Circuit/System Testing

WARNING: This page is about a different car, the 2011 GMC Cab & Chassis Sierra, 2011 Chevrolet Suburban, and 2011 Chevrolet Cab & Chassis Silverado. 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.
