Hi I have water on my eqc 2021 But very little , key fob doesn’t lock or unlock , car no ignition nothing but I have wiper works all the time for no reason and interior lights works Looking at these connections They look brand new to me ? Any suggestions please v
this didn't fix my problem I changed the 3 on the driver side and passenger side had 2. due to water from sunroof. my fan radiator fan on high mode. and no blinker horn headlights and obd 2 connection not working. any ideas
@DefNotMyBurner did you connect correct connector to correct spot on your can bus ? Did you replace all of the controllers ? I had issue where radio said anti theft and didnt have audio
I have a 2009 c300, no crank, no start at all and no communication with the ECU when plugging in an ODB 2 scanner, I don't get any other lights except for the traction control being inoperative, I have checked the fuses and fuse box/power going to the box, the ECU cable going to the firewall into the car has continuity but no power, I did have an issue about a year ago with water getting into the floor of the back seat after leaking from the sunroof, could it be similar to your issue?
Thats exactly how these can controllers fry, pull front seats, carpet and take picture of each part number on can controller, go to dealer and order, once you have then replace them 1 by 1
@@do0m341 you can check if its ESL , just by hearing the steering lock engage and disengage when entering the key, do you hear steering lock when putting key in ignition?
I need help guys my traction control is on after replacing the modules all the lights went away but when I press on the break traction control light come on Also would love
@@sprinterfix I don’t think they act as terminators. The bus is a parallel bus setup with all the individual modules connecting at that block. All the CAN buss is is a 2 wire network. It allows easy flexibility for automakers.
@@d50erock1975 here is where my confusion lies, apparently these blocks exist for each canbus network from A-E if I am not mistaken, I have heard they provide a set amount of resistance. at first glance they just look like bus bars. I really need to explore this further
@@sprinterfix yes there are 3 resistors on the PCB, surface mounted 60ohm resistors for the high and low channels. They are each connected to a much smaller 20ohm resistor then to a fuse and then to ground. This setup pulls the voltage down from 12vdc to something in the range of 2.2vdc.
My 2012 mercades had anti theft activated on the sterio screen and when I check under the carpet there was water and re wired the ones that look like got affected by water and still doing the same car doesn’t turn over and when I try put the scanner it doesn’t read anything like it turns on the scanner but scanner just searching and wont read anything
Theres more under passenger side carpet ,take passenger seat out, one of my w204 c classes had radio issue where it said anti theft on screen. Ones under passenger side carpet was the issue.
@@pandydiy the passenger can busses correct? Or are you talking about other sensors ? Cause those look fine they don’t look water damaged do you know why my ob2 won’t give codes like has no communication
@@laloarmas6491 passenger can buses yes, i suggest you remove passenger seat and pull up carpet, if you dont find obvious water then im sure they've gone bad from humidity
These are some kind of power distribution boxes, they have a electric board inside them and these control they electrical system power distribution, these cost 10-15 dollars each at dealership, part numbers are on them, I also had to fix some wiring due to heavy corrosion.
@@pandydiy oh wow, I don't think I can handle this repair myself, after watching ur video yesterday I checked the floor mat and it felt wet so I took it of a little n found water under it, I plugged in my scanner and found 3 codes, 2 of the same you had.. after water drained car cam back on... Before that car will not go into gear. All light flashing. What's you advice for me to do
@@fransuaanthony6847 i had the same problem, car started up once in a while, didnt go to gear , lights flashing, Mercedes should have similar electrical set up, my connectors mostly was so bad that wires was poppin out from the plugs so I had to cut the wires and connect them straight to each other and solder them to assure best connection. Someone who can solder wires can do it. It was first time for me as well
Im not sure if it has anything shifting related on these can buses, transmission control unit on these transmission are transmission internal , mounted on the valve body
@@pandydiy perfect sounds good, im dealing with a similar issue where the car was partially flooded, lights are working fine and such, no comm errors, just some wierd shifting, had the tranny replaced and re-married and still kinda giving me the same issue of when it shifts the rpms rev along with the shift, kinda weird I'd say
@@pandydiy Initial problem was the rev on shifting, car was partially flooded, so the tranny had water in it, so I was thinking due to the water, the rough shifting is caused from the bad tranny. Had it swapped and re-married, car still has rev on shifts. It's a 08 merc. Benz. C300 4matic. 7 speed tranny i believe
@@abdultokhie8648 any codes from transmission control unit ? And yes its 7 speed 722.9 trans These can bus controllers are cheap from dealer, pull your front seats and carpet to access ones on driver and passenger side , just to be on safe side Id replace them. Take pictures of your controller part numbers and order then from dealer, then swap them by taking one connector from old controller and right away putting it into new, at least you dont mess up what connector was where like this
My question as mine also hqs transmission problems. The transmission control box is located on the footwell under the cabin. Cleaned my connecters bit better now

You got lucky with that one. Good work
Hi
I have water on my eqc 2021
But very little , key fob doesn’t lock or unlock , car no ignition nothing but I have wiper works all the time for no reason and interior lights works
Looking at these connections
They look brand new to me ?
Any suggestions please v
damn that sucks. water damage is the worst
Thanks so much I’m doing this now! But did you leave the drain clogs open? How do I prevent the water from doing that again?
@@user-yg1bu9lv3g clean your sunroof drains
@@pandydiyit just happened again man smh how do I clean my sunroof drains? Any videos you recommend to watch?
And I also found that the windshield wiper seals get weak so the main cam in engine can also have water in it from the leak
this didn't fix my problem I changed the 3 on the driver side and passenger side had 2. due to water from sunroof. my fan radiator fan on high mode. and no blinker horn headlights and obd 2 connection not working. any ideas
I have the same issue GLK 350
Did you ever resolve it? I’m having the same issue right now stranded
I also did the same thing still the same
Did your guys sort the problem out
Problem is probably from SAM
The result is useful
How did you order ? Part number. Thanks
All parts have diff numbers if you can see them take a pic of the face you’ll see it
Different year the part is different
Hi, Pandydiy nice video I have 2008 c300 will this also have anything to do with windshield wipers and turn signals and horn not working too ?
Definitely give it a try
@@pandydiy Thanks
I have the same issue 2013 c300. How do I splice the wire from the white connector. It seem they have a odd number of wires male vs female. Thank you
hi, what will be the resistance specifications for high/low bus system?
I replaced mine and I now lost audio in my car, does the driver side or passenger side CAN BUS control the audio? I have a 2013 C250
@DefNotMyBurner did you connect correct connector to correct spot on your can bus ? Did you replace all of the controllers ? I had issue where radio said anti theft and didnt have audio
To know how the connection need to be connected probably one’s not connected properly
Same problem where does the lose wires go.

@@pandydiy Thank you I will get in there tomorrow morning.
@@do0m341 report back once you have done that
@@pandydiy Hey I checked under the carpet and there isn't any water nor any obvious damage to the wiring, maybe a bad ESL?
@@do0m341 you can check if its ESL , just by hearing the steering lock engage and disengage when entering the key, do you hear steering lock when putting key in ignition?
Do the cable locations on the canbus matter? I had mine changed but forgot to label them 😅 wasn’t able to fix my issue
All connectors should be labeled or transferred over from old to new one by one to not mix them up
W204 c300 2011. Wheel sensor issue .. I have changed hub and wheel sensor yet ..Abs and stability sign is still on my dash.. I need help
You should start by scanning codes
Please how do i read w204 ISM CAN wire with a multimeter
If not CAN bus connectors, front SAM issue ☝️
@PANDDIY what did you do about the clogged sunroif drain?
I used pressure air to blow it open and water hose to flush it out,
what is the part number for those three connectors at 3:38 ? Thanks! :)
@@MsBot100 can controller part numbers vary based on VIN
I need help guys my traction control is on after replacing the modules all the lights went away but when I press on the break traction control light come on Also would love
Scan for codes first and then diagnose from there
what exactly do those distributor blocks do? I see lots of ground wires leading through mine
these are for the CAN databus system. These are distribution blocks. Don't be fooled by the green wires, they are not grounds.
@@d50erock1975 so they terminate canbus signals in order to eliminatte canbus reflections?

If you this can connectors rong place it will make problem because I seen you have marked oncan cables ?
Im sure there is a place for each connector, I didnt want to take my chances of finding it out
Thanks for your reply
Please tell me haw to test can bus with multimeter with ignition on position ? Thanks in advance
