Circuit/System Testing

WARNING: This page is about a different car, the 2008 GMC Sierra, 2008 GMC Cab & Chassis Sierra, 2008 Chevrolet Silverado, and 2008 Chevrolet Cab & Chassis 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 2 ohm of resistance between the ground terminals 38 and 12 to 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 25 and 13 and ground.
    • If the test lamp does not illuminate, test the B+ circuits for a short to ground or an open/high resistance.
  4. If all circuits test normal, replace the EBCM.
