Circuit/System Testing
WARNING: This page is about a different car, the 2009 Saturn Outlook, 2009 GMC Acadia, 2009 Chevrolet Traverse, and 2009 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.
- Test for less than 2.0 ohms between the ground circuits terminal 4 of the DLC and ground, and terminal 5 of the DLC and ground.
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Ignition ON, verify a test lamp illuminates between the B+ circuit terminal 16 at the DLC and ground.
- If the test lamp does not illuminate, test the voltage supply circuit for a short to ground or an open/high resistance.
- If all circuits test normal, refer to the scan tool/CANdi module user guide.
