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

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 liftgate module, the liftgate module will exit calibration mode and DTC B1019 00 become a history code.
