Instruction

Delete the fault from the fault memory

Restart the transmission control unit.

If the fault reoccurs, check the connection between the transmission control unit and the TIM.

If the fault occurs regularly, contact the Voith customer service.

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.
