Diagnostic Trouble
Code Description
Repair Information
1 Excessive Air Gap Adjust sensor to contact exciter ring. Rotate wheel and verify a minimum
of 0.25 VAC sensor output at ~ 0.5 RPS. Verify condition of sensor head.
Verify mounting of exciter ring and condition of teeth. Verify proper bearing
end-play. Verify condition and retention of clamping sleeve. Verify sensor
lead routing and clamping.
2 Output Low at
Drive-off
Adjust sensor to contact exciter ring. Rotate wheel and verify a minimum
of 0.25 VAC sensor output at ~ 0.5 RPS. Verify condition of sensor head.
Verify mounting of exciter ring and condition of teeth. Verify proper bearing
end-play. Verify condition and retention of clamping sleeve. Verify sensor
lead routing and clamping.
3 Open or Shorted Verify 1500 – 2500 ohms across sensor leads. Verify no continuity between
sensor leads and ground or voltage. Verify no continuity between sensor
leads and other sensors. Check for corroded/damaged wiring or connectors
between the ECU and the wheel speed sensor.
4 Loss of Sensor
Signal
Adjust sensor to contact exciter ring. Rotate wheel and verify a minimum
of 0.25 VAC sensor output at ~ 0.5 RPS. Verify condition of sensor head.
Verify mounting of exciter ring and condition of teeth. Verify proper bearing
end-play. Verify condition and retention of clamping sleeve. Verify sensor
lead routing and clamping. Check for corroded/damaged wiring or connectors
between the ECU and the wheel speed sensor.
5 Wheel End Verify mounting of exciter ring and condition of teeth. Verify proper bearing
end-play. Verify condition and retention of clamping sleeve. Verify sensor
lead routing and clamping. Check mechanical function of brake. Check for
kinked or restricted air lines.
6 Erratic Sensor
Signal
Adjust sensor to contact exciter ring. Rotate wheel and verify a minimum
of 0.25 VAC sensor output at ~ 0.5 RPS. Verify condition of sensor head.
Verify mounting of exciter ring and condition of teeth. Verify proper bearing
end-play. Verify condition and retention of clamping sleeve. Verify sensor
lead routing and clamping. Check for corroded/damaged wiring or connectors
between the ECU and the wheel speed sensor.
7 Tire Size
Calibration
Verify correct tire size as desired. Verify proper tire inflation. Verify correct
number of exciter ring teeth.
10 Configuration
Error
ECU is configured for four sensors, but has detected the presence of
additional sensors. Verify sensor wiring and ECU configuration.
