Solution

1. Preparation

Gather tools and safety equipment.
Disconnect the negative battery terminal to avoid electrical shorts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Inspect ABS Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel and tire to access the wheel speed sensor.
Disconnect the sensor wiring harness.
Use a multimeter to test the sensor resistance; refer to your vehicle’s service manual for the specific range.
If the sensor is faulty, proceed to replace it.

3. Check ABS Fuses and Relays

Tools Required: Fuse puller, multimeter
Locate the fuse box as indicated in the owner’s manual.
Remove the ABS fuse and inspect it for continuity using a multimeter.
If the fuse is blown, replace it with one of the same amperage.
Test the ABS relay by swapping it with a similar relay in the fuse box to see if the issue resolves.

4. Repair Wiring and Connectors

Inspect the wiring harness connected to the ABS system.
Look for frayed wires, corrosion, or loose connections.
Repair any damaged wiring by splicing in new wire segments or replacing connectors.
Reconnect all wiring securely.

5. Replace Brake Fluid (if needed)

Tools Required: Brake fluid, brake bleeder kit
Check the brake fluid reservoir for contamination or low levels.
If necessary, drain the old brake fluid and replace it with fresh fluid that meets manufacturer specifications.
Bleed the brake lines to remove any air from the system.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored ABS codes.
Perform a test drive to ensure the ABS light does not reappear.
