Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical short circuits.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter, cleaning brush.
Remove the wheel from the affected corner.
Locate the wheel speed sensor and disconnect the electrical connector.
Use a multimeter to check for proper voltage output (typically around 0.5 - 1.0 volts when rotating the wheel).
Clean any debris or corrosion from the sensor and mounting area.
Reattach the connector and wheel.

3. Check ABS Module

Tools Required: Torque wrench, socket set.
Locate the ABS module under the hood.
Inspect wiring harness for damage or corrosion.
If needed, remove the ABS module bolts and disconnect the wiring carefully.
Install a replacement module if diagnostics indicate failure.
Reinstall and torque the bolts to manufacturer specifications.

4. Brake Fluid and Lines Inspection

Tools Required: Brake fluid container, wrench set.
Check the brake fluid reservoir; add fluid as necessary (use DOT 3 or DOT 4 fluid as specified).
Inspect brake lines for leaks or damage; repair or replace as necessary.

5. Reconnect Battery and Test

Reconnect the negative battery terminal securely.
Start the vehicle and check if the ABS light has turned off.
If the light remains on, further diagnostics may be needed.
