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

Shift position purpose
*1: Shifting to the D position allows the system to select a gear suitable
for
the driving conditions. Setting the shift lever to the D position is recommended
for normal driving.
*2: Selecting shift ranges using S mode restricts the upper limit of the
possible
gear ranges, controls en ...
Brake Switch "B" Circuit High
DESCRIPTION
The purpose of this circuit is to prevent the engine from stalling while
driving in lock-up condition when
brakes are suddenly applied.
When the brake pedal is depressed, this switch sends a signals to the ECM. Then
the ECM cancels the
operation of the lock-up clutch while ...

FOR VEHICLES EQUIPPED WITH MOBILE COMMUNICATION SYSTEMS
(a) Install the antenna far away from the ECU and
sensors of the vehicle electronic systems as
possible.
(b) Install an antenna feeder at least 20 cm (7.87 in.)
away from the ECU and sensors of the vehicle
electronic systems. For de ...
