Liftgate Calibration

2014 Buick Enclave ConvenienceSECTION Liftgate Calibration

NOTE: To ensure proper calibration of the liftgate, the liftgate assembly must be at room temperature during calibration.

Power liftgate calibration must be performed after any of the liftgate system components have been disconnected, disassembled, repaired or replaced.

Conditions

Use this procedure after replacing, repairing or disassembling any portion of the power liftgate assembly.

NOTE: The liftgate must be in the full closed position when performing the liftgate calibration procedure. Failure to do so will result in a failed liftgate calibration.

Calibrate Liftgate

Close the liftgate.
Install a scan tool.
Clear All DTCs before proceeding.
Navigate to the Liftgate Module menu.
Select Module Setup menu item
Select LGM Open/Close Test and follow the directions displayed on the screen

NOTE: DTC B1019 00 will set automatically as an indicator that the system is in learn mode and not as a fault indicator. Once the travel limits are learned by the LGM, the liftgate module will exit calibration mode and DTC B1019 00 become a history code. You will hear a loud clunk at the top of travel the first time the liftgate opens. The system is learning where full open is for this vehicle. There will be no clunk after the first full opening and closing.
