Description Of Parameters

PARAMETERS, STATUS 

TESTING OPTICAL FIBERS 

Indicates if the 3 dB switch is on or off.

Normal = the MOST network has normal light intensity.

-3 dB = the MOST network's light intensity is reduced by 3 dB.

NUMBER OF NODES AFTER RING BREAK 

Indicates the status of the result of the ring break diagnostic.

Value set:

OK = diagnostic OK

Diagnosis multimaster = one of more control modules beside the infotainment control module (ICM) thinks it is master node on the MOST network.

Diag all modules slave = all control modules, including the infotainment control module (ICM), consider to be a slave node on the MOST network.

Poor signal = the light intensity is too low for the Infotainment Control Module (ICM) to decode the signal.

Undefined = the infotainment control module (ICM) cannot interpret the result.

MOST LOCKED 

Indicates whether the MOST network is closed and communication possible.

OK = communication possible.

Not OK = communication not possible.

BUTTONS ON CONTROL MODULE 

Indicates if the selected button on the infotainment control module (ICM) is pressed in or not.

EJECT, AM, FM, cd, Mode

Released = the control module interprets the button as not being pressed in.

Pressed in = the control module interprets the selected button as being pressed in.

WARM-UP DISPLAY 

Indicates if the display warm-up has been activated or not. The possible values are:

• Heater not activated
• Heater activated

IR SENSOR 

Indicates if the IR sensor has been activated or not. The possible values are:

• Active
• Not active

STEERING WHEEL BUTTONS 

Indicates if the selected steering wheel button is pressed in or released.

• Navigation - Enter
• Navigation - back
• Yes
• No
• Volume +
• Volume -
• Voice control

Released = the control module interprets the selected button as not being pressed in.

Pressed in = the control module interprets the selected button as being pressed in.

PARAMETERS, VALUE

The measured value indicates the display temperature, in °C.

BUTTON LUMINANCE 

Measurement range 0-100%.

The measured value indicates the relative luminance of the buttons.

LCD LUMINANCE 

Measurement range 0-100%.

The measured value indicates the relative luminance of the display.

NUMBER OF NODES AFTER RING BREAK 

Measurement range: Qty. 0 - 10

Indicates the number of nodes after interference on the MOST network.

POWER SUPPLY, 5 V 

Measurement range: 0-10 V.

Normal range: 4.5 - 5.5 V.

The value indicates the internal power supply in the infotainment control module (ICM).

VOLTAGE SUPPLY CONTROL MODULE 

Measurement range: 0 - 25.5 V.

The value indicates the power supply to the infotainment control module (ICM).
