Steering Angle Sensor Damage During Removal and Installation of Jacket Tube
For Model 163 vehicles, please ensure WIS document AR46.10-P-0400GH is followed and adhered to when removing and installing the jacket tube. Do
not separate the coupling (Figure 1, 1) below the Steering Angle Sensor (N49) or damage to the sensor rotor may occur. A damaged sensor due to
improper jacket tube removal/installation may trigger the following reoccurring fault codes: C1172 (Steering Angle Sensor Internal Fault) or C1174 and
C1178 (Steering Angle Sensor Not Initialized). If the Steering Angle Sensor is found defective, do not transfer the Steering Angle Sensor from the new
jacket tube to the previously installed jacket tube.
