DTC 45 - Receiver Processing Currently In 20 Second Lockout

Malfunction/Condition

At least 50 consecutive digital RF messages were received from a Remote Control Door Lock Transmitter that is programmed to the BCM, but the messages did not pass the encryption security test. The BCM will cease processing any Remote Control Door Lock Transmitter digital RF messages (good or bad) for 20 seconds.

Operational Effects

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

Potential Causes

The Remote Control Door Lock Transmitter has been in resync or program mode out of range of the BCM. This malfunction could also be encountered 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. This malfunction could be induced prior to the BCM entering the Diagnostic Mode.
