Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the yaw and lateral accelerometer sensor.
  2. Ignition OFF, test for less than 10 Ω between the sensor ground circuit terminal and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify that a test lamp illuminates between the sensor ignition circuit terminal and ground.
    • If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM.
  4. Ignition OFF, disconnect the harness connector at the EBCM
  5. Test for less than 1 Ω in each serial data circuit between the yaw and lateral accelerometer sensor and the EBCM.
    • If greater than the specified value, test the yaw and lateral accelerometer sensor serial data circuits for an open/high resistance.
  6. If all circuits test normal, replace the yaw and lateral accelerometer sensor.
