P54.33-4963-75

P54.33-A013-75

 Model 205, 253
with code 464 (Full display digital instrument cluster)
The symbols available on the analog display as indicator and warning lamps are shown accordingly on the digital full display.

Location

The instrument cluster is located in the dashboard on the driver-side.

Tasks

The instrument cluster has the following tasks:

 Reading in of sensors and signals

 Evaluation of input factors

 Output of warning tones and indicator tones

 Output of signals

Reading in of sensors and signals

The instrument cluster reads in information and data via the following connections:

 User interface CAN (CAN HMI)

 High-speed video link (HSVL)

User interface CAN

The signals are read in by the instrument cluster via user interface CAN.

High-speed video link

The instrument cluster is connected to the head unit (A26/17) via a HSVL line. Via this interface, the instrument cluster receives map data from the head unit.

Evaluation of input factors

The input factors that have been read in are evaluated by the integrated microprocessor and the relevant components are then actuated.

Output of warning tones and indicator tones

The instrument cluster actuates the instrument cluster speaker (H4/61) in the driver footwell to output warning and indicator tones which are requested by the systems installed in the vehicle.

Output of signals

The instrument cluster sends information and data over the following connections:

 User interface CAN

 High speed video link (with code 463 (Head-up Display))

User interface CAN

The instrument cluster transmits information and data via user interface CAN to various control units.

 If cooling is required, the instrument cluster reports this over the user interface CAN to the head unit, which then activates the jointly used fan. The fan's air flow is distributed between the head unit and the instrument cluster.

High speed video link (with code 463 (Head-up Display))

The instrument cluster is connected to the head-up display (A40/12) via a HSVL line. Via this interface, the instrument cluster sends signals for the displays and illustrations shown on the head-up display.

Variants

 Entry CLASSIC (2-tube, analog) (except code 464 (Digital instrument cluster full display))

 High Traditional (2-tube, digital (virtual)) (with code 464 (Digital instrument cluster full display))

On vehicles with code 464 (Digital instrument cluster full display), the right and center display areas of the instrument cluster can be programmed freely.
