Dual Pane Sunroof And Sunshade: Notes

The hard wired circuits between components related to the operation of the dual pane power sunroof and sunshade system may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

However, conventional diagnostic methods will not prove conclusive in the diagnosis of the electronic module integral to the power sunroof or power sunshade motor. If the power sunroof or power sunshade switches, motors and circuitry test okay, but the express or Excess Force Limitation (EFL) features are still ineffective following the initialization procedures, the motor and module unit must be replaced.
