4.3.2 DLC location

The DLC (Data Link Connector) is typically a standard 16-pin connector where
diagnostic tools interface with a vehicle’s on-board control modules. The DLC is
usually located 12 inches from the center of the instrument panel, under or
around the driver’s side for most vehicles. If DLC is not located under dashboard,
a label should be there telling location. For some Asian and European vehicles,
the DLC is located behind the ashtray and the ashtray must be removed to
access the connector. If the DLC cannot be found, refer to the vehicle’s service
manual.

4.3.3 Vehicle connection

The method used to connect the VCI device to a vehicle’s DLC depends on the
vehicle’s configuration as follows:

 A vehicle equipped with an OBD II management system supplies both

communication and 12V power through a standardized DLC.

 A vehicle not equipped with an OBD II management system supplies

communication through a DLC connection, and in some cases supplies 12V
power through the cigarette lighter receptacle or a connection to the vehicle
battery.

5.7

n immobilizer is an anti-theft mechanism that prevents a vehicle’s engine from

A
starting unless the correct ignition key or other device is present. Most new
vehicles have an immobilizer as standard equipment. An important advantage of
this system is that it doesn’t require the car owner to activate it since it operates
automatically. An immobilizer is considered as providing much more effective
anti-theft protection than an audible alarm alone.

As an anti-theft device, an immobilizer disables one of the systems needed to
start a car’s engine, usually the ignition or the fuel supply. This is accomplished
by radio frequency identification between a transponder in the ignition key and a
device called a radio frequency reader in the steering column. When the key is

36

LAUNCH

placed in the ignition, the transponder sends a signal with a unique identification
code to the reader, which relays it to a receiver in the vehicle’s computer control
module. If the code is correct, the computer allows the fuel supply and ignition
systems to operate and start the car. If the code is incorrect or absent, the
computer disables the system, and the car will be unable to start until the correct
key is placed in the ignition.

To prevent the car being used by unauthorized keys, the anti-theft key matching
function must be performed so that the immobilizer control system on the car
identifies and authorizes remote control keys to normally use the car.

When the ignition switch key, ignition switch, combined instrument panel, ECU,
BCM, or remote control battery is replaced, anti-theft key matching must be
performed.

Injector Coding

This function enables you to perform a resetting operation on the monitoring unit

cleared and battery matching will be done.

Battery matching must be performed in the following cases:

a) Main battery is replaced. Battery matching must be performed to clear

original low battery information and prevent the related control module from
detecting false information. If the related control module detects false
information, it will invalidate some electric auxiliary functions, such as
automatic start & stop function, sunroof without one-key trigger function,
power window without automatic function.

b) Battery monitoring sensor. Battery matching is performed to re-match the

control module and motoring sensor to detect battery power usage more
accurately, which can avoid an error message displaying on the instrument
panel.
