Diagnosis And Testing - Power Trunk Lid System
The power trunk lid system is a complex system containing
many components. In order to perform conclusive testing, or receive
outputs the power trunk lid control module must be checked.
The most reliable, efficient, and accurate means to diagnose
the power trunk lid 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 trunk lid control
module to help the technician diagnose an inoperative switch.
Before any testing of the power trunk lid system is
attempted, the battery should be fully charged, all power trunk lid
system inhibitors read and understood (Refer to power trunk lid system
description for list).
Following are quick reference diagnostic tables to help when diagnosing and testing the power trunk lid system.
