formatted or in process of uploading or downloading. Or else it may
result in program error.
Precautions on Using X-431 PADII
The ignition switch should be OFF while plugging or unplugging the•
diagnostic connector.
When the diagnostic connector is not used, remember to place•
it into the diagnostic connector housing located on the docking
station to avoid loss.
If your vehicle keeps unattended for a week or a long period, it•
is suggested to unplug the connector from vehicle’s DLC to save
battery power.
While diagnosing a vehicle, you are not advised to use phone•
or messaging, because it may cause a data communication
interruption. If it happens, it is abnormal and just try to re-do it.
Precautions on Operating Vehicle’s ECU
Do not disconnect the vehicle inner consumer when the ignition•
switch is ON. High voltage transients may encounter at the moment
of disconnecting, which may damage the sensors and the ECU.
Protect the computer from magnetic object.•
Do cut off the power supply of ECU system before welding on the•
vehicle.
Pay more attention to the ECU and the sensors when the operation•
is next to them.
Ground yourself when you disassemble PROM, otherwise ECU•
and sensors will be damaged by static electricity.
Do connect ECU harness connector firmly, otherwise electronic•
elements, such as IC inside ECU, will be damaged.

5 How to diagnose
5.1 Connections
5.1.1 Preparation
Normal testing conditions
Turn on the vehicle power supply.•
Vehicle battery voltage range should be 9-14V and working voltage•
of X-431 PADII is 5V.
Throttle should be closed at its close position.•
Ignition timing and idle speed should be within specified range;•
water and transmission oil temperature are within normal working
range (water temperature is 90-110℃and transmission oil
temperature is 50-80℃).
Select testing connectors
If X-431 PADII is testing vehicles equipped with universal OBD II 16
PIN diagnostic socket, please use the included diagnostic connector.
(For vehicles with non-OBD II 16 PIN diagnostic socket, a non-16 PIN
connector is required.)
5.1.2 DLC Location
The DLC (Data Link Connector or Diagnostic Link Connector) is the
standardized 16-cavity connector where diagnostic code readers
interface with the vehicle’s on-board computer. The DLC is usually
located 12 inches from the center of the instrument panel (dash), under
or around the driver’s side for most vehicles. If Data Link Connector 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 for the

location.
Near the center
of dashboard
Fig. 5-1
5.1.3 Vehicle Connection
The method used to connect the diagnostic connector to a vehicle’s
DLC depends on the vehicle’s conguration 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.
Follow the steps mentioned below to connect OBD II vehicle:
Locate vehicle’s DLC socket.1.
Plug the diagnostic connector into the vehicle’s DLC socket (It2.
is suggested to use the OBD II extension cable to connect the
diagnostic connector and DLC socket.).

B. Internal battery pack: For details on how to recharge X-431
PADII, see “Chapter 3.1 Charging X-431 PADII”.
For non-OBDII vehicle, proceed as follows:
Locate vehicle’s DLC socket.1.
Select the corresponding non-16pin connector.2.
Plug the non-16pin end of the connector into the DLC socket, then3.
connect the other end to the OBD I converter, and then tighten the
captive screws.
Connect the other end of the converter to the included diagnostic4.
connector.
To supply power to OBD I converter from:5.
A. Cigarette Lighter: Connect one end of the cigarette lighter cable
to vehicle’s cigarette lighter receptacle, and the other end to the
power jack of OBD I converter.
Fig. 5-2
B. Battery Clamps Cable: Connect one end of the battery clamps
