5. Wiggle the wires while checking for shorts and open circuits.
6. Perform a voltage drop test on the related circuits between the suspected faulty component and the Memory Seat Module.
7. Inspect and clean all grounds that are related to the most current DTC.
8. If numerous trouble codes were set, use a wiring schematic and look for any common ground or supply circuits
9. Monitor with the scan tool and wiggle the related wire harness to try to interrupt the actuation.
10. Use the scan tool to perform a System Test if one applies to failing component.
11. A co-pilot, data recorder, and/or lab scope should be used to help diagnose intermittent conditions.
