I052

Wiring Diagram:

Code I052 indicates that the keep alive - or "long term" - memory in the IPC has been reset. It is a normal occurrence whenever power or ground is removed from the IPC, such as anytime the battery has been disconnected and reconnected. When the code is set, IPC memory is reset to initial values; the climate control will revert to 75 set temp, "Auto" mode and "Auto" fan speed. Code I052 will disable all other codes.

If code I052 sets without a battery disconnect, ensure good terminal contacts at power feed pins "A1" and "C12", and grounds at pins "A5" and "C16".
