Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition




The brake control module (BCM) puts a signal for the vehicle speed on the CAN network. The transmission control module (TCM) uses the signal to diagnose the gearbox input and output speed sensors.
If the transmission control module (TCM) registers that the signal from the brake control module (BCM) is missing or indicated as incorrect, the diagnostic trouble code (DTC) is generated.
