( Q J L Q H When working on vehicles equipped with LIE engine control system, the following rules must be observed: •Never start up the engine when the electrical connection terminals are badly connected or loosened on the battery terminals;
• Do not use a fast battery charger to start the engine;
• Never disconnect the battery from the electrical system when the engine is running;

• If the vehicle goes into a drying oven at a temperature over 80°C after varnishing, the system control units must be disassembled and removed from the vehicle;
• Do not connect/disconnect the control unit multiple connector with the ignition switch in “ON” position;
• Disconnect the LIE, PMC, GFA and ETB control unit connectors before carrying out any electrical welding on the vehicle;
• Always disconnect the LIE small connector before disconnecting the big one. When connecting again, connect the big connector before connecting the small one;
• Disconnect all the electronic control units and in particular the LIE, GFA and ETB control units.

Lifting System
This is an hydraulic device enabling to lift the front part of the vehicle when driving at low speed, to allow access to areas with uneven surfaces. The system is composed of the following components:•Front shock absorbers;
• Electronic control unit (GFA);
• Ascent or descent control button;
• Connecting hoses and electric wires;

E. 3 R Z H U V W H H U L Q J À X L G U H V H U Y R L U
F. Hydraulic pump
The system can be activated up to the maximum speed of 70 Km/h (30 Km/h for Japan); when it reaches this speed threshold the system will automatically go to the DOWN position. Moreover the system can recognize the following lifting system errors: • System pressure indicated simultaneously by two pressure switches as under 20 bars and over 70 bars (one or
both pressure switches damaged or disconnected).
• Vehicle ascending or descending time greater than 120 seconds (hydraulic or solenoid valve problem).
• Wrong vehicle speed indication.
The warning light on the dashboard will blink quickly to signal errors (it blinks slowing during raising/lowering).If problems occur the L.DAS software is used, which checks system errors and proceeds by resetting them.

To assemble the pedal on the pedal cluster:
1. Position the pedal ( A-Fig.1) using the shims ( B-Fig.1) (1 shim for E-Gear cars, 2 for manual gearbox cars).
2. Insert the shaft from the right and use the LH snap ring to adjust the stroke.
3. Position the snap ring ( C-Fig.1) on the right.
4. Insert the journal ( D-Fig.2) and secure using the clip ( E-Fig.2) to anchor the pin ( F-Fig.2) to the fork ( G-
Fig.2 ).
5. Connect the pedal to the support using the spring ( H-Fig.1) (1 spring for E-Gear cars, 2 for manual gearbox
cars).

The PCM control unit receives, through the CAN line, from LIE and GFA control units, information concerning the following parameters: •Engine coolant temperature ;
• Ambient temperature;
• Vehicle speed.
The air vent condition according to these parameters is the following:

The values stated may vary
With vehicle speed above 180 km/h, the air vents keep the same condition as the moment in which the speed limit is exceeded (if they were open they stay open and vice versa).If the air vents are moving (opening or closing) when the speed limit is exceeded, they are forced to open.
The adjustment push-button is active up to 50 km/h: The system logic operates according to engine conditions: If
the air vents are open because of too high engine or outside air temperature, they cannot be closed by means of the push-button.Hysteresis on coolant temperature: 5 °C when closing.Hysteresis on outside air temperature: 3 °C when closing. The opening is disabled for 30 sec. after the start.
