Power Sunroof



Diagnosis & Testing

Any diagnosis of the power sunroof system should begin with the use of a scan tool and the proper Diagnostic Procedures Information. The scan tool can provide confirmation that the Controller Area Network (CAN) Data Bus circuit is functional, that all of the electronic modules are sending and receiving the proper messages on the CAN Data Bus, and that the power sunroof motor/module assembly is being sent the proper hard wired output by the sunroof switch.

Refer to the list below for possible causes. Before beginning sunroof diagnostics, verify that all other power accessories are in proper operating condition. If not, a common electrical problem may exist. Refer to Wiring Diagrams in this publication for circuit, splice, and component descriptions.

Check the condition of the circuit protection (20 amp circuit breaker in the Junction Block). Inspect all wiring connector pins for proper engagement and continuity. Check for battery voltage at the power sunroof controller, refer to Wiring Diagrams, for circuit information.

If a battery voltage of more than 10 volts is detected at the controller, proceed with the following tests (the controller will not operate at less than 10 volts).

  1. The sunroof motor is inoperative. Possible causes:

    Faulty control switch
     
    Faulty circuit ground between the sunroof module, control switch, and body harness
     
    Faulty power circuit between the sunroof module, control switch, and body harness
     
    Faulty sunroof drive motor
     
    Faulty sunroof module
     

  2.  
  3. Audible whine when the switch is depressed, the sunroof does not operate. Possible causes:

    Binding cable
     
    Faulty sunroof drive motor
     

  4.  
  5. Audible clicking or ratcheting when the switch is pressed, the sunroof does not operate. Possible causes:

    Broken or worn drive cable
     
    Worn drive motor gear
     
    Mechanisms not synchronized
     

  6.  
  7. Sunroof vents and opens, but does not close. Possible causes:

    Broken or disengaged trough guide
     
    Binding cable
     
    Faulty circuit
     
    Faulty control switch
     
    Faulty sunroof module
     
    Faulty drive motor
     

  8.  
  9. Sunroof vents, but does not open. Possible causes:

    Faulty control switch
     
    Faulty circuit
     
    Binding cable or mechanism
     
    Faulty sunroof module
     

  10.  
  11. Sunroof does not vent. Possible causes:

    Faulty control switch
     
    Faulty circuit
     
    Binding cable or mechanism
     
    Faulty sunroof module
