Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools, jack and jack stands, wheel chocks.
Ensure the vehicle is parked on a level surface and the engine is off. Disconnect the battery to prevent any electrical shorts.

2. Inspect Wheel Speed Sensors

Sub-steps:
- Lift the front and rear of the vehicle using a jack and secure it with jack stands.
- Remove the wheel to access the wheel speed sensors.
- Visually inspect each sensor for physical damage or corrosion.
- Disconnect the sensor connectors and clean them if necessary.
- Use a multimeter to check the sensor resistance; it should typically be between 1000-2000 ohms. Replace any faulty sensors.

3. Check Stability Control Module and Connections

Sub-steps:
- Locate the stability control module, usually situated near the ABS module.
- Inspect the wiring harness and connectors for signs of wear, fraying, or corrosion.
- Clean the connectors and reseat them to ensure a solid electrical connection.
- If error codes indicate a module failure, consider replacing the stability control module.

4. Inspect Brake Pressure Sensor

Sub-steps:
- Locate the brake pressure sensor, typically near the master cylinder.
- Disconnect the sensor and check for continuity using a multimeter.
- If readings are outside the manufacturer's specifications, replace the sensor.

5. Tire and Alignment Check

Sub-steps:
- Inspect all tires for proper inflation and tread wear.
- Ensure that all tires match in size and are equally inflated according to manufacturer specifications.
- If necessary, perform a wheel alignment to ensure proper handling and stability.
