DTC Descriptor



DTC B1019 00



- System Configuration Error



Circuit/System Description



When calibrating the liftgate position, the liftgate module (LGM) 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 LGM, the



liftgate 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 LGM 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 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 module.
