Circuit Description
The provision for communicating with the ECM is the Data Link Connector (DLC). It is located in the instrument panel
fuse block. The DLC is used to connect the scan tool. Battery power and ground is supplied for the scan tool through
the DLC. CAN line is used to communicate with the other module such as the Transmission Control Module (TCM) and
Transfer Case Control Unit (TCCU).
Keyword 2000 Serial Data Communications
Each bit of information can have one of two lengths: long or short. This allows vehicle wiring to be reduced by transmit-
ting and receiving multiple signals over a singles wire. The message carried on KWP 2000 data streams are also priori-
tized. If two messages attempt to establish communications on the data line at the same time, only the message with
higher prioritywill must wait.

Circuit Description
Immobilizer is a device disabling vehicle ignition unless a specific key is used and designed to help prevent vehicle
theft.
Immobilizer is comprised of two devices, a key with encoded transponder and ECM with the same encoding of the
transponder. When a key is inserted into the hole to start vehicle and turned to ON, the ECM reads and decodes the
transponder code and, if the same, starts the engine, it is called immobilizer. It means immobilizersystem disables
starting by stopping fuel supply if the code in the transponder does not match the code stored in ECM each other.

Notice
The sealing lip of the repair radial seal is offset to the
inside by 2mm to ensure that is does not run in any
groove which the standard radial seal may have left
on the crankshaft flange.

Replacement Procedure
1. Pull out the radial seal (1) and be careful not to dam-
age the sealing surface of timing case cover.
2. Thoroughly clean the mounting bore of the radial
seal.
3. Coat a little oil on the sealing lip of new radial (1) and
contact surface.
Notice
Don’t use grease.
4. Install the radial seal (1) by using a sleeve (4).
Notice
Align the groove of sleeve and woodruff key(arrow).
