Getting "Controller Unlocker: Timed out."
2010 CTSV it will write to the E67 ECU and then pauses for 15 seconds.
Tries to write the T43 TCM calibration and after about 2 seconds throws the "Controller Unlocker: Timed Out".
I checked the resistance on the ODBII pins 6 and 14. I am getting 65-66 ohms of resistance which from my research is too high. My research found that 58-62 ohm is desired range.
How can it read and write the ECM every time but fail on the TCM every time if the Hi speed LAN is having problems communicating? (40+ attempts of several days of troubleshooting.)
I just updated HPTuners to 4.4.4.0 and no change in behavior. The upgrade even updated the firmware on the interface.
Car starts and will move but it is stuck in limp mode (3 gear) and the dash is lit up like a Christmas outdoor display.
"Stabilitrac Off"
"Parking assist Off"
"Service Stabilitrac"
"Service Tire Monitor System"
"Service Traction Control"
All grounds seem to be good and I have 12.5v (14.4v when running) at the battery and fuse box.
I have tried test hanging 2 different known good 6L90 TCMs from another 2010 CTSV - same results.
VCM scanners reports code U0101 - Lost communication to TCM.
Any help or guidance is much appreciated.
Thanks in advance!
