- This Land Rover was a very difficult vehicle to diagnose and was sold “As Is” at auction because it was unable to be repaired. The ATS eSCOPE Elite & eSCAN Elite were used in the diagnosis.

How is this car not setting any trouble codes?? Crazy Land Rover!!
Did u learn anything, see how he makes a complete video including the repair?
I think Bernie should do some consulting with the automakers to help them flush out gaps in the diagnostic programing and engine control systems for ICE vehicles.
You’re the worst TROLL of them all.
I am so glad to see you doing more videos Bernie. Miss you in ASTE. Blessings hope you feel better
Bernie said: This car is very sick. = He loves so much and has so much passion of what he is doing,that he gives them soul and human dimension/personality to cars.
Well done MASTER. keep teaching us.
Some times they can be testing 🤔☹️ . Making money on these kinda jobs is impossible, but I get grumpy & won’t give up until I find an answer which definitely doesn’t pay.
Well done for getting it running correctly 👍. Keep them coming Bernie 🙏
If you're not making money on diagnosis like this, you're not charging correctly.
You know it's going to be great video when it's over 1hr long . 👍
Bernie is amazing at sticktoitiveness ! Even when you got the engine running the way it should, you still see something that isn't right!
The ATS tool does what many others won't or can't do.
Great diagnosis Bernie, corrosion was the problem, as were the wrong solenoids.
Scope, knowledge and experience all together. Thank you for sharing.
you definitely have more patience than 99% of line mechanics
You know its a been a tough diag job when there's a haircut involved
A tough one I could feel the pressure in your voice but as ever you came out on top your the man thanks for the video
Appreciate your effort, patience and time making these videos
What a story !!!
Thank you for the great video Mr.Thompson!
Still can’t believe it didn’t set codes when it ran like that good video
LR2 = Lost Revenue Too. I live in the Salt Belt . I have a scope but I am primarily a scanner user, and if no codes and running wacked out, I test power and grounds and always inspect the pcm connectors and try to wiggle the ECM connectors , remove and reseat the connectors a few times times first before busting out a scope. if I feel a PCM isn't working logically. Many ECM connectors are hooded, taped, ziptied, and so miniaturized, that the typical back probe needles are too thick to safely back probe, and wires too small of a gauge to safely pierce
I'm wondering if the PCM has an adaption to learn the VVT mechanical differences. As components don't respond as they used to the deviation in timing and phaser performance is learned and adapted to. These usually should be reset somehow using a scan tool function when new components are installed if that option is available. Maybe the PCM from the donor vehicle had a lot of deviation which wasn't cleared out of the adapts, so it was running using that adaption. That would explain why it didn't flag any codes. Seen a 2015 Subaru WRX have a new timing set installed and the PCM kept flagging a P0019. The solution was to replace the PCM because the CMP/CKP variation was learn on the old set and there is no way to reset the variation from memory.
That is really interesting, thank you for sharing that experience.
thank you! please never stop doing videos 🙂
I need to get my hands on the E-Scope
Really like your videos and the way you approach such problems step by step. Any particular reason why you did not consider reflashing the ECU? Would not be the first time that somebody tried to cover a real problem by changing some bits in the software.
Great job hard work and quiet a lot of brain power needed. I thought it was going to be ecu not coded properly. Well I was wrong but like watching your thought process. Well done again.
Bernie fixed the car, but perhaps the final piece of the jigsaw was a relearn cam and crank, needed
Excelent diagnosis proces. Thank you for sharing this.
These land rover or range rovers whatever they are called are a nightmare to work on. I don't even think there is one dealer near me that will work on one. We took one in on trade years ago and the four ways would start flashing randomly when driving down the road. We sent it to a dealer and they said one of the modules in the car has to be positioned correctly in it's hold down bracket or that could happen. I had never heard such a thing but that's what the problem was. We had to send it to a dealer about 200 miles away to get it fixed, how bizarre.
Wow. Interesting. I wonder if VVT activated during test drive. The current shop installed that ECM, but Rover arrived with a problem; did both ECM's have corroded terminals, or the bad Exhaust VVT valve was original problem, and shop compounded it by installing filthy ECM? I wonder how many hours BT charged for that job. And +100° in variable lobe separation potential is amazing; i recall building hot rods in the 1980's, and the difference between a smooth idle and lopey one might be only 12° from one spec sheet to another. GREAT VIDEO 👍.
thanks for sharing , love those mystery with a good ending
Thank you for the priceless information Bernie. You're a good man.
Wow. Thanks for your teaching Mr. Thompson !
Outstanding work sir.
it's amazing how many problems can a bad software cause
U r really top gun mechanic,
I bet Bernie spent several hours on this vehicle. Heck, looks like he got a hair cut >>>!!!. He even scope the powers and ground but no load test. Great job Bernie and for the terminal cleaner tip ( I just bought a can from amazon)
Hope the new customer buys an extended warranty.
I’m surprised someone bought a none working Land Rover from auction. The only way to successfully flip them is to have a fleet of cars to scrap parts from.
There’s a garage around me that buys nothing but none running BMW at auction, but he has 50 dead ones laying around at any given time. But the guy knows BMW, last I heard he charges dealerships $250 an hour to do mobile diag.
Amazing Diagnosis details!!
a .17 rifle brush works good on some ecms. i was expecting in cylinder pressure test to be performed to verify timing. with a turbo it throws a wrench in if it wants boost to allow the cams to be commanded more. dyno or road test. would have been intersting to see if the cams moved more on the road test.
Bad part is the vast majority of mechanics don’t even think this is possible 😂😂😂😂
All you have to hear is it's a auction car and you know it's a basket case I enjoyed watching the battle I wish money was no object would liked to have seen bernie go all the way on this one
Brilliant 🇺🇲👍
Great stuff stabilant22.. loveing it
The GOAT
You're the "Man" Bernie!
"What conditions must be met before a code can set"
I'm no expert, by far, but wouldn't it be possible for codes to not set, because system monitors are not complete?
I would imagine that for SOME codes (non hard fault) to be dependent on monitors having successfully completed... ?
Great question. There are two types of monitor systems; continuous and non-continuous monitors. Continuous monitors include Comprehensive component checks, Misfire and Fuel system and are running as soon as you turn the ignition to ON position and will run all the time until you turn the ignition OFF . Variable valve timing checks are of continuous monitor, and are ongoing all the time as it falls under Fuel system monitor. Fuel System monitor detects any changes in fuel mixture that may cause emissions to increase.
What I don't get is why does the computer see only a small movement of the camshaft. Doesn't the pcm use the camshaft position sensor to see the amount of movement. So if the cam moves 50 degrees on the scope based on cam sensor movement shouldn't the pcm see the same 50 degrees of movement?
i like the ATS diagnostics tool
Awesome video Bernie. I just don't understand why the AMP clamps on the E C M power and the ground test you did didn't show anything with the dirty connections.
Unfortunately didn't get much of the cam and VTC explanation but In BMW I sure seen alternators and loose ignition coil grounds set cam/crank faults or vanos faults now I add power amd grounds. Too bad the scope didn't see that.
Nice Job
You are the best!!!
Wow. That was a crazy one! Peace
Thanks Bernie!
Bernie is the chuck Norris of the diag world...they say Bernie doesnt need a known good hes the known good. LOL
Would have been fun to see what the other problem was.
Why didn't the amp draw test and voltage test on the pcm show any voltage drop from those corroded connections. Wonder if the original pcm was fine and the wrong actuators were the problem. I have seen some manufacturers won't move the cams unless it's in gear or a speed signal input received.
The man, not the myth, the legend
Let’s go😁
I had this same problem on my Chrysler product computer connections. I cleaned the contacts and what was happening was the computer symbol for cruise control had to be pressed several times to get cruise control on. Since cleaning the connectors into the computer now it clicks on first time every time.
I didn’t see you disconnect the battery…don’t you think you should have before you used a metal brush on the computer plugin connection ?? If so probably should advise the rest of us?? I think the brush bristles could cause a short and maybe another problem??
At 1st with the symptoms I was leaning more towards the coronavirus lol. Maybe to early for jokes like that
Awesome.
Your so much better than the want to be diag techs!
Wow, this is a tough one.
I wonder...since the pcm power voltage is reduced due to corrosion wouldn't the amplitude of the scope readings change as well? I know that sometimes if you have bad power/ground feeds to a pcm it will change some pids.
How do you get 50 degree out of a phaser? Ford do about 20 or so.
❤ very very good
Crazy car for sure, no codes??
On Bernies Land Cruiser my suspect is corrosion internally on the board. The new owner needs the computer opened and cleaned internally to rid it of water intrusion corrosion. A computer geek has to do this or it will never work again.
Is that rattling noise coming from the engine we hear while he’s showing scope hooked up?.
Try the Original ECU if they have it!
i'm confused about where Bernie gets that spec for an edge of the CMP pulse coming 75deg before the CKP sync pulse. Is that a LandRover spec? Never seen it mentioned ... Also, did Bernie say that the Intake and Exhaust Cam waveforms for each bank always exactly overlay their mirror waveform on the other bank?? I've never paid close attention, but I'm not sure that's always the case??? Anyone know for sure?
This is a land rover specific thing as he mentioned. He pulled up a recording from another like vehicle to compare as well. Most cam/cranks I’ve scoped don’t overlap like this one.
The oscilloscope your using, I notice your able to also read codes. Is it a scanner/oscilliscope combo in 1? Great videos, thanks for sharing.
Relearn? Readaptation?
maybe the 20% duty cycle car had some pin corrosion issues too and 8% is actually normal? :d
or what is duty cycle even lol
can you give a better description of the electrical contact cleaner... I cant make out the brand
Otherwise , contact ATS .
Tech Spray 1621-10S EcoLine Flux Remover, General Purpose Defluxer
There is a TSB on the vehicle
Is it worth investing time in to this..? Interms of payment..
Of course! When you can make these types of diagnosis’s from what I’ve gathered it eventually gets you your hourly rate and ur spending 30-90 minutes. You bill them for the full time. Look at the parts that won’t get “Cannoned “ onto the vehicle needlessly. Charge your worth!!
Hi Barney
How comes the amp draw test didn't show that the pins were coroded?
YES,NO or MAYBE😒 applies to more than just cars🙈
As I'm seeing back of that computer, probably are second hand, that means somebody trying to fix that car before.
Land Rover computers are more fragile than a glass vase in the hands of an angry Karen.
Codes have been removed from flash, this is hilarious how some people try fixes just by removing fault codes.
1st!
