DIAGNOSIS AND TESTING - POWER TAILGATE SYSTEM
The power tailgate system is a complex system containing many components. In order to perform conclusive testing,
or receive outputs the power tailgate control module must be checked.
The most reliable, efficient, and accurate means to diagnose the power tailgate system requires the use of a scan tool
and the proper Body Diagnostic Procedures manual. The scan tool can be used to observe current switch status
recorded in the power tailgate control module to help the technician diagnose an inoperative switch.
Before any testing of the power tailgate system is attempted, the battery should be fully charged, all power tailgate
system inhibitors read and understood (Refer to power tailgate system description for list).
Following are quick reference diagnostic tables to help when diagnosing and testing the power tailgate system.
