Circuit/System Testing

WARNING: This page is about a different car, the 2008 Buick LaCrosse and 2008 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the EBCM harness connector at the Yaw and Lateral Accelerometer Sensor.
  2. Ignition OFF, with a DMM test for less than 5.0 ohms between the Vehicle Yaw and Lateral Accelerometer Sensor ground circuit terminal 6 and ground.
    • If greater than the specified range, with the DMM test the low reference circuit terminal 6 for an open/high resistance. If the circuit tests normal, replace the EBCM.
  3. Ignition ON, with a DMM test for 0.225-4.775 volts between the Yaw and Lateral Accelerometer Sensor lateral accelerometer signal circuit terminal 5 and ground.
    • If less than the specified range, with the DMM test the lateral accelerometer signal circuit terminal 5 for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM.
    • If greater than the specified range, with the DMM test the lateral accelerometer signal circuit terminal 5 for a short to voltage. If the circuit tests normal, replace the EBCM.
  4. Ignition ON, with a DMM test for 0.225-4.775 volts between the Yaw and Lateral Accelerometer Sensor yaw rate signal circuit terminal 4 and ground.
    • If less than the specified range, with the DMM test the yaw rate signal circuit terminal 4 for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM.
    • If greater than the specified range, with the DMM test the yaw rate signal circuit terminal 4 for a short to voltage. If the circuit tests normal, replace the EBCM.
  5. Ignition ON, with the DMM, test for battery voltage at the Vehicle Yaw and Lateral Accelerometer Sensor Ignition 1 terminal 3 circuit and the ground circuit terminal 6.
    • If less than the specified value, test the ignition circuit terminal 3 for a open/high resistance. If the circuit tests normal, replace the EBCM.
  6. Install a 3A fused jumper wire between the Yaw and Lateral Accelerometer Sensor signal circuit terminal and the Yaw and Lateral Accelerometer Sensor Volt reference circuit terminal 3. With a DMM, verify the voltage range is 2-3 volts.
    • If less than the specified value, test the 5-volt reference circuit terminal 3 for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM.
    • If greater than the specified value, test the 5-volt reference circuit terminal 3 for a short to voltage. If the circuit tests normal, replace the EBCM.
  7. If all circuits test normal, test or replace the Yaw and Lateral Accelerometer Sensor.
