Description of global parameters

Global parameters

Total Mileage (km)
The value shows the vehicle's total mileage, the same information as normal is shown in the combination instrument. Information is stored in the Central electronic module (CEM) and is distributed to other control modules via the communication network that connects the Central electronic module (CEM) and the current control module, e.g., CAN.

Total mileage (miles)
The value shows the vehicle's total mileage, the same information as normal is shown in the combination instrument. Information is stored in the Central electronic module (CEM) and is distributed to other control modules via the communication network that connects the Central electronic module (CEM) and the current control module, e.g., CAN.

MECU power supply (V)
The value shows the level of voltage feed from the battery to the Central electronic module (CEM). Information is stored in the Central electronic module (CEM) and is distributed to other control modules via the communication network that connects the Central electronic module (CEM) and the current control module, e.g., CAN.
Normal range: 12.0 - 14.5 V.

Passenger compartment temperature (°C)
The value shows the passenger compartment temperature. The information originally comes from a temperature sensor connected to the climate control module (CCM) and is sent on to the Central electronic module (CEM) via CAN. Information is stored in the Central electronic module (CEM) and is distributed to other control modules via the communication network that connects the Central electronic module (CEM) and the current control module, e.g., CAN.

Outside temperature (°C)
The value shows the external temperature. The information originally comes from a temperature sensor connected to the Engine control module (ECM) and is sent on to the Central electronic module (CEM) via CAN. Information is stored in the Central electronic module (CEM) and is distributed to other control modules via the communication network that connects the Central electronic module (CEM) and the current control module, e.g., CAN.

Power supply mode (status)
The status shows the vehicle's power supply mode. Central electronic module (CEM) collects information from relevant control modules and sensors, and generates the parameter. Information is stored in the Central electronic module (CEM) and is distributed to other control modules via the communication network that connects the Central electronic module (CEM) and the current control module, e.g., CAN.
