Description Fault while measuring the sensor voltage Effects on the driving operation Hard retarder activation No braking in first gear (no braking with RBK disks) Possible causes Error while reading the sensor voltages U(nA) or U(nB). The fault is probably located inside the control unit. Place of action Transmission control unit Instruction Replace transmission control unit. Setting conditions of the event No description available. Test 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 the function.
