125000412 - 5560B ANALOGUE CONTROL PANEL
SPECIFICATIONS
INTRODUCTION
The instrument panel is inside the B-CAN and is called the NQS (Instrument Panel Node).The signals concerned with systems on the C-CAN are made available to the NQS by the Body Computer Node via an interface known as a Gateway.The task of the NQS is to display the vehicle operating parameters and to notify the driver of any possible faults in the on-board electronic systems.The instrument panel includes a TN LCD display and a reconfigurable DSTN dot-matrix display (HIGH version).Some specifications are fitted with a LOW version with two TN LCD displays.

Diagnosis
The diagnosis of the instrument panel can be carried out using the diagnostic equipment available in the network (Examiner or Examiner plus).The diagnostic socket is located in the EOBD, the line used is the B-CAN line.The following operations are included in the diagnosis:
- Display of possible errors present in the instrument panel,
- Memorizing milometer mileage.
- Set kilometres for the SERVICE function (instrument panel replacement)
- Carry out the active diagnosis in order to check the operation of the instrument panel
| When the panel is replaced the alignment of the PROXI should always be carried out (using the specific program); if it is not, then the mileometer will flash and the panel will not be fully operational. |
OPERATION
The task of the instrument panel node is to:
- Receive and transmit information on the B-CAN
- Manage the accessory functions.
- Receive and manage signals not from network
- Display the vehicle operating statuses
SPEEDOMETER
The instrument panel receives speed information, expressed in km/h, via the B-CAN line and then displays it by means of a pointer which is moved by a step motor.The speed information comes from the NBC and the latter calculates the speed using the wheel rpm signal from the NFR (ABS) and measurement of the wheel circumference memorized in the NBCThe pointer remains stationary, in the rest position, at speeds of between 0 and 4 km/h. The speed signal received is shown at higher speeds.Error conditions
In case of error, the speedometer pointer will position itself on the zero speed notch (rest position) and remain in this position for as long as the fault persists.Speed limit (only high version)
It is possible set a speed limit from the Menu, with a range from 30 to 250 km/h
ODOMETER
The display contains 7 segments and is configured as a quasi dot matrix to obtain a dot matrix-like configuration.
