This code can be set when the PCM detects that the TCC is not engaging or disengaging properly. This can be caused by a variety of factors, including:
A malfunctioning TCC solenoid
A problem with the wiring to the TCC solenoid
A malfunctioning PCM
Low transmission fluid level
Slipping transmission
To diagnose the problem, the technician will need to perform a series of tests, including:
Checking the transmission fluid level
Inspecting the wiring to the TCC solenoid
Testing the TCC solenoid
Scanning the computer for other trouble codes
Once the technician has identified the problem, they will need to repair or replace the faulty components.
