C0241

Read the instructions below then start the fault diagnostic procedure.

Symptom: TCS OFF lamp on, no TCS function.

C0241


Engine Torque Limitation. No or Faulty Signal/Wrong Variant Programmed/Trionic Limphome.


Fault symptoms

TCS OFF lamp on, no TCS function.

Conditions

The Trionic can detect 3 different faults which affect TC/ABS modulation. The Trionic then sends a 96% pulse ratio as an engine torque signal and the TC/ABS function then sets diagnostic trouble code C0241.

The 3 faults are:


• Break/short circuit in the lead for torque limitation.

• TC/ABS programmed for wrong engine variant.

• Fault in the Trionic's throttle control (Limphome). When this fault occurs the CHECK ENGINE lamp also comes on and the cause of the fault is in the Trionic.


Diagnostic help

If the CHECK ENGINE lamp comes on in connection with diagnostic trouble code C0241, the fault is probably in the Trionic's throttle control. Obtain a readout of the diagnostic trouble code in the Trionic and rectify the fault.

If the CHECK ENGINE lamp does not come on, first check to see whether the TC/ABS function is programmed for the right engine variant. If the programming is correct, engine torque limitation can be activated by a command on the diagnostic tool.


- Select “Activate”

- Select “Engine torque limitation”


The TC/ABS control module now requests the Trionic for maximum torque limitation.
