Power Sunroof

DIAGNOSIS AND TESTING - SUNROOF SYSTEM

The hard wired circuits between components related to the operation of the single pane power sunroof 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 motor. If the power sunroof switches, motors and circuitry test okay, but the express or Excess Force Limitation (EFL) features are still ineffective following the calibration and initialization procedures, the motor and module unit must be replaced.

NOTE: If there is no sliding sunroof panel movement when the power sunroof switch OPEN or CLOSE push button is depressed, but there is movement when the VENT push button is depressed, the sunroof module requires calibration. Complete the Single Pane Sunroof Motor And Module Initialization procedure prior to performing any further sunroof diagnosis. Programming and Relearning .
