Hei Dawn, any result? Im struggling on my XC90 2004 2.5T, there is strange codes from CEM, but related to TMC.

@@nurka489 unfortunately no. The immobilizer locked it up and I haven't been able to reset it. I ordered Stabilant 22 from Amazon. It's supposed to create stronger electrical connections. I will use it on the antenna ring connection as well as the ECM and TCM. If that doesn't work, my next step will probably be xemodex. I really hate spending that kind of money though. Especially when I know it's something with the car's computer, not a bad transmission or anything.

@@dawnrobbins5877 Thank you very much for your prompt reply! I lost the antenna light ring recently. Im not going through xemodex. It doesn’t worth the money and time. Did recently cleaned TMC and EMC with contact cleaner spray, its performing a little bit better. Can you send me a link of amanzon to check it pls?

@@dawnrobbins5877 a quick update. After a long consult with mechanics of the company where i do work, i decide to buy a new battery. The new one is 77AH, with 760 cold start, the old one was 70AH with 660 cold start. It seems, that TCM, shift lock errors on CEM did disappear. Its been 2 days now, i didnt drive too much, but to go work and back home, i have to go up and down to a small hill. Didnt felt any issue at least with gearbox. If i get something new, let you know. But, how old is your battery?

@@nurka489 I too bought a brand new battery, 760 CCA. Still can't start the car because of the immobilizer. I'm hoping to get back to the project soon, but for now I have it on the back burner. My goal is to have it in good shape by the end of the year. So, do you think your problem was solved by the new battery? I sure hope so!

my car has very low mileage (37.000). I believe his previous owner was never able to figure it out what was going wrong with the car.

Hello, my car is in limp mode and has trouble starting. It cranks, but it doesn't. I've previously changed my ecu and thoroughly examined the wire harness, but I'm just wondering whether my car might also be affected by the same reason as it’s damaged and the knob on my controll assey heater has come out and theirs a motherboard at the back of it. was your control assy heater broken by any chance? did it also crank and have no start?

@@Unicornkitty-ni7kh no, my car was able to start, the only problem that had was the limp mode and some lights on the car dashboard. In the mechanic, they changed the harness but didn't resolve the problem. It was solved once they changed the CONTROL ASSY-HEATHER.

@@elilucha by any chance, do you still remember what lights were on your dashboard? as my car has the glow plugs, down hill and slip light control on

@@elilucha could you still change gears perfectly or was it in lock?

was something else causing the u1000 code ? i currently have it along with p0882 and p0726 both no tcm signal codes but i can’t find anything to fix it

Any luck ?

Random

what he did is an alternative wiring route, more direct sort of say.

Thank you for your comment

He probably haven't finished buttoning it up yet. He left it so that we could see the bare wires.

Did you solve the problem?

How did you solve the problem

@@kimonshisagat1635I’d try ecm the car is grounding out at least in my case with a Audi s5

@@kimonshisagat1635I think it’s motor mounts but can be other issue test all the ground with the car computer see what there reading

I grounded each one together to the body of the car

Some variables to consider: Is that your original injection pump? Open up that injection pump cover, remove the throttle linkage, and check those few wires for their integrity. You know that on these trucks they are NOTORIOUS for bad grounds. There is that black wire that goes from the fuel pump relay trigger to ground. But on it way to ground it hits Joint connector #1 in the PDC and then heads for G102 ground location. (Left fender) P1689 code is from the Fuel pump realy being dead just clear the code and you should be good... But fix the wiring right though. Recheck all battery cables. If you are still running factory battery cables, check they for corrosion. Hope this helps. If you haven’t already subscribe to my channel; got loads of videos dealing with these second gens. Happy New Year

conquryourfear & do it urself thanks a lot

I want to try this but you got me lost on step 2 can you explain better or draw a schematic on this ?

Ecm trouble shooting and reprogaming

May the Gods of Luck be on ur side tomorrow!!!

GET A WIRING DIAGRAM AND CHECK THE GROUNDS FOR THE ECM. iF YOU LIVE IN AN AREA WHERE THERE IS SNOW AND THEY SALT THE ROADS YOU COULD ALSO HAVE HIGH RESISTANCE CORROSION IN THE NEGATIVE BATT CABLE.... I HAVE SEEN THESE CODES DISAPPEAR JUST BY REPLACING THE NEGATIVE BATT CABLE BUT IT IS NOT 100% OF THE TIME

P1590

UO100

Mines showing a p1605 and when I look at the problem this is it

How do you mis-connect the TCM? It’s a plug in. But your thought about the neutral switch is worth looking into

It’s easy to misalign the pins. And sometimes it’s not pushed all the way in.

I have subaru crosstrek too workforces you !!!

You are one of the lucky ones!!!

@@conquryourfear your probably right...I had the motor replaced under warranty just 8 months before the 10 year powertrain warranty ran it's course...have a 2011 RVR with 7000km on the engine now

Other than taking your cluster out to remove the bulb ? No

@@conquryourfear I did not get your point. Can you clarify please ?

@@abdelchemami6964 well. I just cannot think of any other way to prevent that check engine light from coming on, except for removing the cluster and taking out the bulb that lights up the check engine icon.

@@conquryourfear okay 👌 thanks

Thanks for you valuable insight

@@conquryourfear 💯🤣

Is that will be if the oil fluid not the same

I'm saying this help me with my car. It doesn't hurt to try.

I will double check them for good measure

@@conquryourfear ..cool I'm having same problem but I think my negative terminal is just loose or faulty

Did you ever figure out the solution? I’m having similar issues but I want to actually fix this issue without running hot wires around plastic.

lol i am here looking for answers because of my g6.. the fluid is good and a new tcm but traction control is coming on.. possibly the wires

@@caras5590 hello ive had 3 of these cars. what do mean traction control comming on? its supposed to come on you turn it off with button down by pasenger air bag light by shifter. if your car was recently worked on they probably did something wrong, wish i knew you got a tcm you didnt need one! they rip people off! the connector that plugs tcm in was problem! if you tell me what its doing exactely ill research for you. im a disabled marine vet nothing else to do! you could have bad trac cont motor. tract contr keeps the car from burning rubber baby! pealing out! i hate it!! comes on when turn car on automatically. you turn it off by pushing button under stereo all way at bottom by gear shift and airbag bag light. miss cara s

Hello I have a 2012 Impala that I can't get emissioned and tagged right now due to traction control syabilityrak light and check engine light. We changed the TCM but about 3 months later all lights come on again. I don't know what to do now cause can not pass emissions

Hard to tell. I know the u1000 is the computer can’t figure out something. Needs to be driven more to throw a code. As for the ratio code. That alone sounds like a transmission solenoid is shorting or grounding out.

@@conquryourfear thanks that’s our thought but there’s so many things it could be so we’ve been trying to do the elimination process. Won’t take off in the right gear it takes off in second, slow acceleration but drives fine and then it pops back into 1st gear once it hits about 30 mph and drives fine. No reverse at all it tries to move but acts like a parking brake is on

@@arielchantel5644 Bad transmission solenoid’s will do all of that

@@conquryourfear I appreciate it I’ll for sure make sure I bring that up to the mechanic 👍🏻 I’m not sure how to check one unfortunately

@@arielchantel5644 it depends. Some require you just remove the transmission pan and you have access to all of us Solenoids. Others you have to take the transmission out. I do not know what the deal is with yours though
