Engine torque: Diagnostics

If the information on the engine torque is incorrect, diagnostic trouble code C1928 will be generated, the TCS function will be disengaged and the TCS OFF lamp will come on.

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

If TC/ABS is programmed for the wrong engine variant or gearbox, diagnostic trouble code C0551 will be generated.
