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
Standard resistance
7 CHECK HARNESS AND CONNECTOR (DOOR CONTROL SWITCH (PASSENGER SIDE) -DRIVER SIDE J/B)
Standard resistance
REPAIR OR REPLACE HARNESS OR CONNECTOR
8 INSPECT FRONT DOOR W/ MOTOR LOCK ASSEMBLY LH

REPLACE DRIVER SIDE JUNCTION BLOCK ASSEMBLY (MULTIPLEX NETWORK BODY ECU)
Initialization procedure
(a) Make sure that the ignition switch is off.
(b) Connect the intelligent tester to the DLC3.
(c) Turn the ignition switch to the ON position.
(d) Select "TIREPRESS" by following the prompts
displayed on the intelligent tester.
(e) Press the tire pressure warning reset sw ...
Data list / active test
1. DATA LIST
Using the intelligent tester to read the Data List allows
the values or states of switches, sensors, actuators and
other items to be read without removing any parts. This
non-intrusive inspection can be very useful because
intermittent conditions or signals may be discovered
befor ...
Park / Neutral Position Switch Circuit
DESCRIPTION
The fold seat control ECU receives signals from the Park/Neutral position
switch and controls the seat
stowing and return operations. If the shift lever is in any position other than
P the seat cannot be operated.
If the ignition switch is in ACC or IG the seat cannot be operate ...
