Description The operating voltage of the gear range selector is outside the allowed tolerance compared to the operating voltage of the transmission control unit. The allowed deviation is +/-5V Effects on the driving operation The flexible inputs and the flexible output at the gear range selector are non-functional. Possible causes Ground potential difference between transmission control unit and gear range selector Smaller operating voltage of the gear range selector than the transmission control unit. The analog-to-digital converter in the gear range selector is defective. Connection of the CAN gear selector switch Connector pin assignment of CAN gear selector switch

Place of action 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 voltage difference between gear range selector and transmission control unit. The operating voltage difference measured against the respective ground potential of the control unit must not exceed 5V. Check cabling. Setting conditions of the event No description available. Test 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 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:
