DTC B1552: Description

DTC B1552 indicates that battery-backed or Keep Alive Memory (KAM) has been reset. This occurs when power or ground is removed from IPC, such as disconnecting vehicle battery. When DTC B1552 is set, IPC KAM data is reset to initial values (Trip Odometer, Average Fuel Economy, Fuel Used and Average MPG). If battery is disconnected, climate control will display 75° set temperature, "Auto" mode and "Auto" fan speed. If problem is solely with IPC, climate control should return to previous settings.
