Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect ABS Wheel Speed Sensors

Remove the wheel that corresponds to the ABS warning light (use a jack and jack stands).
Locate the wheel speed sensor, typically mounted near the brake rotor.
Inspect the sensor and its wiring for damage or disconnection.
Clean the sensor and its mounting area to ensure proper function.

3. Check ABS Module and Connections

Locate the ABS control module, usually near the master cylinder.
Inspect the wiring harness for damage or corrosion.
If necessary, remove the module by unbolting it and disconnecting the electrical connectors.
Clean the connectors and reassemble, ensuring a secure fit.

4. Replace Faulty Components (if necessary)

If diagnostic codes indicate a faulty wheel speed sensor or ABS module, replace with OEM parts.
Install new components by reversing the removal process and ensuring proper torque specifications.

5. Reassemble and Reconnect

Reinstall the wheel and tighten lug nuts to the manufacturer’s torque specification.
Reconnect the negative battery terminal.
Clear any fault codes using the OBD-II scanner.
