Code B552, BCM Keep Alive Memory Error (Riviera)

Code B552 indicates that the Keep Alive (Long-Term) Memory in the BCM has been reset. This will be the case whenever power is removed from the BCM (such as disconnecting the battery cables, disconnecting BCM power connector, or losing crank signal to the BCM). This code should be cleared from memory after restoring the BCM power supply.

When all diagnosis and repairs are completed, clear codes and verify operation.
