Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle’s battery to prevent electrical shock.
Allow the vehicle to cool down if it has been recently operated.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors near each wheel hub.
Remove any debris or dirt that may be affecting sensor performance.
If damaged, replace the wheel speed sensors:
- Use a socket set to remove the sensor bolts.
- Disconnect the electrical connector.
- Install the new sensor and reconnect the connector.
- Torque the bolts to manufacturer specifications (typically around 8-10 ft-lbs).

3. Examine and Repair ABS Module

Locate the ABS module, usually near the master cylinder.
Inspect the wiring harness for any frayed or damaged wires.
If a fault is detected, repair or replace the wiring as necessary.
If the ABS module is faulty, replace it:
- Disconnect the battery.
- Remove the mounting bolts and disconnect the electrical connectors.
- Install the new ABS module and reconnect the connectors.
- Torque the bolts to manufacturer specifications.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Ensure the fluid is at the recommended level; top off with the appropriate brake fluid (DOT 3 or DOT 4).
Inspect for any leaks in the brake system.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Remove the switch panel and inspect the switch for any faults.
If faulty, replace the switch:
- Disconnect the electrical connector.
- Remove the switch from the panel.
- Install the new switch and reconnect the electrical connector.
