B552

Keep Alive Memory Circuit:

CIRCUIT DESCRIPTION:
Code B552 indicates that the keep alive - or "long term" - memory in the BCM has been reset. It is a normal occurrence whenever power is removed from the BCM, such as anytime the battery has been disconnected and reconnected. Code B552 may only be cleared if it is not current. Under normal conditions, the code will become history by the following:

^ Key in "LOCK."
^ Wait 5 seconds.
^ Key "ON" - Re-enter Diagnostics.

This code should now be history, and can be cleared in the normal manner.
