Description of frozen values

Explanation
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.

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

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

Power supply position, status
The value indicates the current status of the power supply position when the diagnostic trouble code (DTC) was stored.

Tow hitch connector connected, status
The value indicates if the trailer module (TRM) registers that the tow hitch connector is connected when the diagnostic trouble code (DTC) was stored.
Yes = tow hitch connector is connected.
No = tow hitch connector is not connected.

Back-up (reversing) lamp, status
The value indicates if the trailer module (TRM) has activated the signal for the back-up (reversing) lamp when the diagnostic trouble code (DTC) was stored.
On = back-up (reversing) lamp activated.
Off = back-up (reversing) lamp not activated.

Fog lamp, status
The value indicates if the trailer module (TRM) has activated the signal for the fog lamp when the diagnostic trouble code (DTC) was stored.
On = fog lamp activated.
Off = fog lamp not activated.

Parking lamps, status
The value indicates if the trailer module (TRM) has activated the signal for the parking lamp when the diagnostic trouble code (DTC) was stored.
On = parking lamps activated.
Off = parking lamps not activated.

Right-hand stop lamp, status
The value indicates if the trailer module (TRM) has activated the signal for the right-hand stop lamp when the diagnostic trouble code (DTC) was stored.
On = right-hand stop lamp activated.
Off = parking lamps not activated.

Left-hand stop lamp, status
The value indicates if the trailer module (TRM) has activated the signal for the left-hand stop lamp when the diagnostic trouble code (DTC) was stored.
On = left-hand stop lamp activated.
Off = left-hand stop lamp not activated.

Stop lamp input signal, status
The value indicates if the trailer module (TRM) receives an input signal for the stop lamp from the central electronic module (CEM) when the diagnostic trouble code (DTC) was stored.
On = input signal for stop lamp received.
Off = input signal for stop lamp not received.

Right-hand turn signal lamp, status
The value indicates if the trailer module (TRM) has activated the signal for the right-hand turn signal lamp when the diagnostic trouble code (DTC) was stored.
On = right-hand turn signal lamp activated.
Off = right-hand turn signal lamp not activated.

Left-hand turn signal lamp, status
The value indicates if the trailer module (TRM) has activated the signal for the left-hand turn signal lamp when the diagnostic trouble code (DTC) was stored.
On = left-hand turn signal lamp activated.
Off = left-hand turn signal lamp not activated.
