MODEL 204.0/2 as of model year 2009
MODEL 204.3
MODEL 204.9
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 any faulty or safety-relevant vehicle functions, various warnings are displayed on the instrument cluster.
The following displays are incorporated into the instrument cluster in order to be able to convey information to the driver:
- Permanent displays (e.g. vehicle speed, rotational speed, tank contents)
- Indicator lamps (green, yellow or blue) (e.g. turn signals, high beams)
- Warning lamps (red) (e.g. coolant level, brake fluid level)
- Travel distance display (model 204 (except 204.077/277/377) without code (442) Comfort multifunction steering wheel)
- Multifunction display (with code (442) Comfort multifunction steering wheel, model 204.077/277/377)
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
The following functions are also possible; they are described in separate documents:
- Control/warning messages, function
- Display operating conditions, function
- Comfort displays, function
- Trip computer, function
- Settings on workshop level, function
Function sequence for activate instrument cluster
The background illumination for travel distance display (model 204 (except 204.077/277/377) without code (442) Comfort multifunction steering wheel) or for multifunction display (with code (442) Comfort multifunction steering wheel, model 204.077/277/377) in the instrument cluster is activated in the following events:
- Open or close driver door
- Unlocking vehicle using radio or infrared
- New fault entry with the attribute "Wake display"
- Operation of the button group of the left multifunction steering wheel with circuit 15C On
The scale illumination is also activated by the instrument cluster under the following conditions:
- Standing light on (with instrument cluster without black dial; otherwise always activated)
After switching off circuit 15R, the instrument cluster remains active for t = 30 s. If a fault exists this time is increased to t = 120 s.
Additional function requirements for indicator lamp test
- Circuit 15 On
Function sequence for indicator lamp test
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 electronic ignition lock control unit transmits the status of circuit 15 over the chassis CAN.
The function of the following warning and indicator lamps is checked during the indicator lamp test:
- Fuel reserve indicator lamp
- Seat belt warning lamp
- Supplemental restraint system indicator lamp
- Preglow indicator lamp (on diesel engine)
- Antilock brake system indicator lamp
- ESP OFF indicator lamp (model 204.077/277/377)
- ESP®/ASR warning lamp OFF (as of 1.6.10)
- Electronic Stability Program warning lamp
- Brake system warning lamp
- Coolant temperature warning lamp
- Engine diagnosis indicator lamp
- DISTRONIC warning lamp (with code (233) Distronic Plus)
- Tire pressure monitor warning lamp (with code (470) Tire pressure monitor (standard) or with code (475) Tire pressure monitor (premium), Schrader)
The indicator lamp test is terminated when the engine is started.
The following indicator lamps are not tested:
- Left turn signal indicator light
- Right turn signal indicator light
- High beam indicator lamp
- Rear fog light indicator lamp (as of 1.6.09)
- Standing light indicator lamp (as of 1.6.12 with instrument cluster with black dial)
- Front fog lamp indicator lamp (as of 1.6.09)
- Low beam indicator lamp
Detailed information on the warning and indicator lamps is available in the "Instrument cluster component description" document.
