DTC 44

DTC 44 Last Transmitter Message Received had Encryption Error (With AU0 only)

Malfunction/Condition:
The digital RF message received was from a Remote Control Door Lock Transmitter that is programmed to the BCM, but the message did not pass the encryption security test.

Operational Effects:
No remote function capability (i.e. Lock, Unlock, etc.)

Potential Causes:
The Remote Control Door Lock Transmitter has been in the program or resync mode out of range of the BCM. This Malfunction could also be encountered if the digital RF message has an error due to noise from the surrounding environment or if the Remote Control Door Lock Transmitter itself is defective.

Comments:
The most likely cause is the Remote Control Door Lock Transmitter out of sync with the BCM. To resync the transmitter to the BCM, press "Lock" and "Unlock" buttons on the Transmitter at the same time for 5 seconds.
