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 Acceleration Sensor.
  2. Ignition OFF, with a DMM test for less than 5.0 ohms of resistance between the Yaw and Lateral Acceleration Sensor low reference circuit terminal 6 and ground.
    • If greater than the specified range, with the DMM test the low reference terminal 6 circuit for an open/high resistance. If the circuit tests normal, replace the EBCM.
  3. Ignition ON, with a DMM test for 2.1-2.9 volts between the Yaw and Lateral Acceleration Sensor 5-volt reference circuit terminal 1 and ground.
    • If less than the specified range, with the DMM test the 5-volt reference circuit terminal 1 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 5-volt reference circuit terminal 1 for a short to voltage. If the circuit tests normal, replace the EBCM.
  4. With the DMM, verify the Yaw and Lateral Acceleration Sensor signal circuit terminal 4 range is less than 2.1 volts.
    • If greater than the specified value, test the signal circuit terminal 2 for a short to voltage. If the circuit tests normal, replace the EBCM.
  5. Install a 3A fused jumper wire between the Yaw and Lateral Acceleration Sensor signal circuit terminal 2 and the Yaw and Lateral Acceleration Sensor 5-volt reference circuit terminal 3. With a DMM verify the voltage value is greater than 2.9 volts.
    • If less than the specified value, test the signal circuit terminal 2 for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM.
  6. If all circuits test normal, test or replace the Yaw and Lateral Acceleration Sensor.
