I was driving the car with check engine light for awhile it was for camshaft position actuator circuit. The car drove just fine but one day it started jerking slightly and then would accelerate really slowly and not really go over 20-30MPH. I got home and checked codes i got the check engine code and i also had NO COMM. with TCM and faults on the ECM and BCM(i assume they are because or the TCM fault) so I replaced the bank B solenoid which is what the code said. Still same issue the check engine code went away but others remained. So i swapped the TCM and checked TCM fuse everything is good but problem still persists what do i do. Any ideas? Thanks

 

post all the codes that set and post which modules set the codes. then clear the codes and post which codes reset and are active (not stored) and what modules the codes are set in

 

Sorry didn't get a chance to rerun the codes till now. I cleared codes previously so the ones that are left are
For ECM: U0101-00 Lost Communication with TCM
For BCM: U2106-00 Lost Commuication with Transmission Control System
For TCM No Comm.
For HVAC Control Module No Comm.
For Electronic Brake Control Module: U2106-00 Lost Communication With Transmission Control System/ U2105-00 Lost Communication With (ECM)
For Power Steering Control Module: U2100-71 CAN Bus Communication/ U2109-00 Lost Communication With Powertrain Multiple Control System/ C0000-71 Vehicle Speed Information Serial Data Received /
C0460-00 Steering Position Sensor

 

the vehicle uses a daisy chain bus CAN C computer architecture. Since all the other modules on the bus are communicating...the bus lines are fine....check power and grd to the tcm.

 

Thanks for the reply any idea as to schematics for power and ground on TCM?

 

you can buy a service information membership to michell ondemand for 1 vehicle. it will have all the info you require. where to get it free i have no idea.
