Circuit/System Testing

WARNING: This page is about a different car, the 2008 GMC Yukon and 2008 Chevrolet Tahoe. 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 13
    • Terminal 38
    • 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+ circuit Terminal 1 and ground.
    • 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.
