Power Sliding Door (PSD) Diagnostic System Check (Part 3 Of 3):

INTRODUCTION
The Power Sliding Door (PSD) diagnostic system check is an organized approach to identify problems associated with the PSD. The PSD diagnostic system check must be the starting point for any PSD-related complaint, and will direct you to the next logical step in diagnosing the complaint.

The PSD is very reliable component and is not likely the cause of the malfunction. Most PSD complaints are linked to the mechanical operation of the sliding door, faulty wiring, connectors, and other components. Understanding how the PSD operates and using the diagnostic tables correctly will reduce diagnostic time and prevent unnecessary parts replacement.

DIAGNOSTIC AIDS
- The following conditions may result in an intermittent operation of the PSD with no DTC stored:
- Any condition that results in the interruption of power to the system.
- An out of range battery voltage specification. Normal battery voltage: 10-16V.
- Loose or damaged ground(s).
- An intermittent failure may be very difficult to detect and to accurately diagnose. Faulty electrical connections or wiring causes most intermittent problems. When an intermittent condition is suspected, check the suspected circuits for the following conditions:
- Poor mating of connector halves or backed out terminals.
- Improperly formed or damaged terminals. Wire chafing.
- Poor wire to terminal connections.
- Dirty or corroded terminals.
- Damage to connector bodies.
- Wire broken inside the insulation.
