TECHNICAL
Subject:
ABS Warning Light On, Traction Off Warning Light On, DTCs C1223 and C1225 Set (Replace Left Front ABS Wheel Speed Sensor Jumper Harness)
Models:
2003-2004 Chevrolet Cavalier
2003-2004 Pontiac Sunfire
Condition
Some customers may comment that the ABS warning light and/or Traction Off warning light is illuminated. Upon investigation, the technician may find
ABS codes (C1223 - C1225) set as intermittent or hard failures.
Cause
The cause of this condition may be the front wheel speed sensor jumper harness. The harness may check good with the voltmeter, but will not function
correctly when subjected to suspension movement, vibration, and flexing.
Correction
Visually inspect the left front ABS wheel speed sensor harness connector. The wires may become unseated from the connector. This is especially
important on the left side. If the wiring is faulty, replace the harness using the procedure listed below.
1.
Raise and support the vehicle.
2.
Unclip the 3 forward harness routing clips. These clips will be used on the new harness.
3.
Remove the remaining 2 harness routing clips from the control arm. The new harness includes these 2 clips for locating purposes.
4.
Disconnect the wheel speed sensor connector.
5.
Route the new harness into position and install clips.
6.
On the old harness, cut the tape, pull back the conduit, and cut the wire harness to length.
7.
Strip the wire ends, splice the wires using the provided splice clips. Put back in conduit and tape.
8.
Lower the vehicle.
