Circuit/System Testing

WARNING: This page is about a different car, the 2008 Isuzu Ascender, 2008 GMC Envoy, and 2008 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the yaw-rate/lateral accelerometer connector.
  2. Test the yaw-rate/lateral sensor reference voltage circuit for a short to voltage, short to ground, an open or high resistance.
    • If the reference voltage circuit did not test normal, repair the circuit.
  3. Test the yaw/lateral sensor ground circuit for an open or high resistance.
    • If the reference ground circuit did not tests normal, repair the circuit.
  4. Test the yaw/lateral sensor CAN HI and LO circuit for a short to voltage, short to ground, an open or high resistance.
    • If the yaw/lateral CAN HI and LO circuits did not test normal repair the circuit.
  5. Ignition ON, test the yaw/lateral sensor reference voltage circuit for 5 volts, and the ground circuit for an open or high resistance.
    • If the yaw/lateral 5 volt reference and ground circuits test normal replace the yaw/lateral sensor.
