Firebird V8-350 5.7L VIN P SFI (1996)
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.
