Circuit/System Testing

WARNING: This page is about a different car, the 2008 Pontiac Torrent and 2008 Chevrolet Equinox. 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 ohm of resistance between the ground circuit terminal 16 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 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 ABS motor 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 no 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, on the EBCM side.
  8. Ignition ON, use the scan tool to perform the Pump Motor Test.
    • If test lamp does not illuminate, replace the EBCM. If the DTC continues to set, replace the BPMV.
  9. If all circuits test normal, replace the BPMV.
