Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a flat surface and secured with wheel chocks.

2. Inspect and Clean Connections

Locate the ABS control module and disconnect the wiring harness.
Inspect the connectors for corrosion or damage; clean them with an electrical contact cleaner.
Reconnect the wiring harness securely.

3. Check Wheel Speed Sensors

Raise the vehicle and remove the front and rear wheels for access.
Disconnect the wheel speed sensor connectors at each wheel.
Inspect each sensor for damage, dirt, or debris; clean as necessary.
Use a multimeter to check sensor resistance (specification should be around 1,000-1,500 ohms).

4. Test and Replace ABS Module (if necessary)

If issues persist after cleaning, test the ABS module using a multimeter or scan tool.
If the module is faulty, remove it by unscrewing any mounting bolts and disconnecting the hydraulic lines (be prepared for fluid loss).
Install the new ABS module, ensuring all connections are secure and correctly torqued to manufacturer specifications.

5. Final Steps

Reconnect the negative battery terminal.
Clear all error codes using an OBD-II scanner.
Perform a test drive to verify that the ABS system functions properly and that the warning lights do not reappear.
