Place of action No description available. Instruction Check the CAN message / CAN signal and correct if necessary. 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.
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:
