Rotation speed measurement at Transmission output
â–¶ How to fix
Check sensor. Change sensor. Check voltage. Check plugs, plug contacts, plug connections and cabling. Change transmission control unit and send it to Voith customer service for diagnosis.
What you'll see
No driver-visible symptom recorded.
System reaction
ANS operation limited. Limited driving operation. Transmission control unit switches into the operational status neutral, forced neutral or waiting for neutral. No or limited retarder function. No or limited reverse gear acceptance.
Diagnostic depth
Detection
Sensor voltage too high. If the sensor voltage exceeds 13V, the speed sensor signal cannot be processed anymore.
Possible cause
Internal control unit defect of the E300.1 hardware. Low-resistive connection (short circuit). Sensor defective.
