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.

GLOBAL TIME 

The value shows the time since the Central Electronic Module (CEM) was supplied with voltage the first time. Transmission Control Module (TCM) obtains the value via the CAN-net from Central Electronic Module (CEM). The value is given in minutes.

TOTAL MILEAGE, VALUE 

Measurement range: 0 -16, 777, 215 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.

POWER SUPPLY POSITION, STATUS (BEFORE STRUCTURE WEEK 201046) 

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 attempt
• Signal missing

POWER SUPPLY POSITION, STATUS (AFTER STRUCTURE WEEK 201046) 

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
• Combustion engine running
• Combustion engine in auto-stop
• Combustion engine in start attempt
• Combustion engine in start attempt at manual start

ECU POWER SUPPLY 

Measurement range: 0 - 25.5 V.

Indicates the supply voltage to the Closing velocity module (CVM) when the diagnostic trouble code (DTC) was stored.

INTERNAL TEMPERATURE, VALUE 

Measurement range: -40 to 215 °C.

Indicates the internal temperature in the Closing velocity module (CVM) when the diagnostic trouble code (DTC) was stored.

VEHICLE SPEED 

Indicates the vehicle speed (km/h) when the diagnostic trouble code was stored. In the event of a negative value, reverse gear was engaged when the diagnostic trouble code was stored.
