ON-VEHICLE INSPECTION
1. INSPECT AIR INLET CONTROL SERVO MOTOR
(a) Remove the air inlet control servo motor.
(b) Connect the positive (+) lead from the battery to
terminal 5 and negative (-) lead to terminal 1, then
check that the lever turns to "RECIRCULATION"
side smoothly.

Rear Clearance Sonar Sensor LH Circuit
DESCRIPTION
An ultrasonic sensor consists of a sensor portion that transmits and receives
ultrasonic waves and a preamplifier
that amplifies them. The ultrasonic sensor outputs the ultrasonic waves and
sends the received
signals to the clearance warning ECU.
