Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (screwdrivers, wrenches), torque wrench, vehicle lift/jack stands.
Disconnect the vehicle battery to ensure safety while working on electronic components.

2. Wheel Speed Sensor Inspection

Sub-steps:
1. Raise the vehicle and remove the wheels to access the wheel speed sensors.
2. Inspect each sensor for physical damage or dirt accumulation.
3. Clean the sensors with an appropriate automotive cleaner if necessary.
4. Reinstall the wheels and lower the vehicle.

3. ABS Module Check

Sub-steps:
1. Locate the ABS module, usually found near the brake master cylinder.
2. Inspect the module for any visible damage or leaks.
3. Use the OBD-II scanner to check for any ABS-related fault codes.
4. If codes indicate a module failure, replace the ABS module following specific manufacturer guidelines.

4. Wiring and Connector Examination

Sub-steps:
1. Trace the wiring harness leading to the ABS module and wheel speed sensors.
2. Look for frayed wires, corrosion, or loose connectors.
3. Repair or replace any damaged wiring or connectors as necessary.

5. Steering Angle Sensor Testing

Sub-steps:
1. Locate the steering angle sensor, typically mounted on the steering column.
2. Using a multimeter, measure the output voltage while turning the steering wheel to ensure it varies appropriately.
3. If the sensor output is not within specifications, replace the steering angle sensor.

6. Final Assembly and Testing

Sub-steps:
1. Reconnect the vehicle battery.
2. Clear any fault codes using the OBD-II scanner.
3. Perform a road test to ensure stability control operates correctly and the warning light does not reappear.
