Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector of the yaw and lateral accelerometer sensor.
  2. Ignition OFF, test for less than 5 Ω between the sensor ground circuit and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance. If the circuit tests normal, replace the EBCM.
  3. Ignition ON, verify that a test lamp illuminates between the sensor B+ circuit and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM.
  4. Test the serial data circuits for an short to ground, open/high resistance, or short to voltage. If all circuits test normal, replace the yaw and lateral accelerometer sensor.
