DESCRIPTION

• ABS actuator and electric unit (control unit) transmits a vehicle speed signal to the combination meter via

CAN communication. 

• The combination meter receives the vehicle speed signal from the ABS actuator and electric unit (control

unit) with CAN communication line and transmits it to the upper meter by means of communication line.

• The upper meter indicates the vehicle speed according to the vehicle speed signal received from the combi-

nation meter by means of communication line.

DESCRIPTION

• The following power levels can be checked on the power meter of the combination meter:

- Current motor power

- Maximum motor output power

- Maximum regenerable power

• VCM sends the signals below to the combination meter via CAN communication.

- Current motor power signal

- Maximum motor output power signal

- Maximum regenerable power signal

• Based on the signals received via CAN communication from VCM, the combination meter displays the

power levels on the power meter.
