 No. 1 Clearance Warning Buzzer Circuit

DESCRIPTION This circuit consists of the No. 1 clearance warning buzzer and clearance warning ECU assembly. An ECU-excited type buzzer is used. The ECU operates the buzzers using a sound pattern that changes depending on the distance to the obstacle. WIRING DIAGRAM PROCEDURE 1. PERFORM ACTIVE

 Open in Rear Door Electrical Antenna Circuit, Front Passengers Side (B27A4)

DESCRIPTION The certification ECU (smart key ECU assembly) generates a request signal and transmits the signal to the rear door outside handle assembly (for front passenger side) (electrical key antenna) at intervals of 0.25 seconds. For the rear door outside handle assembly (for front passenger sid
