VCM’s screen.
A. The steering angle jumps up and down in value:
• Check the sensor’s air gap by following the pro-
cedures described in Chapter 4: Steering.
• Check for steering yokes ability to move in and
out of the axle casting.
NOTE: Travel of the left yoke will cause the magnet
to move in and out of the steering sensors
range.
• Verify that the steering sensor is parallel to the
magnet and that the two shim washers are
present under the steering sensor bracket.
• Sensor is not centered over the magnet.
B. The steering angle jumps from one end of the scale to the other:
• The magnet is out of alignment.
• Sensor is not centered over the magnet.
• The sensor is calibrated backwards.
