Circuit/System Testing

WARNING: This page is about a different car, the 2013 GMC Acadia, 2013 Chevrolet Traverse, and 2013 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

If equipped, the following tests can be performed at an inline connector. See schematics for the corresponding terminals to test at.

  1. Ignition OFF, disconnect the harness connector at the fuel level sensor.
  2. Ignition ON, verify that the scan tool fuel tank level remaining parameter is less than 4 percent.
    • If greater than the specified value, test the signal circuit terminal D for a short to ground. If the circuit tests normal, replace the ECM.
  3. If all circuits test normal, test or replace the fuel level sensor.
