Solution

1. Preparation

Gather tools and ensure you have a clear workspace.
Disconnect the battery to prevent electrical shorts and ensure safety while working on the vehicle.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any debris or dirt from the sensors and connectors.
Use a multimeter to test the resistance of each sensor; it should typically be within manufacturer specifications.

3. Check Brake Fluid Level

Open the hood and locate the brake master cylinder.
Inspect the brake fluid level; if low, refill with the correct type of brake fluid (usually DOT 3 or DOT 4).
If the fluid is contaminated, flush the brake system and replace with fresh fluid.

4. Examine Traction Control Module

Locate the traction control module, usually near the ABS module.
Inspect the wiring harness for any frays, corrosion, or loose connections.
If damaged, repair or replace the wiring as necessary.

5. Test ABS Functionality

Reconnect the battery and perform a test drive to see if the ABS engages during hard braking.
Use a scan tool to check for any current fault codes that may indicate ABS or traction control issues.
