Description Brake pedal permanently applied Effects on the driving operation Functions which are triggered by a certain brake pedal position are not available, e.g.: * No ANS. * No gear release (no drive mode). * No retarder activation if it is requested via the brake pedal position. Possible causes The brake pedal position received via CAN has never shown a released brake pedal 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 leads to a too great brake pedal position. * The sending control unit delivers a too great brake pedal position. Place of action No description available. Instruction Setting conditions of the event No description available. Test conditions of the event No description available. Troubleshooting
|  | NOTE The following service work may only be performed by persons who are authorised by the vehicle manufacturer: Loading software and/or datasets into the transmission control unit. Service work at vehicle components which are not included in the VOITH delivery.
Check whether the brake switch provides a pedal position '0'. Check the CAN message and contact the manufacturer of the sending unit if necessary (with SAE J1939 see EBC1 (Electronic Brake Controller #1), 'brake pedal position' ). 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 the function. After the fault has been eliminated, the following steps have to be carried out: Conduct a test drive with function check. Read out the fault memory. Check the transmission for leaks. Perform a final visual inspection. These steps are necessary to ensure the entire vehicle functions. See also:
