Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Fault Codes

Reconnect the battery.
Use the OBD-II scanner to clear any fault codes.
If the ABS light remains on, proceed with specific repairs based on the codes retrieved.

3. Inspect and Replace Wheel Speed Sensors (if needed)

Tools Required: Socket set, multimeter, wire brush
Locate the ABS wheel speed sensors at each wheel hub.
Disconnect the electrical connector from the sensor.
Remove the sensor using the socket set and inspect for damage or corrosion.
Clean the mounting area with a wire brush. If the sensor is damaged, replace it with a new one.
Reinstall the sensor, reconnect the electrical connector, and ensure it is secure.

4. Check and Replace Fuses

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box and identify the ABS fuses (refer to the owner's manual for the exact location).
Remove the fuses and inspect them for continuity. Replace any blown fuses with new ones of the same amperage.

5. Inspect and Top Up Brake Fluid

Check the brake fluid reservoir for proper fluid level.
If low, top up with the recommended brake fluid type as specified in the owner’s manual.
Inspect for any leaks in the brake lines or around the master cylinder.

6. Test ABS Control Module

Tools Required: Multimeter
Inspect the wiring harness connected to the ABS control module for any visible damage.
Use the multimeter to check for proper voltage and ground at the module.
If issues are found with the module, it may require reprogramming or replacement.
