Select the following PIDs and inspect the lateral acceleration and yaw rate.
- LAT_ACCL (lateral acceleration)
- YAW_RATE (yaw rate)
  1. Lateral acceleration inspection
    1. Verify the LAT_ACCL change when the combined sensor is tilted to the left and right.
      - If there is any malfunction, replace the combined sensor. (See COMBINED SENSOR REMOVAL/INSTALLATION .)
    Standard
    
    When the sensor is tilted to the right (A): LAT_ACCL changes positively.

• You smell fuel, burning insulation, or see smoke.
• Brakes feel soft, pull hard to one side, or make grinding noises.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome.
