Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues while working on the ABS.

2. Checking and Replacing Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensor mounting screws and disconnect the electrical connector.
Inspect the sensor for dirt or damage; clean or replace as necessary.
Reconnect the sensor and secure it in place with the mounting screws.

3. Inspecting and Repairing ABS Control Module

Locate the ABS control module, usually found near the master cylinder.
Disconnect the electrical connectors and remove any mounting screws.
Check for corrosion or damaged wiring at the connectors.
If necessary, replace the ABS control module according to manufacturer specifications.

4. Brake Fluid Check and Replacement

Open the master cylinder reservoir and check the fluid level.
If the fluid is low, top it up with the recommended brake fluid (DOT 3 or DOT 4).
If the fluid is contaminated, perform a complete brake fluid flush and refill.

5. Testing and Reinstalling Components

Reconnect the battery and start the vehicle.
Check for error codes again; clear any existing codes.
Test drive the vehicle to ensure the ABS functions properly, checking for warning lights or abnormal behavior.
