Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent any electrical issues during repair.

2. Inspect and Clean ABS Wheel Speed Sensors

Tools Required: Socket set, cleaning brush, and brake cleaner.
Remove the wheel to access the ABS sensor.
Inspect the sensor for dirt or debris; clean using brake cleaner and a brush.
Reinstall the sensor and ensure it is securely connected.

3. Check and Replace Brake Fluid

Tools Required: Brake fluid, fluid transfer tool.
Inspect the brake fluid reservoir. If the fluid is low or contaminated, drain the old fluid using a fluid transfer tool.
Replace with manufacturer-recommended brake fluid (e.g., DOT 3 or DOT 4).
Bleed the brake lines to remove any air bubbles.

4. Inspect ABS Module and Pump

Tools Required: Multimeter, socket set.
Locate the ABS module under the hood.
Check for any visible leaks or damage to the module.
Using a multimeter, test the power and ground connections to the ABS pump.
Replace the module if a fault is detected.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal after all repairs are complete.
Use an OBD-II scanner to clear any ABS error codes from the system.
Perform a test drive to ensure the ABS light does not reappear.
