Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Scan for Error Codes

Use an OBD-II scanner to retrieve ABS-related trouble codes.
Document any codes for further analysis.

3. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, torque wrench, multimeter
Remove the wheel to access the wheel speed sensor.
Disconnect the sensor connector and remove the mounting bolts.
Inspect the sensor for damage or buildup of debris.
If faulty, install a new wheel speed sensor, torque bolts to manufacturer's specifications, and reconnect the electrical connector.

4. Check ABS Module and Wiring

Inspect the ABS module for loose connections or corrosion.
Use a multimeter to test the electrical connections for continuity.
If issues are found, repair or replace the wiring as needed.

5. Brake Fluid Check

Remove the cap from the master cylinder reservoir.
Check the brake fluid level; if low, top off with the recommended brake fluid type (DOT 3 or DOT 4 as specified).
Inspect for leaks around the master cylinder and brake lines.

6. Reset ABS Light
