Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal.

2. Check and Replace ABS Fuse

Locate the fuse box and identify the ABS fuse using the diagram on the cover.
Use a multimeter to check for continuity in the ABS fuse.
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Inspect Wheel Speed Sensors

Raise the vehicle and secure it on jack stands.
Locate the wheel speed sensors at each wheel hub.
Disconnect the sensor harness and clean the sensor with a cloth.
Inspect the sensor and wiring for any signs of damage; replace any damaged components.

4. Examine ABS Module and Pump

Locate the ABS module and pump assembly, usually near the master cylinder.
Visually inspect for leaks, corrosion, or physical damage.
If any issues are found, replace the ABS module or pump as necessary.

5. Verify Brake Fluid Condition

Check the brake fluid reservoir for proper fluid level.
If the fluid is low, top it off with the recommended brake fluid type (DOT 3 or DOT 4).
If the fluid is dirty or contaminated, perform a brake fluid flush and replace it.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and observe the ABS light; it should turn off if the issue is resolved.
Perform a test drive to ensure the ABS system functions correctly.
