CLAAS 762Ch: Steering Angle Sensor Voltage Issue (TR2 A57-2, Code 762Ch)

The steering angle sensor (B117) is reporting a voltage outside the acceptable range of 0.5V to 4.5V. The transmission module TR2 (A57-2) interprets this as a steering angle of 0°, which triggers the diagnostic lamp to blink.

1. 1

   The voltage output of the steering angle sensor (B117)

2. 2

   The connection and wiring between the steering angle sensor (B117) and the transmission module TR2 (A57-2)

3. 3

   The functionality of the transmission module TR2 (A57-2)

1. 1

   Measure the voltage output of the steering angle sensor (B117)

   Use a multimeter to check the voltage at the sensor. Ensure it is within the 0.5V to 4.5V range.

2. 2

   Inspect the wiring and connections

   Check for any loose, damaged, or corroded connections between the steering angle sensor (B117) and the transmission module TR2 (A57-2).

3. 3

   Test the transmission module TR2 (A57-2)

   Verify the operation of the transmission module TR2 (A57-2) to ensure it is correctly interpreting the sensor signal.
