Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replace ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the wheel (if required) to access the sensor.
Disconnect the sensor wiring harness.
Use a multimeter to test the sensor for proper resistance; replace if it’s out of spec.
Install the new sensor by reversing the removal steps and torque to manufacturer specifications (typically around 7-12 lb-ft).

3. Inspect and Repair Wiring

Visually inspect the wiring harness for any signs of wear or damage.
If damaged, repair the wiring using appropriate automotive splice techniques.
Use heat-shrink tubing or electrical tape to protect repaired areas.

4. Brake Fluid Check and Replacement

Inspect the brake fluid reservoir; if low, top it off with the recommended brake fluid (DOT 3 or DOT 4).
If the fluid is contaminated, completely flush the brake system and replace with new fluid.
Bleed the brake system to remove any air pockets.

5. Reconnect Battery and Reset ABS Module

Reconnect the battery and clear any stored codes using the OBD-II scanner.
Test drive the vehicle to ensure the ABS light remains off and the system functions correctly.
