Solution

1. Preparation

Gather tools including an OBD-II scanner, multimeter, socket set, and brake fluid.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the wheel speed sensors.
3. Inspect the sensor wiring for damage or corrosion.
4. Clean the sensor and mounting area using brake cleaner.
5. Reconnect any loose or damaged connections.

3. Check ABS Module and Pump

Sub-steps:
1. Locate the ABS module, typically near the master cylinder.
2. Inspect the electrical connectors for corrosion or damage.
3. Use a multimeter to check the voltage supply to the ABS pump.
4. If necessary, replace the ABS module, ensuring to torque bolts to manufacturer’s specifications (typically around 89-106 in-lbs, but check specific manual).

4. Brake Fluid and System Check

Sub-steps:
1. Check the brake fluid reservoir for proper fluid level.
2. If low, top off with manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
3. Inspect brake lines for leaks or signs of wear.
4. If leaks are found, replace damaged brake lines and bleed the brake system.

5. Clear Error Codes

Sub-steps:
1. Reconnect the negative battery terminal.
2. Use the OBD-II scanner to clear any stored error codes from the ABS system.
3. Perform a test drive to ensure the ABS light does not return.
