Circuit/System Testing

WARNING: This page is about a different car, the 2008 GMC Yukon and 2008 Chevrolet Tahoe. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the yaw and lateral accelerometer sensor.
  2. Ignition OFF, test for less than 5.0 ohm between the low reference circuit terminal 6 and ground.
    • If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the EBCM.
  3. Ignition ON, test for B+ between the ignition circuit terminal 1 and ground.
    • If less than the specified range, test the ignition circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM.
  4. If the circuits test normal, replace the yaw and lateral accelerometer sensor.
