Circuit/System Testing

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2007 GMC Savana Special, 2007 GMC Savana Camper Special, 2007 GMC Savana, 2007 Chevrolet RV Cutaway, and 2007 Chevrolet Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
  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.
