Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the battery to prevent electrical shorts.

2. Check Wheel Speed Sensors

Tools Required: Torque wrench, multimeter.
Remove the wheel covering the sensor.
Disconnect the wheel speed sensor connector.
Use a multimeter to measure resistance; refer to the service manual for specifications.
If the sensor is faulty, replace it with a new one and reconnect.

3. Inspect Brake Light Switch

Locate the brake light switch, usually found near the brake pedal.
Check for proper operation by manually engaging the switch and observing if the brake lights illuminate.
If faulty, remove the switch and replace it with a new one.

4. Examine ABS Module

Tools Required: Socket set, torque wrench.
Locate the ABS module, usually found near the brake master cylinder.
Inspect for loose or damaged wiring.
If necessary, remove the module by disconnecting the electrical connectors and bolts.
Replace with a new ABS module if diagnosed as faulty.

5. Verify Tire Condition

Check tire pressure using a tire pressure gauge and inflate to the recommended PSI.
Inspect tread depth to ensure even wear and replace any worn tires.

6. Test Stability Control Switch

Tools Required: Multimeter.
Locate the stability control switch, usually found on the dashboard.
Use a multimeter to check for continuity when the switch is activated.
Replace the switch if it is found to be defective.
