Circuit/System Testing

WARNING: This page is about a different car, the 2011 Chevrolet Volt. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the S16 Driver Information Center Switch.
  2. Ignition ON, test for 11.8-12.2 V between the 12 V reference circuit terminal 11 and ground.
    • If greater than the specified range, test the 12 V reference circuit for short to voltage. If the circuit tests normal, replace the K9 BCM.
    • 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 K9 BCM.
  3. Verify the scan tool Incandescent Dimming parameter is less than 10%.
    • If greater than the specified range, test the signal circuit terminal 10 for a short to voltage. If the circuit tests normal, replace the K9 BCM.
  4. Install a 3 A fused jumper wire between the signal circuit terminal 10 and the 12 V reference circuit terminal 11. Verify the scan tool Incandescent Dimming parameter is greater than 90%.
    • If less than the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 BCM.
  5. If all circuits test normal, test or replace the S16 Driver Information Center Switch.
