GFA Control Unit
The GFA control unit (Auxiliary Functions Management) is an on board computer that manages the operation of
many devices. The GFA is connected by CAN line to the LIE engine control unit and to the PCM control unit, and co-ordinates and manages many operations, especially concerning diagnostics.
The main functions controlled or coordinated by the GFA control unit are: •Cutting out accessory devices when the engine oil pressure is below 1 bar (pressure switch contact closed);
• Key inserted check and buzzer activation if the key is inserted and the driver’s door open after at least one KEY
ON;
• Check of light intensity on the instrument panel;
• Lights on check, activating the buzzer if lights are on, key inserted and driver’s door open;
• Check on driver’s side seat belt with timed activation of buzzer and key inserted warning light;
• Passenger compartment light check;
• Exhaust gas temperature in catalytic converter check (see GR.15 .– Engine Control);
• Instruments (fuel level indicator) and other indicators check;
• Front differential temperature check;
• Lifting system check;
• OBDII management (Engine Error);
• OBDII management (Gearbox Error 8 6 $ Y H U V L R Q
).
