Solution

1. Preparation

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

2. Inspect Wheel Speed Sensors

Tools Required: Multimeter, socket set.
Instructions:
1. Remove the wheels to access the wheel speed sensors.
2. Visually inspect each sensor for any physical damage or debris.
3. Use a multimeter to test the resistance of each sensor; refer to the service manual for specifications.
4. Replace any faulty sensors with OEM parts as necessary.

3. Check Brake System

Tools Required: Brake fluid tester, basic hand tools.
Instructions:
1. Inspect the brake fluid reservoir; ensure the fluid is at the recommended level.
2. If low, top up with the recommended brake fluid type.
3. Look for leaks in brake lines and around calipers; repair or replace as needed.

4. Test Stability Control Module

Tools Required: OBD-II scanner, wiring diagram.
Instructions:
1. Reconnect the battery and turn the ignition on without starting the engine.
2. Use the OBD-II scanner to check for any stored codes related to the stability control system.
3. Follow the diagnostic flowchart in the service manual to isolate any issues with the stability control module.

5. Verify ABS Functionality

Tools Required: Brake system diagnostic tool.
Instructions:
1. Engage the ABS system by performing a controlled stop on a slippery surface to check if the ABS activates.
2. If the ABS does not engage, further diagnose the ABS system as per the manufacturer’s guidelines.
