It is a sensor generating an electric signal according to the ratio between the oxygen inside the exhaust gas and the
oxygen inside the outside air. By means of this sensor it is possible to measure the deviation from the stoichometric ratio (lambda ratio) of the air – fuel mixture sent to the cylinders.
Each cylinder bank has two oxygen sensors: one is installed on the exhaust gas inlet coupling in the catalytic converter of the exhaust system, the other on the converter outlet.

B. Post-catalyst oxygen sensor (ON-OFF)

$ , 5 % $ * control unit
The electronic control unit governs and activates the various airbag modules. The ECU contains following parts: • an aluminum container in which the following are arranged:
• an electromechanical sensor which discriminates the “activation/deactivation” conditions according to vehicle
deceleration;
• an electromagnetic safety sensor operating with the electromechanical sensor; both sensors must enable the
“activation” condition for the system to be deployed;
• an electronic board that analyses the signals from the two sensors and deploys the airbag modules when
required.
Furthermore, the electronic board has self-diagnostic features. When the ignition key is turned to “MAR”, it checks
the correct operation of the entire system. During the test a red warning light on the dashboard turns on. The
warning light turns off approximately four seconds after the engine is started if the system is working correctly. The airbag system will need to be attended to at an authorized workshop if either the red airbag warning light on the dashboard stays on for longer than 4-6 seconds after the engine has been started or turns on while traveling.

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.
