Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, brake fluid, cleaning supplies.
Gather all necessary tools and parts before starting the repair.
Make sure the vehicle is parked on a level surface and the engine is off.
Safety Warnings: Disconnect the battery to prevent electrical shock or shorts.

2. Address Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Clear any existing fault codes related to the ABS system.
Reconnect the battery and turn on the ignition to check if the ABS light remains off.

3. Inspect and Replace ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove the sensor mounting bolts using a socket set.
Carefully remove the sensor and inspect for dirt or damage.
If damaged, replace the sensor with a new one.
Reinstall the sensors, ensuring they are securely mounted and connected.

4. Check and Replace Brake Fluid

Locate the brake fluid reservoir and check the fluid level.
If the fluid is low, top it off with the manufacturer-recommended brake fluid.
If the fluid appears dirty or contaminated, flush the brake system and replace with fresh fluid.
Bleed the brake lines to remove air from the system.

5. Inspect Wiring and Connectors

Visually inspect the wiring and connectors associated with the ABS system.
Look for any signs of wear, fraying, or corrosion.
Clean any corroded connectors and ensure they are securely connected.
Replace any damaged wiring or connectors as necessary.
