Circuit/System Testing

  1. Ignition OFF, disconnect the yaw rate sensor/lateral accelerometer connector.
  2. Test for less than 1 ohm of resistance between the low reference circuit and ground.
    • If greater than 1 ohm, test the low reference circuit and the EBCM ground circuit for an open/high resistance. If the circuits test normal, replace the EBCM.
  3. Test the yaw rate signal circuit, the 5-volt reference circuit, for an open/high resistance or a short to voltage or ground.
    • If all circuits test normal, replace the yaw rate sensor/lateral accelerometer, and clear the yaw rate sensor DTCs in the EBCM.
    • If the DTC sets again after replacing the yaw rate sensor/lateral accelerometer, replace the EBCM.
  4. Test for infinite resistance between the yaw rate frequency circuit and ground.
    • If less than infinite resistance, test the yaw rate frequency circuit for a short to ground.
  5. Test for less than 1 ohm of resistance on the yaw rate frequency circuit between the yaw rate sensor connector, and EBCM connector.
    • If greater than 1 ohm, test the yaw rate frequency circuit for an open/high resistance or short to voltage.
    • If all circuits test normal, replace the yaw rate sensor/lateral accelerometer, and clear the yaw rate sensor DTCs in the EBCM.
    • If the DTC sets again after replacing the yaw rate sensor/lateral accelerometer, replace the EBCM.
  6. Test for infinite resistance between the yaw rate sensor self test signal circuit and ground.
    • If less than infinite resistance, test the yaw rate sensor self test circuit for a short to ground.
  7. Test for less than 1 ohm of resistance on the yaw rate sensor self test circuit between the yaw rate sensor connector, and EBCM connector.
    • If greater than 1 ohm, test the yaw rate sensor self test circuit for an open/high resistance or short to voltage.
    • If all circuits test normal, replace the yaw rate sensor/lateral accelerometer, and clear the yaw rate sensor DTCs in the EBCM.
    • If the DTC sets again after replacing the yaw rate sensor/lateral accelerometer, replace the EBCM.
