Switch Matrix cable harness for diagnostics

For use of the cable harness, it is essential that the key is turned to OFF when the SD3 is activated, until the ECU to be diagnosed has been selected. Thisis because in certain conditions, some errors may occur on the CAN lines, which would cause the warning lights on the instrument panel to flash.

Locking/unlocking the vehicle using the remote control:

Door lock button:

Button pressed once: If the alarm system fails, the siren will emit a long beep and the red LEDswill start flashing quickly. If one of the doors has not been closed properly, the doors do NOT lock and the alarm system is NOT activated. The directionindicators and the red LEDsflash nine times (three seconds).

Button pressed at length: the windows close.

Releasing the button: the windows stop closing .

Door unlock button:

Button pressed twice: All the doors are unlocked (if enabled by the NIT, only the driver’s door is unlocked), Low beams activated for 30 seconds

Button pressed at length: the windows open.

Releasing the button: the windows stop opening.

Locking/unlocking the vehicle using the internal buttons: Luggage compartment opening button: button pressed at length: the luggage compartment is opened (when the vehicle speed is below 4 Km/h or when the vehicle is off)

Locking/unlocking the vehicle using the button on the external revolving pawls:

Key turned anticlockwise in DRIVER’S door lock (Opening): all doors are unlocked (or driver’s door only if set through the NIT) If the alarm is enabled: the red LEDswill turn off for 4 seconds (when this time has elapsed, they will start flashing again). When a door is opened the acoustic alarm is activated.

Key turned clockwise in PASSENGER'S door lock (opening): all doors are unlocked. If the alarm is enabled: the red LEDswill turn off for 4 seconds (when this time has elapsed, they will start flashing again)

NOTE: When the vehicle is unlocked from the outside with the key, the alarm system is not deactivated. To deactivate the alarm system, simply insert the key in the ignition block. The immobilizer acknowledges the code automatically.

Locking/unlocking the doors and the luggage compartment

Inertia switch: the activation of the inertial switch unlocks all the doors andthe luggage compartment and turns on the internal dome light and the four direction indicators. This is located underneath the driver’s seat.

Vehicle speed over 20 Km/h : when the vehicle speed exceeds 20 Km/h the doors are locked if this function has been previously set through the IT Info Node (NIT) user menu

Dead battery: vehicle closing. The two front doors must be locked.

Vehicle setup: From the NIT user menu, you may decide whether to unlock both the doors or just the door on the driver’s side.

From the relative menu, you can choose whether the luggage compartment should be connected to the door locking or whether it should be operated independently.

Alarm System

The alarm system of the Maserati GranTurismois identical to the system used in the Quattroporte.

Activation:the direction indicators will turn on permanently, and the alarm siren will emit a synchronised beep. A red LED will now start flashing intermittently to indicate a "surveillance" status.

Deactivation: the direction indicators will flash twice, the alarm siren will emit a double beep. NOTE: The alarm system is also deactivated by inserting a key with an ID code in the ignition key barrel, so that the immobilizer can recognise it.

Motion-sensing and anti-inclination alarm: when the alarm system is deactivated, the motion-sensing and anti-inclination alarm can be turned off using the buttons provided on the front dome lamp.

Luggage compartment opening: the luggage compartment can be opened using the remote control; in this case, the motion and inclination sensorsare temporarily deactivated. If the luggage compartment is then closed, the sensors will be reactivated.

ECU self learning:

Every time the battery is removed, a self-learning cycle is required so that certain ECUs can operate correctly.

•Motor-driven throttle: turn the ignition switch to the ON position (Key ON) and wait for at least 30 seconds.

•Locking/unlocking the doors and luggage compartment: lock and then unlock the doors using the remote control or the key.

•NIT (IT Info Node): reset the correct time using the specific NIT service menu

External lights

(1) The side markers, provided as a standard equipment for all the markets, improve driving safety and are also an attractive aesthetic element

(2) Front direction indicator repeater

(3) Position light

(4) Bi-xenon headlight –low-beam + highbeam

(5) Additional low-beam (Flash to Pass ) –the bi-xenon lamps take some time to reach maximum efficiency, therefore, while the bixenon headlights are off, the flashing function is assured by a conventional light.

(6) Front headlight cleaning system

(7) Fog light

Adaptive light adjustment

The Maserati GranTurismois fitted with a set of self-levelling bi-xenon headlights with fully automatic adjustment system. The high performance of the bi-xenon headlights is enhanced even further by the rotation function which, by improving the illumination of the road and surrounding areas, contributes to increasing driving safety during night-time on particularly twisty roads. The high-beam and low-beam control unit instantaneously receives and processes the information on steering, camber and driving speed and acts on special electric motors that turn the light cones in order toincrease side illumination.

Operating strategy:

•The system is activated at a speed of 5 km/h.

•The maximum headlight rotation inside a curve is 15°and for the headlight outside a curve 7.5° (always half);

•From 90 km/h to 120 km/h the rotation is less

•Over 120 km/h and in reverse, the system is deactivated for safety reasons.

IntroductiontoMaserati

When replacing the left-hand headlight, perform the two calibration cycles on both NFA ECU.

•Connect the diagnostic tester to the EOBD socket on the Body Computer Node and calibrate the Self-adaptive Headlight Node (NFA). This cycle involves the calibration of the left-hand headlight (MASTER) and subsequently of the right-hand one (SLAVE).

•The two cycles are independent, therefore you will have to launch first the MASTER calibration cycle and then the SLAVE one.

•In the event of a collision involving the left-hand headlight, the signal connector for the CAN line may be damaged. The damaged connector may interfere with proper vehicle starting. Therefore, if the vehicle cannot be used after a collision and the headlight is damaged, detach the CAN line connector and check engine starting.

If replacing the battery, the PROXY alignment procedure does nothave to be performed; when the key is next turned to on and with the headlights on, the node performs a selflearning process as calibration.

Lights managed by the twilight sensor (AUTO mode): the external lights are activated automatically by the twilight sensor. From the NIT user menu, you can set the twilight sensor’s sensing range (3 levels).

Follow me home

This control enables the position lights and low beams to switch on automatically for a timed period, immediately after the vehicle is turned off (Key-OFF).

Activation: After turning the key to OFF, you must operate the control forflashing the headlights, found on the steering column stalk. The instrument panel activates the ‘followme-home’signal and displays the time (in seconds) during which the lights will remain on. (Signal active for 20 sec.)

Activation time increase: When this function is active, every time you flash the headlights, the time the lights remain on is extended for a further 30 seconds (max. 210 sec.)

Deactivation:

-keep the control for flashing the headlights active for over 2 seconds.

-turn the ignition key from OFF to ON.
