Description Braking torque continuously greater than '0'. Effects on the driving operation No retarder operation. Possible causes The brake torque received via CAN has never been inactive in the current operating cycle although it can be assumed that the vehicle was not permanently braked. Possible causes are: Defect at the brake switch that permanently causes a valid brake request. The sending control unit does not deliver a brake torque '0' via CAN. Place of action No description available. Instruction Check whether the brake switch provides a brake signal '0'. Check the CAN-message and contact the manufacturer of the transmitting device if necessary. Setting conditions of the event No description available. Testing conditions of the event No description available. Final function check If the defective component cannot be clearly identified, you should try to reproduce the fault: Reinstall the component in the vehicle. Test function. After the fault has been eliminated, the following steps have to be carried out: Conduct a test drive with function check. Read the fault memory Check transmission for leaks. Perform a final visual inspection. These steps are necessary to ensure the entire vehicle functions correctly.
