Code I052: Keep Alive Memory Error
A code I052 indicates "keep alive" or "long term" memory in IPC has been reset. This code will set anytime battery is disconnected. When code is set, IPC memory resets itself to initial values, eliminating any driver-desired changes. If code I052 sets and battery was known not to be disconnected, check contacts at IPC connector terminals A1 and C12. Also check ground continuity of terminals A5 and C16. See Fig 1.
