Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Repair Wiring

Tools Required: Wire strippers, electrical tape, multimeter.
Inspect the left rear wheel speed sensor wiring for fraying or damage.
If damaged, repair the wiring by cutting out the damaged section, stripping the ends, and reconnecting with solder or butt connectors.
Wrap repaired sections with electrical tape to prevent future exposure.

3. Replace Wheel Speed Sensor (if necessary)

Tools Required: Socket set, torque wrench, jack and jack stands.

Lift the rear of the vehicle using a jack and secure it with jack stands.
Remove the left rear wheel.
Locate the wheel speed sensor mounted on the brake backing plate.
Disconnect the electrical connector from the sensor.
Remove the retaining bolt(s) holding the sensor in place and carefully pull the sensor out.
Install the new wheel speed sensor in the reverse order of removal, ensuring it is seated properly and secured with the retaining bolt(s).
Reconnect the electrical connector, ensuring it clicks into place.

4. Reassemble and Test

Reinstall the left rear wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer's specifications (usually around 100 ft-lbs).
Start the engine and allow it to idle for a few minutes.
Test drive the vehicle to ensure ABS and traction control systems are functioning properly, and check for any warning lights.
