Circuit/System Testing

WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connectors at the appropriate E1 accent light.
  2. Test for less than 5 Ω between the ground circuit terminal and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition OFF, doors closed, wait 20 seconds before testing for less than 0.3 V between the control circuit terminal and ground.
    • If greater than the specified value, test the circuit for a short to voltage. If the circuits test normal replace the K9 BCM.
  4. Ignition ON, doors open, test for greater than 11 V between the control circuit terminal and ground.
    • If less than the specified value, test the circuit for a short to ground or an open/high resistance. If the circuits test normal replace the K9 BCM.
  5. If all circuits test normal, test or replace the E1 accent light.
