Instrument Cluster (IC), Function - GF54.30-P-0002KJE
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 with code 252 (Distance warning function)
Instrument cluster, general
The instrument cluster notifies the driver of all dynamic and static driving conditions as well as about the current condition of the systems installed in the vehicle.
In the event of faulty vehicle functions or functions relevant to safety, corresponding warnings are issued via the instrument cluster.
To provide the driver with information, the following indicators are installed in the instrument cluster:
- Permanent displays (e.g. speed)
- Indicator lamps (green, yellow or blue) (e.g. turn signals, high beams)
- Warning lamps (red, yellow) (e.g. coolant level, brake fluid level)
- Multifunction display (e.g. outside temperature indicator, travel distance display)
The function description for the "Instrument cluster (KI) function" contains the following functions:
- Function sequence for activate instrument cluster
- Function sequence for indicator lamp test
Further functions are described in separate documents:
- Control/warning messages, function
- Display operating conditions, function
- Comfort displays, function
- Trip computer, function
Function sequence for activate instrument cluster
If the following events occur, the default screen is activated in the multifunction display of the instrument cluster:
- Unlocking of the vehicle
- Driver door opened
- Change of circuit status for circuit 15
If the following events occur, the default screen in the multifunction display and the scale illumination of the instrument cluster are activated:
- Standing lamps ON
Function sequence for indicator lamp test
Additional function requirements for indicator lamp test
- Change of status from circuit 15R to circuit 15
Immediately prior to the indicator lamp test, the pointer of the speedometer is illuminated and moves within a defined range, 2/3 of the maximum possible deflection.
The indicator lamp test serves the function test of certain warning lamps and indicator lamps in the instrument cluster. The instrument cluster carries out this test automatically each time circuit 15 is switched on.
The function of the following warning and indicator lamps is checked during the indicator lamp test:
- SRS indicator lamp
- Anti-lock braking system indicator lamp
- ESP® warning lamp
- Distance warning function indicator lamp (for distance warning function)
- Brake fluid and parking brake warning lamp
- Power steering warning lamp
- Tire pressure monitor warning lamp
- Door OPEN warning lamp
- Drive diagnosis warning lamp
- Charging cable indicator lamp
The indicator lamp test is terminated when the engine is started.
Detailed information about actuation of the warning and indicator lamps is given in the separate document "Instrument cluster, component description".
