Instrument Cluster

Instrument Cluster




The instrument cluster incorporates the five familiar analog gauges along with indicator/warning lights and Liquid Crystal Displays.

All the indicator/warning lights are LEDs and are not replaceable. Critical warning indicators use two LEDs for safety. There are five conventional bulbs for the back lighting of the LCD which can be replaced if necessary.




The LCD provides:
- 6 digit total mileage
- 4 digit trip mileage
- Manipulation DOT
- Outside temperature display
- 20 digit read-out with reminder arrows
- Service Interval Indicator
- Automatic transmission selector position
- Automatic transmission driving program

When KLR is switched on, mileage and temperature are displayed. All displays are illuminated from KL15.

The back lighting intensity of the LCD's is dependent on available light and is controlled by a photo-transistor in the lower left corner of the cluster. When the parking lights are switched on, the dash mounted dimmer wheel controls the intensity of the back lighting.

Service Interval Indicator (SIA)




The Service Interval Indicator of the E38 up to M.Y. 96' operates using SIA II. SIA III is used after M.Y. 96' to present vehicles.

The reset of Service Indicator is carried out with the reset tool, DIS, or cluster reset mode (reset mode after 9/00 only).

Total Mileage/Trip Mileage
Mileage can be displayed with the key off for 25 seconds if the trip meter button is pressed.

Total mileage is stored in non-volatile memories of the IKE and LCM to protect against loss.

Automatic Transmission Selector Position/Driving Program




As introduced, the selector lever position and driving program were signaled to the IKE from the AGS control module over a single wire circuit. These signals are passed along by the CAN after the CAN bus was connected to the integrated IKE.

Analog Instruments
Analog instruments are controlled by the IKE from signals it receives over separate inputs or the CAN bus.
