B556

Keep Alive Memory Circuit:

CIRCUIT DESCRIPTION:
Code B556 indicates that the BCM EEPROM, which records elapsed odometer mileage, is not being read by the BCM. Usually, "ERROR" will be displayed in place of the mileage on the IPC while Code B556 is set (Digital cluster only).

^ If a properly installed EEPROM continues to set Code B556, replace the BCM.
