First gear operation only with inhibited engagement as a function of vehicle
speed. Engine braking is applied with reduced throttle.
First and second gear operation with inhibited engagement of second gear, as
a function of vehicle speed. Engine braking is applied with reduced throttle.
First, second and third gear operation with an inhibited third gear engagement
at high vehicle speed. Refer to the vehicle owner’s manual.
Engine braking is applied with reduced throttle.
First, second, third and fourth gear operation. First to second (1-2), first to third
(1-3), second to third (2-3), second to fourth (2-4), third to fourth (3-4), fourth
to third (4-3), fourth to second (4-2), third to second (3-2), third to first (3-1)
and second to first (2-1), shifts are all available as a function of vehicle speed,
throttle position and the time rate of change of the throttle position (forced
downshift). Lockup clutch may be enabled in 3rd and 4th gears depending on
vehicle type. Refer to the owner’s manual.
Rear band applied only, with inhibited engagement as a function of vehicle
speed, engine speed and throttle position. The inhibitor switch allows the en-
gine to start.
Reverse gear operation, with inhibitor engagement as a function of vehicle
speed, engine speed and throttle position. The inhibitor switch enables reverse
lamp operation.
Rear band applied only, with inhibited engagement as a function of vehicle
speed, engine speed and throttle position. The transmission output shaft is
locked. The inhibitor switch allows the engine to start.
Table 2.1 - Gear Selections
DRIVING MODE SELECTOR
The driving mode selector consists of a mode selection switch and indicator light. The driving mode selector is
located on the centre console. See figure 2,1.
The schedules available to be selected vary with vehicle types. Typically the driver should have the option to select
between ‘NORMAL’ , ‘POWER’ or ‘WINTER’ modes.
When ‘NORMAL’ mode is selected upshifts will occur to maximise fuel economy and the indicator lights remain
extinguished. When ‘POWER’ mode is selected upshifts will occur to give maximum performance and the ‘POWER’
mode indicator light is switched on. When ‘WINTER’ mode is selected, starting at second gear is facilitated, the
‘WINTER’ mode indicator light is switched on and the ‘POWER’ mode indicator light is switched off.
Refer to the vehicle owner’s manual for specific modes for each vehicle type.

IMMOBILIZER SYSTEM 9W-7
System Integration
The med 98.2 immobilizer is an anti-theft protection device allowing the start of the engine only if a specific authorization
is obtained during the start up phase. The med 98.2 will allow (prohibit) the start of the engine by driving ON (OFF) an
internal solenoid valve.
The med 98.2 is a single unit integrating the following subsystem :
la valve that allows (valve open) or blocks (valve closed) the fuel flow through the engine fuel system
la microprocessor control system to control and activate the valve during the start up of the engine, in order to
allow the start up only when a specific permission is given
the med 98.2 task is, therefore, to prevent the non authorized start up of the engine.
The functional unit includes also a basic set of electronic components whose function is to reduce its dependence on
the microprocessor control system: a part from a short temporarily period, during the start up phase, the electronics
allows the control system to excite and open the valve, but it doesn’t allow to close it.
The valve can be shut off only after the KL 15 has been deactivated.
The structure allows to obtain the highest degree of safe-operation (functionality fail-start): a failure in the
microprocessor unit cannot cause the shut-off of the valve. The main consequence of this type of failure is to prevent
the next engine start up.
As a result of the above considerations, the med 98.2 immobilizer can realize its anti-theft functionality only in conjunction
with a control device: the ICU.
The ICU, when requested, sends a coded message to med 98.2 according to a settled communication protocol. The
med 98.2 will allow the start of the engine based upon this message.
In addition to the basic anti-theft functionality, the 98.2 immobilizer provides a number of diagnostic services when it
is connected to an external test instrument (SCAN-100). Those connections are depicted in the following integration
diagram (Fig. 1), where the dashed line indicates a temporary link for diagnostic purposes, and the shaded area the
med 98.2 system’s physical boundaries:
