Solution

1. Preparation

• Ensure the vehicle is parked on a flat surface and the ignition is off.
• Gather necessary tools and parts.
• Disconnect the vehicle's battery (negative terminal) to prevent electrical shock.

2. Inspect Wiring and Connectors

• Check the wiring harness connected to the lateral acceleration sensor.
  • Sub-steps:
    • Remove any covers obstructing access to the sensor.
    • Visually inspect for frays, cuts, or corrosion.
    • Clean any corrosion found on connectors with electrical contact cleaner.

3. Test the Lateral Acceleration Sensor

• Use a multimeter to test the sensor.
  • Sub-steps:
    • Disconnect the sensor from the wiring harness.
    • Set the multimeter to the resistance setting and connect probes to the sensor terminals.
    • Compare resistance readings against manufacturer specifications.
    • If the readings are out of spec, replace the sensor.

4. Replace the Lateral Acceleration Sensor (if faulty)

• Remove the old sensor.
  • Sub-steps:
    • Unscrew the mounting bolts using a socket set.
    • Disconnect the electrical connector.
    • Install the new sensor by reversing the removal steps.
