Circuit/System Testing

WARNING: This page is about a different car, the 2008 Saturn Vue. 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 of resistance between the ground terminal 16 and ground.
    • If greater than the specified range, test the ground circuits for an open/high resistance.
  3. Verify that a test lamp illuminates between the B+ terminals 32 and 1 and ground.
    • If the test lamp does not illuminate, test the B+ circuits for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM.
