PARKING BRAKE RELEASE WARNING CHIME : System Description

INFOID:0000000003135092

DESCRIPTION

• The unified meter and A/C amp. receives the vehicle speed signal from the ABS actuator and electric unit

(control unit) via CAN communication line and transmits it to the combination meter by means of communi-
cation line.

• The combination meter judges whether the parking brake is released from the vehicle speed signal received

from the unified meter and A/C amp. and the parking brake switch signal from the parking brake switch, and
sounds the warning buzzer if necessary.

WARNING OPERATION CONDITIONS

If all of the following conditions are fulfilled.
• Vehicle speed is 7 km/h (4.3 MPH) or higher
• Parking brake switch ON
