CreaderVII English User’' s Manual
1. INTRODUCTION
The CreaderVII is a game changer in the world of portable Automotive Diagnostics. Is it a
code scanner, or is it a scan tool? The CreaderVII blurs the lines by being the first full
color, 4 PID graphing code scanner in the market. The CreaderVII boasts an industry
leading 2 frames per second data capture, while having the ability to store, record and
playback over 29 data files, lasting over 8 hours! The CreaderVII is also very easy to use.
With built-in help menus and code definitions, diagnosing and repairing that dreaded
Check Engine Light is now easier than ever! And we don’'t stop there. The CreaderVII
also features the following bi-directional “"special tests”": EVAP, 02 Sensor, I/M Readiness,
MIL Status, VIN Info, and On-board monitors testing.

BEING DISTURBED BY STRONG STATIC ELECTRICITY. THIS
IS A NORMAL REACTION.
2. General Information-About OBDII/EOBD
2.1 On-Board Diagnostics (OBD) II
The first generation of On-Board Diagnostics (called OBD I) was developed by the
California Air Resources Board (ARB) and implemented in 1988 to monitor some of the
emission control components on vehicles. As technology evolved and the desire to
improve the On-Board Diagnostic system increased, a new generation of On-Board
Diagnostic system was developed. This second generation of On-Board Diagnostic
regulations is called "OBD II".
The OBD II system is designed to monitor emission control systems and key engine
components by performing either continuous or periodic tests of specific components and
vehicle conditions. When a problem is detected, the OBD II system turns on a warning
lamp (MIL) on the vehicle instrument panel to alert the driver typically by the phrase of
“"Check Engine”" or “"Service Engine Soon”". The system will also store important
information about the detected malfunction so that a technician can accurately find and fix
the problem. Here below follow three pieces of such valuable information:
1) Whether the Malfunction Indicator Light (MIL) is commanded 'on' or 'off';
2) Which, if any, Diagnostic Trouble Codes (DTCs) are stored;
3) Readiness Monitor status.
2.2 Diagnostic Trouble Codes (DTCs)
OBD II Diagnostic Trouble Codes are codes that are stored by the on-board computer
diagnostic system in response to a problem found in the vehicle. These codes identify a
particular problem area and are intended to provide you with a guide as to where a fault
might be occurring within a vehicle. OBD II Diagnostic Trouble Codes consist of a
five-digit alphanumeric code. The first character, a letter, identifies which control system
