Circuit/System Testing

WARNING: This page is about a different car, the 2012 GMC Yukon XL and 2012 Chevrolet Suburban. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the yaw/lateral accelerometer sensor connector.
  2. Ignition OFF and all vehicle systems OFF. It may take up to 2 minutes for all vehicle systems to power down. Test for less than 10 Ω 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 circuits test normal, replace the EBCM.
  3. Ignition ON, test for greater than 10 V between the 12 V reference circuit terminal 1 and ground.
    • If less than the specified range, test the 12 V reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM.
    • If greater than the specified range, test the 12 V reference circuit for a short to voltage. If the circuit tests normal, replace the EBCM.
  4. If all circuits test normal, replace the yaw/lateral accelerometer sensor.
