Vertical Acceleration Sensor: Testing and Inspection

1. With component connector still connected, connect voltmeter between terminal 3 (RED/BLK) and ground.
2. Turn ignition switch ON.
3. Tap the chassis acceleration sensor bracket with wrench.
4. Verify that voltage spike (less than 1V) is output from chassis acceleration sensor.
5. If no voltage spike is observed, replace chassis acceleration sensor.
