DTC Descriptor
DTC B1019 00: System Configuration ErrorCircuit/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 liftgate module, the LGM will exit calibration mode. If the LGM does not exit learn mode, DTC B1019 00 will remain current and indicate a fault.
Conditions for Running the DTC
The system voltage is 9-16 volts.
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. |
| • | A history DTC will clear after 50 ignition cycles. |
Diagnostic Aids
A new or reprogrammed LGM will be in a locked state and will require an ignition cycle before the calibration procedure can be performed.

Circuit/System Verification
Perform the Liftgate Calibration. The LGM should learn the travel limits, exit the calibration mode, and B1019 00 should clear.
| ⇒ | If the LGM does not exit the learn mode after the calibration attempt, replace the LGM. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
