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 9-16 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.
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.
