what ive done ive checked all fuses and cleaned them, checked relays and connectors or pcm and ebtcm. ive cleaned and re secured all the grounds i can find. car starts and drives fine. Wondering if anyone has a list or good diagram with all the grounds for the engine/pcm and info on how to actually diagnose the pcm and ebtcm? Ive searched and found some random stuff. engine light i on and traction control light is on.

if anyone needs more information i will help as much as i can.

Thanks in advance!

Also what is suppose to be hooked up under drivers seat with serial data cable and Ethernet looking cable and also a round screw in type cable?

 

i got the tcs data to show in ipc now a couple wires came loose from someones previous repairs right at the black box with the silicone where the harness passes through the firewall. in addition ive cleaned all the grounds and went back through the bat connections and body and engine grounds. ive checked the pcm wires that are ground and power and all are good. where could the pcm data wire be severed i am at a loss with this no pcm data crap lol. since getting ebtcm to show up on ipc i get the tc0073 code so tc light is still shining strong. any ideas would be great..

 

When I bought the car, everything was fine, but literally a year later, problems with electronics began to arise, the audio system in my car began to malfunction and navigation also began to malfunction. I didn't understand what was going on, but I didn't repair my car in the first minute, because at that time there was no money. Then when I had the money, I took the car for diagnostics and the guys from http://salvagedata.com told me that the problem is in the central computer, namely in the hard disk of the central computer and its failures. When my hard drive was repaired, the problems with the electronics immediately got better and the machine began to work properly. I am very glad that everything is alright and my car is in good order now.

 

The thread is old and I don't thin you will find help here. I suggest creating a new thread
