Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface with the engine off and the parking brake engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace ABS Fuse

Locate the ABS fuse in the fuse box (refer to the owner's manual for the specific location).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace with a new fuse of the same amperage if blown.

3. Inspect and Clean Wheel Speed Sensors

Raise the vehicle and secure it on jack stands.
Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector from each sensor.
Clean the sensor and surrounding area with brake cleaner to remove dirt and debris.
Reconnect the sensors and ensure all connectors are secure.

4. Check Wiring and Connectors

Visually inspect the wiring harness leading to the ABS module for any signs of wear or damage.
Repair or replace any damaged wiring or connectors found during the inspection.

5. Test ABS Control Module

Reconnect the battery terminal.
Use a multimeter to check for voltage at the ABS control module’s power and ground connections.
If no voltage is present, trace the wiring back to the fuse box for any additional issues.
If voltage is present, a replacement of the ABS control module may be necessary.

6. Reassemble and Test

Ensure all components are reassembled correctly.
Test the vehicle by performing a brake system check in a safe environment.
Monitor the ABS light during the test drive to confirm it remains off.
