Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted with jack stands.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel and tire for access.
Visually inspect each wheel speed sensor for breakage or loose connections.
Use a multimeter to test each sensor's resistance; compare readings to manufacturer specifications.
Clean sensors if dirty and reassemble. Replace if faulty.

3. Check ABS Fuse

Tools Required: Fuse puller or pliers
Locate the fuse box (refer to the owner's manual for exact location).
Remove the ABS fuse and visually check for signs of damage (burnt or broken).
If blown, replace with a fuse of the same amperage rating.

4. Inspect ABS Control Module

Tools Required: Socket set, torque wrench
Find the ABS control module (typically near the brake master cylinder).
Disconnect the electrical connectors.
Inspect for any signs of corrosion or loose connections.
Reconnect and secure all connectors; replace the module if damaged.

5. Test Drive and Reset

Tools Required: OBD-II scanner
Reconnect the negative battery terminal.
Start the vehicle and use the OBD-II scanner to clear any ABS error codes.
Conduct a test drive to ensure the ABS light remains off and brakes function properly.
