Solution

1. Preparation

Gather tools and ensure the vehicle is on a flat, stable surface.
Disconnect the battery to prevent electrical issues.

2. Inspect ABS Wheel Speed Sensors

Tools Required: Multimeter, socket set
Sub-steps:
1. Locate the ABS wheel speed sensors at each wheel.
2. Disconnect the electrical connector from each sensor.
3. Use a multimeter to test for resistance; typical values should be between 1,000 to 2,000 ohms.
4. Clean any dirt or debris from the sensor area and reconnect.
5. If any sensor is faulty, replace it.

3. Check and Replace ABS Fuse

Tools Required: Fuse puller or needle-nose pliers
Sub-steps:
1. Locate the fuse box (refer to the owner’s manual for exact location).
2. Identify the ABS fuse and remove it using a fuse puller.
3. Inspect the fuse for continuity; replace it if it is blown (use the same amperage).
4. Reinstall the fuse and ensure it is seated properly.

4. Inspect Wiring and Connectors

Tools Required: Visual inspection tools, multimeter
Sub-steps:
1. Visually inspect the wiring and connectors associated with the ABS module and wheel speed sensors.
2. Look for signs of wear, fraying, or corrosion.
3. Use a multimeter to check for proper voltage at the connectors.
4. Repair or replace any damaged wiring or connectors.

5. Reconnect Battery and Test

Tools Required: None
Sub-steps:
1. Reconnect the battery terminal.
2. Start the vehicle and check if the ABS light remains illuminated.
3. Conduct a test drive to ensure the ABS system functions properly.
