Condition
Some customers may comment that the Antilock Brake System (ABS), Traction Control System (TCS) or StabiliTrak(R) (if equipped) warning lights are
illuminated. Upon investigation, one or more of the following DTCs may be in history or current.
Correction
Begin diagnostics with the component test procedure listed below. If the cause is not found, proceed to the Circuit/System Testing on the applicable
Diagnostic Information and Procedures document for the vehicle you are working on. SI Diagnostic Information and Procedures are being revised to
reflect this change in strategy.
1.
With the ignition OFF, disconnect the harness connector at the appropriate wheel speed sensor.
2.
Test for 850-1350 ohms between the signal terminal A and the low reference signal terminal B. During the test, check for an intermittent circuit
condition by gently moving the wheel speed sensor pigtail harness. If not within the specified range, replace the wheel speed sensor.
