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
).

1. Connect the LDAS32 diagnostic interface to the car.
2. While the engine is switched off check the following values:
PA: accelerator pedal in the idle position. Must equal 150 +- 15 bit. An incorrect adjustment generates error codes.
PA: accelerator pedal in the maximum position. Must equal 700 +- 15 bit. An incorrect adjustment generates error codes.
If the idle speed is not set correctly, act on the accelerator pedal lever.
4. If the maximum is not set correctly, act on the accelerator pedal stroke.
Check all the engine parameters using the LDAS32 display. In the indicated conditions all the LEDs will be
green: in particular environment temperature conditions (<10°C or >35°C) some LEDs may be red; this is
normal if the values of the relative parameters are congruent with such temperatures.

Adjustment of idle status is automatic and managed completely by the LIE;
when the engine has reached idle speed
(tH2o >85° and T oil >90°) throttle self learning can take place (the Idle Self Learning Timer decreases from 3 to 0 and the sl time counter increases from 0 to 60 seconds, setting the correct air percentage).
