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

Tools Required: Socket set, multimeter, cleaning brush
Remove the wheel to access the ABS sensor.
Disconnect the ABS sensor connector.
Use a multimeter to check the resistance of the sensor (should typically be between 1,000 to 2,000 ohms).
Clean the sensor and the mounting area with a soft brush to remove any debris.
Reconnect the sensor and reinstall the wheel.

3. Check ABS Module and Pump

Tools Required: Multimeter, OBD-II scanner
Reconnect the battery terminal.
Use the OBD-II scanner to check for any active codes related to the ABS module.
If codes indicate a malfunction in the ABS module, consider replacing the module.
If the pump is faulty, it may need to be replaced. Disconnect the electrical connector and fluid lines, then remove the pump from its mounting.

4. Inspect Wiring and Connectors

Tools Required: Visual inspection tools, multimeter
Visually inspect all wiring and connectors related to the ABS system for corrosion, damage, or loose connections.
Use a multimeter to check for continuity in the wiring harness.

5. Test Drive and Monitor

Tools Required: OBD-II scanner
Once repairs are made, take the vehicle for a test drive to verify the ABS light does not reappear.
Check for any DTCs again using the OBD-II scanner after the drive.
