IMMOBILIZER SYSTEM 11A-3

General Description
The immobilizer system consists of the four major
components which are Engine Control Module (ECM),
Immobilizer Control Unit (lCU), transponder, and scan
tool (Tech-2).
This system can be activated by a correctly programmed
transponder and starter switch is set to OFF.
This system can be deactivated by a correctl
y
programmed transponder key connected with a correctly
programmed ECM and a correctly programmed lCU.
While the system is on :
The starter cut off relay deactivates function of starter,
and the fuel injector power source is deactivated also.


Check Engine lamp is flashing.


Warning buzzer is operating.
(With antitheft system)

IMMOBILIZER SYSTEM 11A-13

Immobilizer control unit (ICU);
Mechanical Control Engine (4JA1-T)
Immobilizer control unit (ICU) permits engine starting,
when the security code which compares the securit
y
code registered into the transponder (key) and the
security code registered into ICU, and is similarl
y
registered into ICU and engine immobilizer unit (DDS-1)
is compared and it is judged that it is normal. When the
code registered into the key is unusual, and when not
recognizing a security code, engine immobilizer unit
does not permit starting of engine by the fuel cut valve
on the fuel pump.
The engine immobilizer unit is located with fuel cut
valve on fuel pump 4JA1-T engine.
The immobilizer control unit decides whether there is an
abnormality the security code based on the engine
immobilizer unit security code.
When the problem found, the engine immobilizer unit
stops fuel fupply by the fuel cut valve.

TRANSFER CASE 7D-3

General Description

RUW34DLF000701
The transfer case is used to provide a means of
providing power flow to the front axle. The transfer case
also provides a means of disconnecting the front axle,
providing better fuel economy and quieter operation
when the vehicle is driven on improved roads where
four wheel drive is not required. In addition, the transfer
case provides an additional gear reduction when placed
in low range, which is useful when difficult off-road
conditions are encountered.
Use the 4WD switch on the center cluster panel to
select the drive range. The 4WD indicator lamp will be
lit when 4WD is selected.
