Rear Left Center Sensor Malfunction (C1AE7)
DESCRIPTION
The No. 1 ultrasonic sensor (rear center sensor LH) is installed on the rear
bumper. The ECU detects obstacles based on signals received from the No. 1 ultrasonic
sensor (rear center sensor LH). If the No. 1 ultrasonic sensor (rear center sensor
LH) has an open circuit or other ma ...
