Condition

Some owners may comment that the ABS indicator lamp is "ON". Also, malfunction DTC 21, 22, 32 or 33 could set.

Cause

The right front and left front ABS wheel speed sensor wiring harness could be damaged and result in an open circuit. The wiring harness may be damaged approximately 4 inches (10 cm) back from the harness connector to the wheel speed sensor. This allows moisture to enter the harness causing corrosion and resulting in the open circuit.

Correction

A thorough inspection for corrosion and/or damage should be performed on suspect vehicles. It may be necessary to move the protective conduit away in order to inspect the wiring properly. If a failure occurs and damage is found, install the front ABS wheel speed sensor wiring harness connector kit(s). The kit includes instructions, splices, and "pigtail" connector.
