Circuit/System Description

When calibrating the liftgate position, the rear gate module is placed in a functional state to learn the liftgate travel limits. DTC B1C0A 54 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 rear gate module, the rear gate module will exit calibration mode and DTC B1C0A 54 become a history code.
