Circuit/System Testing

WARNING: This page is about a different car, the 2008 Chevrolet HHR. However, it is still accessible from the selected car via links, so may be relevant.
  1. Verify that a test lamp illuminates between the SDM or XM/ONSTAR fuse 24 in the BCM and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  2. Ignition OFF, disconnect the harness connectors at the BCM.
  3. Ignition OFF, test for less than 5 ohms of resistance between the ground circuit terminal E12 X4 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  4. Verify that a test lamp illuminates between the B+ circuit terminals listed below and ground.
    • Terminal D1 X3
    • Terminal D12 X3
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  5. If all circuits tests normal, replace the BCM.
