Instructions) provides an overview of each diagnostic category.
DTC Descriptor
DTC B1019 00
- System Configuration Error
Circuit/System Description
When calibrating the liftgate position, the liftgate control module is placed in a functional state to learn the liftgate travel limits. 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 control
module, the liftgate control module will exit calibration mode and DTC B1019 00 become a history code.
Conditions for Running the DTC
The system voltage is 9-18 V.
Conditions for Setting the DTC
Whenever the liftgate control module is replaced or in learn mode.
Action Taken When the DTC Sets
The power liftgate system will be disabled.
Conditions for Clearing the DTC
* The DTC will be current until the liftgate calibration procedure has been completed.
* When the calibration procedure has been completed the DTC will be a history DTC.
Diagnostic Aids
Setting B1019 00 is normal after flashing the liftgate control module. This DTC will be current after flashing and the DTC will go to history after
learning. This is a normal behavior by design and is not necessary to replace the liftgate control module.

Circuit/System Testing
Perform the Liftgate Calibration (See: Body and Frame/Doors, Hood and Trunk/Trunk / Liftgate/Testing and Inspection/Programming and
Relearning). The K39 liftgate control module should learn the travel limits, exit the calibration mode, and B1019 00 will become a history code.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
