FMI 223 CAT Fault Code

Cause :

Malfunction in the thermostat control system. The on-board computer reports problems with communication with the control unit, so a possible cause may be poor contact. The cooling system circuit is open, which may affect the operation of the power unit as a whole.This combination is associated with interruptions in the ignition cylinders of the power unit. The cylinder number is not indicated, therefore, the user must independently check each element, including compression.
