Description of frozen values

Description

Frozen values are parameter values that are stored when a diagnostic trouble code (DTC) is stored.
Not all parameters can be read off for all diagnostic trouble codes (DTCs). The parameter values can only be read off where they can provide more information about the prevailing circumstances when the diagnostic trouble code (DTC) was stored.

Parameters, value

Total mileage
Measurement range: 0 -1,000,000 km.
The value indicates the vehicle's total mileage when the Diagnostic Trouble Code (DTC) was generated.

MECU power supply
Measurement range: 0 -63 V.
Normal range: 12.0 -14.5 V.
The value indicates the supply voltage to the central electronic module (CEM) when the diagnostic trouble code (DTC) was stored.

Passenger compartment temperature
Measurement range: -40 to +215 °C.
The value indicates the passenger compartment temperature when the diagnostic trouble code (DTC) was stored.

Outside temperature
Measurement range: -40 to +215 °C.
The value indicates the outside temperature when the diagnostic trouble code (DTC) was stored.

Power supply position
The value indicates the current status of the power supply position when the diagnostic trouble code (DTC) was stored.
Key removed.
Key recently removed.
-Key approved.
Ignition off after Accessory position.
Accessory position.
Accessory position after Ignition on.
Ignition on.
Running.
Start attempts.

Status- Air quality sensor
Indicates the status of the air quality.
Value set:
Level 0 = no increase or decrease in pollutant level.
Level 1 = slow increase in pollutant level.
Level 2 = medium increase in pollutant level.
Level 3 = rapid increase in pollutant level.
Warm-up phase = the sensor is heated.
Defective heater pad = Warm-up of the sensor does not function correctly.
Stand-by mode = The sensor is not active.

Requested blower fan speed
Measurement range 0 to 100%.
Indicates the requested speed of the fan.

Voltage supply control module
Measurement range 0 to 25.5 V.
The value indicates the power supply to the climate control module (CCM) when the diagnostic trouble code (DTC) was stored.
