Voith-Retarder
Reading out the fault memory
- Retarder step switch in zero position. Switch off ignition and connect up request button
- Switch on ignition
- Press button for > 2 seconds
When the first fault code has been emitted, emission of further codes will be automatically
interrupted. For the next fault the button must be pressed again for at least 2 seconds.
Duration of a ten...............................................................................................approx. 2 s
Duration of a unit..............................................................................................approx. 1 s
