Reset/Initialization



Outline

  1. Electric sunroof system consists of

    Sunroof switch
     
    Sunroof motor assembly
     
    BCM (body control module)
     

  2.  
  3. BCM supplies power to the sunroof motor. Sunroof operation depends on sunroof switch condition.
  4.  

Operation

  1. Power is supplied at all times

    through 50A fusible link (letter j, located in the fuse and fusible link box)
     
    to BCM terminal 70, and
     
    through BCM terminal 69
     
    to sunroof motor assembly terminal 7.
     

  2.  
  3. When the ignition switch is in the ON or START position, power is supplied

    through 10A fuse [No. 12, located in the fuse block (J/B)]
     
    to BCM terminal 38, and
     
    through BCM terminal 68
     
    to sunroof motor assembly terminal 9.
     

  4.  
  5. Ground is supplied

    to BCM terminal 67
     
    through grounds M57 and M61.
     

  6.  

Tilt Up/Slide Close Operation

  1. When up/close switch is pressed, ground is supplied

    to sunroof motor assembly terminal 1
     
    through sunroof switch terminal 3
     
    through sunroof motor assembly terminal 10
     
    through sunroof switch terminal 2
     
    through grounds M57 and M61.
     

  2.  
  3. Then the sunroof will tilt up/slide closed.
  4.  

Tilt Down/Slide Open Operation

  1. When down/open switch is pressed, ground is supplied

    to sunroof motor assembly terminal 5
     
    through sunroof switch terminal 1
     
    through sunroof motor assembly terminal 10
     
    through sunroof switch terminal 2
     
    through grounds M57 and M61.
     

  2.  
  3. Then the sunroof will tilt down/slide open.
  4.  

Auto Operation

  1. The power sunroof AUTO feature makes it possible to slide open and slide closed or tilt up and tilt down the sunroof without holding the sunroof switch in the UP/CLOSE or DOWN/OPEN position.
  2.  

Retained Power Operation

  1. When the ignition switch is turned to OFF position from ON position, power is supplied for 45 seconds

    through BCM terminal 68
     
    to sunroof motor assembly terminal 9.
     

  2.  
  3. When power is supplied, the sunroof can be operated.
  4.  
  5. The retained power operation is canceled when the front door LH or RH is opened.
  6.  
  7. RAP signal period can be changed by CONSULT-III. See Diagnostics Section.
  8.  

Anti-Pinch Function

  1. The CPU (central processing unit) of sunroof motor assembly monitors the sunroof motor operation and the sunroof position (fully-closed or other) by the signals from sunroof motor.
  2.  
  3. When sunroof motor detects an interruption during the following slide close and tilt down operation, sunroof switch controls the motor for open and the sunroof will operate until it reaches full up position (during tilt down operation) or 125 mm (4.92 in) or more in an open direction (during slide close operation).

    close operation and tilt down when ignition switch is in the ON position.
     
    close operation and tilt down during retained power operation.
     

  4.  

Initialization Failure Conditions

  1. Initialization and teaching of system should be conducted if the following conditions exist:

    sunroof will only move in the UP/CLOSE direction, having a step by step motion
     
    sunroof does not have any auto operation.
     

  2.  

Initialization Procedure

If the sunroof does not close or open automatically, use the following procedure to return sunroof operation to normal.

  1. Press the switch to the UP/CLOSE position to tilt the sunroof up fully. When the sunroof reaches the full tilt up position it will back up a few millimeters and stop.
  2.  
  3. Release the UP/CLOSE switch.
  4.  
  5. Within 5 seconds of releasing the UP/CLOSE switch, press and hold the UP/CLOSE switch again. The sunroof will move to the full open position and back to the closed position.
    NOTE
    If the UP/CLOSE switch is released anytime during this teaching process, all learned profile data will be discarded and the procedure will have to be started over.

  6.  
  7. 4. Release the UP/CLOSE switch. Do not disconnect power for at least two seconds. The sunroof is now initialized and taught.
  8.  

Initializing procedure is complete. Confirm proper operation of the sunroof (slide open, slide closed, tilt up, tilt down).

Re-Teaching Conditions

  1. Re-teaching of system should be conducted if any of the following conditions exist:

    the sunroof is manually operated using the sunroof wrench with the battery discharged or disconnected.
     
    the sunroof is manually operated using the sunroof wrench with the key switch in the OFF position and retained power timed out (after approximately 45 seconds or with a front door open).
     
    the sunroof motor assembly is replaced with a new one.
     
    the sunroof motor is removed from the sunroof assembly and operated before it is reinstalled.
     
    the sunroof motor is removed from the sunroof assembly and the glass panel position is changed.
     

  2.  

Re-Teaching Procedure

  1. Using the UP/CLOSE switch, move the sunroof toward the tilt position until it stops.
  2.  
  3. Release the UP/CLOSE switch.
  4.  
  5. Press the UP/CLOSE switch again and continuously hold. The sunroof will begin to move in about 10 seconds.
  6.  
  7. Continue to hold the UP/CLOSE switch while the sunroof moves in a jogging motion to the full tilt position. When the sunroof reaches the full tilt position, it will back up a few millimeters and stop.
  8.  
  9. Release the UP/CLOSE switch.
  10.  
  11. Within 5 seconds of releasing the UP/CLOSE switch, press and hold the UP/CLOSE switch again. The sunroof will move to the full open position and back to the closed position.
    NOTE
    If the UP/CLOSE switch is released anytime during this teaching process, all learned profile data will be discarded and the procedure will have to be started over.

  12.  
  13. Release the UP/CLOSE switch. Do not disconnect power for at least two seconds. The sunroof is now retaught.
