Circuit/System Testing

WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. 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 5 ohms between the ground circuit terminal 26 and ground.
    • 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 14 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, test or replace the BPMV.
  4. Ignition OFF, remove the EBCM from the BPMV.
  5. Inspect the EBCM to BPMV connector for conditions such as damage, corrosion, or presence of brake fluid.
    • If connector corrosion or damage is evident, replace BPMV and/or EBCM as necessary.
    • If brake fluid is present, replace both BPMV and EBCM.
  6. Connect the EBCM harness connector with the BPMV still separated.
  7. Connect a test lamp between the pump motor circuits terminals.
  8. Command the Pump Motor Test with a scan tool, the test lamp should illuminate when commanded.
    • If test lamp does not illuminate, replace the EBCM. If the DTC resets, replace the BPMV.
  9. If all circuits test normal, replace the BPMV.
