DTC B1019

Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle (Initial Inspection and Diagnostic Overview) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (Initial Inspection and Diagnostic Overview) for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions (Initial Inspection and Diagnostic Overview) 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 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 9-18 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 (Programming and Relearning). The LGM should learn the travel limits, exit the calibration mode, and B1019 00 should clear.

If the LGM does not exit learn mode after the calibration attempt, replace the LGM.

Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
