Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and securely supported with jack stands.
Disconnect the negative terminal of the battery.

2. Inspect and Replace ABS Wheel Speed Sensors

Tools Required: Socket set, multimeter
Locate the ABS wheel speed sensors at each wheel hub.
Disconnect the electrical connector from each sensor.
Use a multimeter to test the sensor resistance (should be within manufacturer specifications).
If faulty, remove the sensor by unscrewing it from the hub.
Install the new ABS wheel speed sensor and reconnect the electrical connector.

3. Check and Replace ABS Fuse

Tools Required: Fuse puller or pliers
Locate the fuse box (refer to the owner's manual for the specific location).
Identify the ABS fuse and remove it.
Inspect the fuse for continuity; replace if blown with a fuse of the same amperage.
Reinsert the fuse into the fuse box.

4. Inspect Wiring and Connectors

Visually inspect all wiring and connectors leading to the ABS module and wheel speed sensors.
Look for signs of wear, corrosion, or loose connections.
Repair or replace any damaged wiring or connectors as necessary.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Start the vehicle and check if the ABS light is still illuminated.
Conduct a test drive to confirm proper ABS operation.
