DESCRIPTION
The body ECU receives a switch signal from the master switch, the door control switch, the driver door key cylinder and the passenger door key cylinder and then drives the door lock motor.

INSPECTION PROCEDURE
1 INSPECT FUSE (ECU-B)
Standard resistance: Below 1 Ω
2 PERFORM ACTIVE TEST BY INTELLIGENT TESTER
HINT: During the ACTIVE TEST, the intelligent tester sends a signal to the body ECU to drive all the power door lock motors. If the power door lock operates, the power door lock motor itself and the wire harness between the power door lock motor and body ECU are considered to be functioning normally.
BODY (Multiplex network body ECU)
3 CHECK OPERATION (MASTER SWITCH OR KEY CYLINDER)
4 INSPECT POWER WINDOW REGULATOR SWITCH ASSEMBLY (DOOR CONTROL SWITCH)
Standard resistance
5 CHECK HARNESS AND CONNECTOR (POWER WINDOW REGULATOR MASTER SWITCH - DRIVER SIDE J/B)
Standard resistance
REPAIR OR REPLACE HARNESS OR CONNECTOR
6 INSPECT DOOR CONTROL SWITCH ASSEMBLY

Front 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.

Diagnosis system
1. CHECK DLC3
The vehicle's ECU uses ISO 15765-4 for
communication protocol. The terminal arrangement
of the DLC3 complies with SAE J1962 and matches
the ISO 15765-4 format.
NOTICE:
*: Before measuring the resistance, leave the
vehicle as is for at least 1 minute and do ...
