no luck, I also talked to the dealerships near me and they won't change the setting for me. I've been doing research and it looks like there are a few options using a vcx nano and sps
I'm not sure about the vcx but to use SPS you any J2534 device and a gm subscription will work
@@apmotorsports5568 good to know because I've been looking at the different options of j2534 devices and vcx nano seems a little sketchy compared to some others!
Personally I always recommend the Drew Technologies products. If you are only looking to use it for GM Vehicles they have a line called Mongoose Cables that are designed for a specific manufacturer. Last time I checked ot was about $50 for one of those, I'm not sure if they have a GM one though. The J2534 device will also allow you to use the gm factory scan tool software of you purchase the subscription for the software.
Does this GM software allow you to turn off features within a module? For example, disabling mag ride?
In some cases when reflashing a module there are certain options that it has you choose from so the module knows what the vehicle is equipped with, but it doesn't exactly let you turn features on and off. Some features can be turned on and off just using a capable scan tool as well.
@@apmotorsports5568 thanks. I’ve been on the hunt for any type of scan tool or software (how I stumbled on your video) to be able to get into the suspension control because the mag ride sucks and I want to eliminate it completely without using what’s commonly offered out there with plug in resistors that still make the air pump run or something that needs to be plugged into the OBD2 port all the time. Do you know of anything specifically that allows you to get into each module?
For what your trying to do I would say that a scan tool isn't going to work and you would likely need to go with the common kits/methods you were talking about. I believe those systems have a separate control module for the suspension system and the resistors used in the common kits are to keep the warning lists from turning on. I don't think there are any "options" to turn off that system. Atleast not that I have seen.
Doesn't work anymore not atleast for us in Australia with SPS2
Can you reprogram or code new modules on GM cars without a pass through device with any Autel or Launch scanner that you know of? Like a new climate control module and so on?
You can program with an Autel as long as you have the Autel pass thru. The Maxisis Pro is the Autel I believe you need for that. Launch as a similar setup but I'm not very familiar with the Launch tools. On both of them the pass thru is built into the box that plugs into the obd port.
@@apmotorsports5568 I've heard tat even with the maxisis pro, programming is very limited. I paid a lot of money for the MS 906BT, and it REALLY PISSES me off that I can program new modules or parts for most foreign vehicles, but not for F...ing GM cars like what I've got! Yeah I know I can get a $500 pas thru device for GM at DrewTeck....I have one for Ford when I have to reflash the ECU or PCM. But not being able to program just a new part or module to work properly on GM cars without paying for a 2 day subscription is total crap!
Personally I haven't programmed with the Autel, we have the 908s not the pro, but it is a J2534 device so ot should be able to do anything that the drewtech can do. There is also the option of a Mongoose cable which I believe is about $250
Also keep in mind there is a difference between Coding and Programming. Typically you can not Code domestic vehicles like you can with day VW. Coding is used primarily to turn on/off vehicle options. Most domestic vehicle do this as part of the Programming procedures when necessary.
@apmotorsports5568 So I can't code my drls to off and allow cargo lights to turn on when vehicle is moving??
Which VIN do I purchace if I am replacing the ECM and the BCM and the TCM and the PCM all? (For up to model year 2010 pickups) Do I choose the Title VIN and use that throughout? Alo what is this RPO that you mention? Is it an acronym?
You use the VIN number for the vehicle the modules are being installed into. You can find the VIN on the sticker inside the drivers door, in the front left bottom corner of the windshield, or on the title/registration for the vehicle.
@@apmotorsports5568 Excellent. Thank you so much!
Your welcome!
What about the newer version of SPS2? is it still the same ?
The current version of SPS2 works almost exactly the same. The process of launching the program is slightly different but otherwise there is only minor changes.
@@apmotorsports5568 I see thank you, SPS2 use Techline Connect to launch the program do I need to have the subscription for Techline Connect as well?
If your just reprogramming a vehicle then you just just purchase a reprogramming subscription. You buy a subscription for each VIN number you need to program. I believe it's $40 per VIN, each VIN can then be programmed by you for 2 years without an extra subscription purchase. There is a button to click to view available subscriptions, after you purchase, click on the available slot and it will take you to the launch screen for the Techline application. If you want to use diag software or service info there are subscription options for that as well.
@@apmotorsports5568 Thank you for the information. I really appreciate your time.
No problem! Glad I could help!
How to make cardaq-m open in chrome
Recently I've found that the GM application does not seem to like Chrome. It's not the cardaq that's likely the issue you are having. Try switching to a different browser, I use Microsoft edge for gm vehicles and it seems to work well.
do i have to have the battery charger?
Any battery charger with the "Reprogramming Mode" should work. The idea is that the Reprogramming mode provides a cleaner and more consistent voltage level than a standard charger. So far the only vehicles I have seen that need very specific battery chargers are programming BMW vehicles as they require a charger that can put out a very high amperage while in the programming mode.
@@apmotorsports5568 thank you for the response and forgive my ignorance but my first question is does my Chevy Tahoe have to be connected to a battery charger to reprogram modules? and to follow up is this because reprogramming will drain a battery quickly while the car is off thus causing issues?
You should always use a charger when programming modules for a couple reasons. The main reason is that the battery can drain causing the programming to fail and can ruin a module. The other reason is that a charger built for programming will provide a clean steady voltage. If the voltage is fluctuating to much it can cause the programming to fail. Standard battery chargers works by raising the battery voltage very high and then letting the voltage drop before charging it very high again, this is a very simple description and not exactly how it works but for this topic it's all you really need to know. That rise and then fall of voltage can cause issues with module communication during the programming process.
Bro thank you so much I really appreciate it!
Glad I could help!
Hello can I pay you to flash out program my BCM?
Sorry I can't do that remotely. I would recommend taking it to your local dealer or independent shop that can do reprogramming.
@apmotorsports5568 could you possibly reflash one for me if I sent it you a gm PCM. Thanks
Sorry that's not something I do. There are companies you can find with some Google searching that offer that though!
@@apmotorsports5568 ok thanks though I thought maybe since you had the equipment you would charge a fee and I could send it to you but thanks.
For GM vehicles the Service Manual will provide a seperate module programming and cal/setup procedure for each module based on the vehicle build options RPOs. However, the process of reflashing a module one at a time is basically the same. Module setup after programming is specific to the module itself, Keyless entry, TPMS, HVAC, etc.
The GM reflashing procedures state not to use a battery charger and list a service maintainer (EL-49642 (Midtronics) SPS, 2014 Cadillac for example). It is important to understand how the maintainer function works if part of a battery charging system, especially if using jump start posts underhood. The reflashing maximum sustainer p-p noise at 40 to 50 Amps is around 50mV. If the battery charger uses a switching power supply, from a design stand point, it is very difficult to meet the 50mV requirement at currents greater than 20 Amps unless directly connected at the battery.
EDIT: I did a quick check on both the Snap-On (looks like rebranded Schumacher) and NAPA (Confirmed Rebranded Schumacher) wheeled chargers shown in the video. I could not find a noise spec or if the units can use jump start posts. The manual states that they should be connecting directly at the battery for in-vehicle or stand-alone charging. If the vehicle has a battery current sensor monitor function, you would really want to sustain on the vehicle side of the sensor (either a shunt or magnetic), so the battery monitor function can record current flowing into the battery to maintain it's SOC estimation. Midtronics gives a noise spec of 50mV at 50 Amps at the battery, they also do not recommending the use of their products at the jump start posts.
You are correct although I do have a couple things to add. First the programming procedure is the essentially the same for all modules that need to be flashed after replacement, some modules can be setup using a scan tool without using SPS but not many especially with newer vehicles. Second a good battery charger that had a reflash mode will not cause issues with most vehicle manufacturers, BMW is a different story though. Through 10 years of reflashing experience I can say that GM modules will give the least number of problems and I have seen one fail because of a battery charger that has a reflash mode, although I wouldn't trust a cheap one from somewhere like Amazon. I have even seen people flash GMs without a charger at all, although i would never recommend that. BMW is the manufacturer that absolutely needs the correct battery maintainer to be used and they require a very powerful one that very few people have. I have seen BMW reflashes fail because the snapon charger, in relfash mode, can not supply enough power.
Everything you stated is correct, just know that the recommend certain tools often because of a partnership/ownership of the company that makes that tool, i.e why ford had a sticker for many years that said "use BP Gas".
Also, the rpo codes come into play when flashing some modules, BCM especially, you will need to select the correct program to push into the module based on the rpo codes. This process is very simple as long as you read the description of the program you are choosing in SPS.
@@apmotorsports5568 I looked at a lot of chargers to do charging or sustaining at the jump start posts. Mainly for the vehicles that have the Battery in the trunk, of which many like BMW and Cadillac use a current sensor. I use a 2-CH Fluke Scopemeter to monitor voltage at the battery or the posts, and a Fluke current clamp to see how the charger or sustainer is controlling current. I could not find one to do basic quick rapid charging (from the posts) and also supply quiet maintaining voltage for reflash. I ended up making my own 20A 20V linear design for basic repair (single module reflashing) and Rapid charging up to 10 Amps.
When I started taking a close look at the use of jump start posts for charging or sustaining I was amazed at the errors in vehicle voltage as shown on some high end chargers. Meaning they did not compensate for the voltage drop in the 4AWG charging clamp wires or the clamp connection itself. To do this properly at high currents you would need at the very least a 4 wire connection to the vehicle at the clamps. Like the common two 4AWG high current wires, but also two small 14 AWG wires in parallel to monitor the voltage at the clamps. What matters for both a AGM battery rapid charge and a sustainer (as the value given in the procedures, like 13.5V) is the voltage at the vehicle and not the charger.
I would encourage you to take a deeper look at what your charging/sustaining equipment actually does in terms of voltage accuracy and switching noise, either voltage or current.
EDIT: The 20A 20V supply is a linear voltage adjustable with current limit adjust, I use it with a series rectifier to prevent current from going back into the supply when I connect it to the battery or the vehicle.
I'm not at all trying to argue with you, actually I completely agree with your points. I completely understand that the snap-on charger I typically use is not a perfectly clean voltage, snap-on actually came out with that charger probably 15 years ago and have not updated it much since. But for a vast majority of vehicles it works perfectly fine. I've used that charger on just about every manufacturer doing alot of reflashing over the last 10ish years and have never had an issue with it, except with BMW. Some common sense things like turning off lights and accessories are always done to help maintain voltage. And if the battery is accessible then the charger always is connected to the battery. Of course there is a level of voltage drop between the jump start posts and the battery, as there is with any wire/circuit. Personally I've never done the testing of the chargers in the way you have, I've seen it while using scopes to diagnose issues while the charger is connected. I just maintain an understanding of the equipment I'm using so that I am aware of what may be causing issues I've I happen to run into them.
BMW is another thing as once the software starts running you have no control over the vehicle. Failed programming is very common with BMW and almost always because of to weak of a power supply. Very few voltage maintainers are capable of working with BMW.
I do appreciate the info you talked about though. It's great info the know and be aware of, especially for anyone who doesn't have a good understanding of how these systems work!
All you need is this one part..... Then he goes unless all these other parts and machines you need with it and emphasizes you can't use a regular battery charger lol
I may have misspoke, I am not the greatest at talking to a microphone lol. Just to be clear, when I say all you need is this. I am referring to the J2534 Device. The reason I say that is all you need is because I am assuming that the viewers of this video are likely shops/techs that are looking into reprogramming for the first time. Any shop looking into this will already have a computer and most will likely have a battery charger that can do programming as a majority of professional level battery chargers have this ability as long as they were purchased in the last 5-10 years or so.
A j2534, laptop and internet connection. I have programmed without the battery charger. Not recommended but I am willing to chance it😂.
I've done it without the charger as well. Just don't try it with BMW or Volvo. BMW has a very strict requirement for a high amperage battery maintainer to be used. Most of the reflashing capable chargers are not actually good enough for BMW. I've had modules lock trying to flash them. I've also had issues with Volvo, although it may not have been because of the charger I was using.
