Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Retrieve and note any ABS-related error codes.
Clear the codes and take the vehicle for a test drive to see if the issue reoccurs.

3. Inspect ABS Components

ABS Wheel Speed Sensors:
- Locate each wheel speed sensor.
- Visually inspect for damage, dirt, or debris.
- Disconnect the sensor connector and check for continuity using a multimeter.
ABS Module:
- Locate the ABS control module.
- Inspect electrical connectors for corrosion or loose connections.

4. Test the ABS Pump

Once the ABS module is accessed, perform a bench test or activate the pump via the OBD-II scanner if supported.
Ensure the pump operates smoothly and does not make unusual noises.

5. Check Brake Fluid

Open the master cylinder reservoir and check the brake fluid level.
If low, top up with manufacturer-recommended brake fluid.
Inspect for any leaks in the brake lines or around the master cylinder.

6. Reassemble and Test

Reconnect all sensors and modules.
Reassemble any components removed during inspection.
Torque all bolts to the manufacturer's specifications.
Perform a test drive to confirm the ABS light does not reappear.
