Description

Combination meter

Judges whether the parking brake is released from the vehicle speed signal received from the 
unified meter and A/C amp. via CAN communication line and the parking brake switch signal from 
the parking brake switch, and sounds the buzzer if necessary.

Unified meter and A/C amp.

Receives a vehicle speed signal from ABS actuator and electric unit (control unit) via CAN com-
munication line and transmits it to the combination meter by means of communication line.
