Sunroof Motor/Actuator Initialization/Teach Process
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2011 GMC Yukon XL, 2011 GMC Yukon, 2011 Chevrolet Tahoe, 2011 Chevrolet Suburban, and 2011 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
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.
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.
- Ensure that all electrical harness connectors are connected.
- Turn the ignition to ON.
- Completely close the sunroof window with the manual close switch.
- Press the sunroof vent switch to the vent open position until the sunroof window stops in vent location. After the sunroof reaches the vent position, release the vent switch and press and hold the vent switch again for approximate 10 seconds. Notice the rear edge of the sunroof mechanism will move, after the movement ends the Initialization/Teach Process is complete.
- Verify the operation of the sunroof in all positions.
IMPORTANT:
The initialization/teach procedure is not complete if the battery and/or ignition power has been interrupted during the process.
The Initialization/Teach Process must be restarted if the procedure is not carried out completely.
