1. 1

   Verify the 8.5 VDC power supply to the sensor at the microfuse PCB (A013), fuse 17.

2. 2

   Inspect the wiring harness and the separation point connector X1509 for damage or poor connection.

3. 3

   Check the left front axle on top of the axle suspension for physical damage to the sensor or the steering cylinder protective cover.

4. 4

   Look for secondary codes (e.g., 15.1.6C, 15.1.6D, 15.1.6E) that might indicate a calibration issue rather than a hard failure.
