Circuit/System Testing

WARNING: This page is about a different car, the 2009 GMC Sierra and 2009 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the EBCM.
  2. Test for less than 1 ohm between the ground circuits listed below and ground:
    • Terminal 38
    • Terminal 13
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify that a test lamp illuminates between the B+ circuits listed below and ground:
    • Terminal 25
    • Terminal 1
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal and the B+ circuit fuse is open, replace the BPMV.
  4. If all circuits test normal, replace the BPMV and verify DTC does not reset. If the DTC resets replace the EBCM.
