Component Description For Instrument Cluster - GF54.30-P-6000KJE
MODEL 453.091/391/491 with CODE K35 (Instrument cluster with monochrome display)
MODEL 453.091/391/491 with CODE K36 (Instrument cluster with color 8.9 cm (3.5") display)
Shown: instrument cluster (A1) with code K36 (Instrument cluster with color 8.9 cm (3.5") display) without code 494 (USA version)
The following components integrated in the instrument cluster are not shown:
- Warning buzzer (A1h1)
- Function check of turn signal lights, acoustic (A1h2)
Location
The instrument cluster is located in the dashboard on the driver-side.
Task
The instrument cluster has the following tasks:
- Reading in of sensors and signals
- Evaluation of input factors
- Actuation of components
- Output of warning tones and indicator tones
- Output of signals
Reading in of sensors and signals
The signals are read in by the instrument cluster.
The instrument cluster reads in the input factors via the following connections:
- Interior CAN (CAN B)
- Direct line
Interior CAN
The signals are read in by the instrument cluster over the interior CAN.
The functions that use these signals are described in the individual function descriptions (see appropriate block diagram or function schematic).
Direct line
The functions that use these signals are described in the individual function descriptions (see appropriate block diagram or function schematic).
The following sensors are read in directly:
- Outside temperature sensor (M21/2b1)
- Menu navigation button group (S4/5)
- Brake fluid level switch (S11)
- Parking brake indicator switch (S12)
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.
Actuation of components
The instrument cluster directly actuates all internal actuators (e.g. indicator and warning lamps, stepper motors of displays, multifunction display) as well as the instrument illumination.
Output of warning tones and indicator tones
To issue warning and alert tones requested by the systems installed in the vehicle, the instrument cluster actuates the warning buzzer or the acoustic function check for turn signal lights (issue of turn signal ticking) directly.
Output of signals
The signals are issued over the following connections:
- Additional instrument-LIN (LIN B22)
- Interior CAN
Additional instruments LIN
The signals are sent by the instrument cluster via the additional instrument LIN.
The functions that use these signals are described in the individual function descriptions (see appropriate block diagram or function schematic).
Interior CAN
The signals are sent by the instrument cluster over the interior CAN.
The functions that use these signals are described in the individual function descriptions (see appropriate block diagram or function schematic).
