Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is on a level surface and securely supported.
Disconnect the battery to avoid electrical shorts.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Locate each wheel speed sensor at each wheel hub.
Remove the sensor bolts using the socket set.
Clean any debris from the sensor area and inspect the sensor and wiring for damage.
Use a multimeter to check the sensor resistance; it should typically be between 800 to 1,500 ohms.
If a sensor is faulty, replace with an OEM part.

3. Check ABS Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box and identify the ABS fuse based on the diagram.
Remove the fuse and inspect it for continuity; replace if blown.
Reinstall the new fuse and ensure it fits securely.

4. Examine Brake Fluid

Tools Required: Brake fluid tester (optional), clean cloth
Check the brake fluid reservoir for proper fluid level.
Inspect the fluid for contamination or discoloration; if necessary, bleed the brakes and refill with the correct DOT fluid as specified in the owner's manual.

5. Inspect ABS Module Wiring

Tools Required: Visual inspection tools, multimeter
Follow the wiring harness from the ABS module to the connectors.
Check for any loose, corroded, or damaged connections.
Use a multimeter to check for continuity in the wiring; repair or replace damaged sections as needed.

6. Test ABS Module

Tools Required: Diagnostic scan tool
Using a compatible scanner, access the ABS module and run diagnostic tests.
Follow on-screen prompts to complete the test and address any faults indicated.
