Measure absolute angle at front and rear propeller shafts - AR41.10-P-0085-02T

The vehicle must be on its wheels for the measurement. All four angles should be measured in succession without interruption.

An angle that has already been measured can be measured a second time if required. To do this, with the Measurement menu displayed, press the "STEP" button repeatedly until the display indicates Ready to measure the relevant angle.

Measurement - Angle 2: front propeller shaft 

1. Clean contact surfaces for sensor (020a) on front propeller shaft (1).
2. Position sensor (020a) horizontally on front propeller shaft (1) and press on firmly.

   The spiral cable (020b) of the sensor (020a) must point in the direction of travel for each measurement. Otherwise the measurement will be inaccurate.

   If the sensor (020a) on the front propeller shaft (1) is not attached horizontally, the error message "Y-position error, sensor position??" appears. The measured angle cannot be saved.

   Measurement - Angle 3: rear propeller shaft 

5. Clean contact surfaces for sensor (020a) on rear propeller shaft (2).
6. Position sensor (020a) horizontally on rear propeller shaft (2) and press on firmly.

   The spiral cable (020b) of the sensor (020a) must point in the direction of travel for each measurement. Otherwise the measurement will be inaccurate.

   If the sensor (020a) on the rear propeller shaft (2) is not attached horizontally, the error message "Y-position error, sensor position??" appears. The measured angle cannot be saved.
