Diagnostic Test

INTERMITTENT DTC 

1. The conditions necessary to set this DTC are not present at this time.
2. Review the scan tool environmental data. If possible, try to duplicate the conditions under which the DTC set.
3. If applicable, actuate the component with the scan tool.
4. Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors.
5. Look for the data to change, the actuation to be interrupted, or for the DTC to reset during the wiggle test.
6. Perform any Technical Service Bulletins (TSBs) that may apply.
7. Turn the ignition off.
8. Visually inspect the related wire harness. Disconnect all the related harness connectors. Look for any chafed, pierced, pinched, partially broken wires and broken, bent, pushed out, or corroded terminals.
9. Perform a voltage drop test on the related circuits between the suspected component and the BPCM.
10. Inspect and clean all Battery Pack and chassis grounds that are related to the most current DTC.
11. If numerous trouble codes were set, use a schematic and inspect any common ground or supply circuits.
12. Use the scan tool to perform a System Test if one applies to the component.
13. A co-pilot, data recorder, and/or lab scope should be used to help diagnose intermittent conditions.
