Description Short-circuit or low-resistance connection to supply voltage at negative sensor terminal. Effects on the driving operation No retarder operation. No switching into reverse gear. No ANS-function. Only change gears to protect the engine against under or over-speed. For substitute functions, possibly hard shifts and hard retarder activation. If the engine transmission output speed sensor is simultaneously defective, only limp-home mode available. Main pressure to maximum. Reduction of the engine torque to protect the transmission. Possible causes Short-circuit in plug connection, cabling or sensor. Place of action Transmission output speed sensor (negative terminal of the sensor or the sensor circuit) Instruction Check plug connections, cabling and sensor. Setting conditions of the event No description available. Testing 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 function. After the fault has been eliminated, the following steps have to be carried out: Conduct a test drive with function check. Read the fault memory Check transmission for leaks. Perform a final visual inspection. These steps are necessary to ensure the entire vehicle functions correctly. See also:
