Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely jack up the vehicle if needed.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Replace ABS Sensors

Tools Required: Socket set, multimeter
Locate the ABS sensors at each wheel hub.
Disconnect the sensor connector and use a multimeter to test the sensor's resistance.
- If the resistance is out of specification, replace the ABS sensor.
Reconnect the sensor and ensure the wiring is secure and free from damage.

3. Check and Replace Fuses

Tools Required: Fuse puller or pliers
Open the fuse box and locate the ABS fuse.
Remove the fuse and visually inspect it for continuity.
If blown, replace it with a fuse of the same amperage rating.

4. Inspect and Repair Wiring

Tools Required: Wire stripper/crimper, electrical tape
Check for frayed or damaged wiring connected to the ABS module.
Repair or replace any damaged wiring using appropriate connectors and insulation.

5. Refill Brake Fluid

Tools Required: Brake fluid
Check the brake fluid level in the master cylinder reservoir.
If low, refill with the manufacturer-recommended brake fluid type (usually DOT 4).
Inspect for any leaks in the brake system that may have caused fluid loss.

6. Reconnect Battery and Clear Codes

Reconnect the negative terminal of the battery.
Use the OBD-II scanner to clear any ABS error codes.
Start the vehicle and check if the ABS light is off.
