Diagnostic Test
INTERMITTENT DTC
- The conditions necessary to set this DTC are not present at this time.
- Review the scan tool environmental data. If possible, try to duplicate the conditions under which the DTC set.
- If applicable, actuate the component with the scan tool.
- Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors.
- Look for the data to change, the actuation to be interrupted, or for the DTC to reset during the wiggle test.
- Perform any Technical Service Bulletins (TSBs) that may apply.
- Turn the ignition off.
- 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.
- Perform a voltage drop test on the related circuits between the suspected component and the BPCM.
- Inspect and clean all BPCM and chassis grounds that are related to the most current DTC.
- If numerous trouble codes were set, use a schematic and inspect any common ground or supply circuits.
- Use the scan tool to perform a System Test if one applies to the component.
- A co-pilot, data recorder, and/or lab scope should be used to help diagnose intermittent conditions.
Were any problems found during the above inspections?
Yes
- Perform the necessary repairs.
- Perform the BATTERY PACK CONTROL MODULE (BPCM) VERIFICATION TEST. Refer to STANDARD PROCEDURE .
No
- Test Complete.
