Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the vehicle to cool if brake components have been recently used.

2. Inspect and Repair Wiring

Tools Required: Multimeter, wire stripper/crimping tool
Check the wiring harness connected to the ABS module for any fraying or breaks.
Use a multimeter to test for continuity in the wiring.
Repair any damaged wires by stripping and crimping new connectors or using solder.

3. Replace Wheel Speed Sensors (if necessary)

Tools Required: Ratchet and socket set, torque wrench
Raise the vehicle and remove the wheel for better access.
Disconnect the electrical connector from the wheel speed sensor.
Remove the sensor from the hub assembly by unscrewing it.
Install the new wheel speed sensor and torque to manufacturer specifications.
Reconnect the electrical connector and reinstall the wheel.

4. Check Brake Fluid Level

Tools Required: Brake fluid tester (if contamination is suspected)
Remove the brake fluid reservoir cap.
Check the fluid level and ensure it is at the recommended level.
If the fluid is contaminated, drain the reservoir and replace it with new brake fluid (DOT 3 or DOT 4 as specified by manufacturer).

5. Reset ABS Light

Tools Required: OBD-II scanner
After repairs, use the OBD-II scanner to clear any ABS fault codes.
Reconnect the negative battery terminal.
Start the vehicle and check if the ABS light is off.
