Engine torque: Diagnostics

In the event of erroneous engine torque information, the diagnostic trouble code C1928 is set, the TCS function is disabled and the TCS OFF lamp lights up.

In the event of a fault in the Trionic system's throttle control (limp-home), the CHECK ENGINE lamp will come on and the fault can be found in the ECM.

If TC/ABS is programmed for wrong engine variant or transmission, diagnostic trouble code C0551 is set.
