Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery to ensure safety.

2. Inspect ABS Fuses

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the ABS fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace if blown.
Reinsert the fuse and reconnect the battery terminal.

3. Check Brake Fluid Level

Locate the master cylinder reservoir.
Ensure the brake fluid level is between the minimum and maximum marks.
If low, top off with the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).

4. Inspect ABS Wheel Sensors

Lift the vehicle securely using jack stands.
Locate each wheel speed sensor on the brake assembly.
Inspect the sensor for physical damage or dirt buildup.
Clean the sensor if necessary and ensure it is securely connected.

5. Test Wheel Speed Sensors

Using a multimeter, set it to the resistance setting.
Disconnect the sensor's electrical connector.
Measure the resistance across the sensor terminals; compare with specifications in the repair manual.
Replace any faulty sensors as needed.

6. Clear Error Codes

Reconnect the OBD-II scanner to the diagnostic port.
Clear any stored ABS error codes.
Re-test the vehicle to check if the ABS light remains off.
