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 any electrical shorts.

2. Check and Replace ABS Fuse

Locate the fuse box; refer to the owner’s manual for the exact location.
Remove the ABS fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace if blown with a fuse of the same amperage.

3. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors on each wheel hub.
Disconnect the sensor connectors and inspect the wiring for damage.
Clean the sensor area and connector contacts with electrical cleaner.
Reconnect the sensors and ensure they are secured.

4. Test ABS Module and Pump

Reconnect the negative battery terminal.
Using a multimeter, check the voltage and ground at the ABS module.
Activate the ABS pump (if applicable) through the scan tool and listen for operation.
If the pump does not activate, it may need replacement.

5. Clear Error Codes

Using the OBD-II scanner, clear any existing ABS error codes.
Perform a test drive to see if the ABS light reappears.
