STANDARD PROCEDURE
POWER SUNROOF TIMING
NOTE: Perform the timing procedures if any of the following conditions exist:
- Glass skewed in the channel
- One side of the glass dropping before the other while moving from “VENT” to “CLOSE”
- Glass reversing direction when closing the sunroof
- Glass will not close or may stop at the wrong location
- The glass may over travel the “OPEN” position and stall the motor
- The glass may over travel the “CLOSE” position and stall the motor
NOTE: The timing of the motor/module and the sunroof assembly play a critical role in the proper function of the sunroof. If the motor/module is removed and the sunroof glass or cables are moved the sunroof module will have to be timed. REFER to the following procedure for the necessary steps.
1. Perform the motor/module re-initialization procedure, (Refer to 8 - ELECTRICAL/POWER TOP/MOTOR - STANDARD PROCEDURE).
2. Remove the motor/module, (Refer to 8 - ELECTRICAL/POWER TOP/MOTOR - REMOVAL).
3. Remove sunroof glass panel (Refer to 23 - BODY/SUNROOF/GLASS PANEL - REMOVAL) .
4. Now place both right and left arms in the closed position. Using a screwdriver, push the plastic cable all the way forward in the track until the glass mounting arm drops into the closed position.
5. Repeat this on the other side.
6. To verify correct timing, there is an 1/8 inch hole in the cable ramp that must be aligned with the front glass mounting screw hole.
7. Using an awl, verify alignment of both right and left timing holes. The tracks will now be timed to the fully closed position.
8. Install the motor/module (Refer to 8 - ELECTRICAL/POWER TOP/MOTOR - INSTALLATION).
9. Install the sunroof glass panel, (Refer to 23 - BODY/SUNROOF/GLASS PANEL - INSTALLATION).
10. Perform the motor/module re-initialization procedure, (Refer to 8 - ELECTRICAL/POWER TOP/MOTOR - STANDARD PROCEDURE).
RE-INITIALIZATION
NOTE: If for some reason the sunroof is not operating normally it may be necessary to re-initialize the sunroof assembly. This procedure should be attempted prior to any diagnosis of the sunroof system.
NOTE: The re-initialization procedure is not complete if any one of the following conditions occurs before the re-initialization procedure is completed:
- The sunroof switch is not held in the CLOSE position.
- The ignition or battery power is lost.
- The glass panel has not reached its closed position.
NOTE: If the re-initialization procedure is not carried out completely, it must be started over.
1. Cycle the sunroof to full “OPEN” position.
2. Once the sunroof is in the full “OPEN” position, press and continuously hold the “OPEN” button on the sunroof switch.
3. After a delay of 10 seconds the sunroof will begin to move past the normal “OPEN” position to the hard stop position. It will then reverse to the normal “OPEN” position also known as the soft stop. Once the sunroof has reversed to the soft stop, immediately (within 5 seconds of stopping travel) release the “OPEN” button and continuously press it again.
4. After a delay of three seconds the sunroof will begin moving to the “VENT” and then “CLOSED” position. When the roof reaches the fully “CLOSED” position and stops the “OPEN” button can be released.
The re-initialization procedure is now complete. Operate the sunroof in all directions to verify proper operation.
INITIALIZATION
NOTE: This procedure should be attempted any time a new motor/module is installed in the sunroof assembly. It must be performed on initial vehicle power up to be successful.
NOTE: The initialization procedure is not complete if any one of the following conditions occurs before the initialization procedure is completed:
- The sunroof switch is not held in the CLOSE position.
- The ignition or battery power is lost.
- The glass panel has not reached its closed position.
NOTE: if the initialization procedure is not carried out completely, it must be started over.
1. Turn the ignition key to the “RUN” position.
2. Move the sunroof to the full open position.
3. Continuously press the “OPEN” button on the sunroof switch.
4. The sunroof will begin to move past the normal “OPEN” position to the hard stop position. It will then reverse to the normal “OPEN” position also known as the soft stop. Once the sunroof has reversed to the soft stop, immediately (within 5 seconds of stopping travel) release the “OPEN” button and continuously press it again.
5. After a delay of three seconds the sunroof will begin moving to the “VENT” and then “CLOSED” position. When the roof reaches the fully “CLOSED” position and stops the “OPEN” button can be released.
The initialization procedure is now complete. Operate the sunroof in all directions to verify proper operation.
