Test/Troubleshooting Guidelines
Some PMG/PCT functions depend on the vehicle ignition status. Always test with the key ON unless otherwise
noted
To avoid “No Defect Found” billing on returns, always confirm a part failure on a test bench or other vehicle
before requesting an RMA
A good ground is critical to pin-out testing and PMG function. Always test the vehicle ground connections
against a known good ground reference point, such as the cigarette lighter shield, CB ground, or an in-dash
ground post. Watch for “floating” grounds, indicated by a medium-ohm reading, 25-50 ohms, which slowly
climbs during testing and when the cab is electrically active.
When rebooting the PMG, always wait until the red LED goes out before reapplying power: the PMG includes
a capacitor that maintains it for 30+ seconds after external power is lost
Always watch for damaged connectors and cables. If you note damage, replace the damaged part before
proceeding through the troubleshooting
