Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Repair ABS Sensors

Locate the ABS sensors at each wheel hub.
Sub-steps:
- Remove the wheel to access the sensor.
- Disconnect the sensor wiring harness.
- Clean the sensor and mounting area with brake cleaner.
- Reconnect the sensor and ensure it is securely fastened.
- Repeat for all wheel sensors if necessary.

3. Replace Faulty ABS Module

If diagnostic codes indicate a faulty ABS module, replacement may be necessary.
Sub-steps:
- Remove any components obstructing access to the ABS module (such as air intake ducts).
- Disconnect the wiring harness from the old ABS module.
- Unbolt the module from its mounting location.
- Install the new ABS module by reversing the removal steps.
- Ensure all connections are secure.

4. Refill and Bleed Brake System

After sensor or module repair, check brake fluid levels.
Sub-steps:
- Refill the brake fluid reservoir with the manufacturer's recommended fluid type.
- Bleed the brake lines to remove any air pockets using a brake bleeder kit.
- Start with the wheel farthest from the master cylinder and work towards the nearest.

5. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Start the vehicle and check for ABS light status.
Sub-steps:
- Perform a short test drive to verify proper ABS operation and ensure the warning light does not reappear.
