DTC Descriptor
DTC B1019: System Configuration Error
Circuit/System Description
When calibrating the liftgate position, the power liftgate control module (PLGM) is placed in a functional state to learn the liftgate travel limits. DTC B1019 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 PLGM, the PLGM will exit calibration mode and DTC B1019 will go to history. If the PLGM does not exit learn mode, DTC B1019 will remain current and indicate a fault.
Conditions for Running the DTC
System voltage to the liftgate control module must be 9-16 volts.
Conditions for Setting the DTC
Whenever the liftgate control module is replaced or reprogrammed.
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 status code. |
| • | A history DTC will clear after 50 ignition cycles or with a scan tool using the clear DTCs function. |
Diagnostic Aids
A new or reprogrammed control module will be in a locked state and will require an ignition cycle before the calibration procedure can be performed.

Circuit/System Testing
Perform the Liftgate Calibration Procedure. The liftgate module should learn the travel limits, exit the calibration mode, and B1019 should go to history.
| ⇒ | If the liftgate module does not exit learn mode after the calibration attempt, replace the liftgate module. |
Repair Instructions
Perform the
Diagnostic Repair Verification
after completing the diagnostic procedure.
