Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean ABS Sensors

Locate each ABS wheel speed sensor on all four wheels.
Remove the sensor mounting bolt using a socket set.
Carefully pull the sensor out of its housing and inspect for dirt or debris.
Clean the sensor tip with a soft cloth and a non-corrosive cleaner.
Reinstall the sensor and bolt securely to the specified torque (typically around 7-10 lb-ft).

3. Check and Replace ABS Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers and inspect for a broken filament.
If damaged, replace it with a new fuse of the same amperage.

4. Inspect ABS Control Module Connections

Locate the ABS control module, typically near the master cylinder.
Visually inspect the wiring harness and connectors for damage or corrosion.
Clean the connectors using electrical contact cleaner.
Reconnect securely and ensure all connections are tight.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the ABS light remains off.
Perform a test drive to ensure proper braking function and ABS operation.
