Solution

1. Preparation

Gather necessary tools and parts for the repair.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the battery to prevent electrical shock.

2. Check and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean rags
Remove the cap from the master cylinder reservoir.
If the fluid is low, top it up with the appropriate type of brake fluid (usually DOT 3 or DOT 4).
Replace the cap securely once finished.

3. Inspect and Clean ABS Wheel Speed Sensors

Tools Required: Socket set, cleaning brush, isopropyl alcohol
Lift the vehicle and remove the wheel to access the ABS sensor.
Disconnect the wiring harness from the ABS sensor.
Remove the sensor from its mounting location.
Clean the sensor and the mounting area with a cleaning brush and isopropyl alcohol.
Reinstall the sensor and reconnect the wiring harness.

4. Replace Faulty ABS Fuse

Tools Required: Fuse puller or pliers
Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the fuse using the fuse puller and inspect it for continuity.
Replace with a new fuse of the same amperage if blown.

5. Reconnect Battery and Test

Reconnect the vehicle’s battery.
Start the vehicle and check if the ABS light remains on.
If the light is off, the issue may be resolved. If it persists, further investigation of the ABS module may be necessary.
