Partially open and closes but is crooked and won't seal all the way
Circuit/System Description
By performing the initialization/teach procedure, the sunroof motor/actuator records the open vent stop position. The motor/actuator will then understand the other positions, closed and full open soft stop, and allow express and obstacle detection functions.
Important: Apply ground to the module for no longer than 2 seconds at a time or the module could be damaged.
The sunroof control module supplies each of the sunroof switch signal circuits with a 12-volt reference. When a switch is pressed the signal circuit is pulled low signaling the sunroof open or close request. The module determines the motor direction based on inputs received from the sunroof switch.
Sunroof Motor/Actuator Initialization/Teach Process
Perform the initialization/teach procedure any time:
?€¢
A new sunroof motor/actuator has been installed.
?€¢
The existing sunroof motor/actuator has been removed and reinstalled.
?€¢
The sunroof system has suffered 3 interruptions for emergency events, i.e. anti-pinch, debris in tracks etc., and normal operation is canceled.
If this does nothing !
The Initialization/Teach Process must be restarted if the procedure is not carried out completely.
Important: Because of the accessibility of the sunroof switch, perform the sunroof switch component test before beginning the Circuit/System Testing.
Power Sunroof Malfunction
If greater than the specified range, test the ground circuit for an open/high resistance.
If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal and the B+ circuit fuse is open, replace the fuse and replace the sunroof control module.
If the test lamp does not illuminate, test the ignition circuit for an open/high resistance. If the circuit tests normal, refer to Retained Accessory Power (RAP) Malfunction.
If the test lamp does not illuminate, test the ignition circuit for an open/high resistance. If the circuit tests normal, refer to Retained Accessory Power (RAP) Malfunction.
If greater than the specified range, test the ground circuit for an open/high resistance.
When performing the following tests, make sure that the sunroof or sunshade is not at its end of travel position by switching the grounded jumper to the other signal circuit if the sunroof or sunshade does not move in one direction.
If the sunroof does not move, test the signal circuit for a short to ground, short to voltage or an open/high resistance. If the circuit test is normal, replace the sunroof control module.
If the sunroof does not move, test the signal circuit for a short to ground, short to voltage or an open/high resistance. If the circuit test is normal, replace the sunroof control module.
If the sunroof does not vent open, test the signal circuit for a short to ground, short to voltage or an open/high resistance. If the circuit test is normal, replace the sunroof control module.
If the sunroof does not close, test the signal circuit for a short to ground, short to voltage or an open/high resistance. If the circuit test is normal, replace the sunroof control module.
