Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Repair ABS Sensors

Locate the ABS sensors on each wheel hub assembly.
Disconnect the wire harness connectors from the sensors.
Clean the sensor mounting area with brake cleaner to remove any debris.
Inspect the sensors for cracks or damage; replace if necessary.
Reconnect the sensors securely.

3. Check ABS Fuses

Locate the fuse box (refer to the owner's manual for specific location).
Remove the ABS fuse and inspect for continuity using a multimeter.
Replace the fuse with a new one of the same amperage if blown.

4. Brake Fluid Inspection and Replacement

Check the brake fluid level in the master cylinder reservoir.
If low, top off with the recommended brake fluid (DOT 3 or DOT 4, as specified in the owner's manual).
If fluid is contaminated, perform a brake fluid flush:
- Connect a brake bleeder kit to the brake bleeder valve.
- Open the valve and pump fresh brake fluid until clear fluid comes out.
- Repeat for all four wheels.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and monitor the ABS light for illumination.
Test drive the vehicle to ensure proper ABS function.
