1. Safety Precautions and Warnings
To prevent personal injury or damage to vehicles and/or the CS602, please read
this user’s manual first carefully and observe the following safety precautions
at a minimum whenever working on a vehicle:
zAlways perform automotive testing in a safe environment.
zWear safety eye protection that meets ANSI standards.
zKeep clothing, hair, hands, tools, test equipment, etc. away from all moving
or hot engine parts.
zOperate the vehicle in a well-ventilated work area: Exhaust gases are
poisonous.
zPut blocks in front of the drive wheels and never leave the vehicle unattended
while running tests.
zUse extreme caution when working around the ignition coil, distributor cap,
ignition wires and spark plugs. These components create hazardous voltages
when the engine is running.
zPut the transmission in P (for A/T) or N (for M/T) and make sure the parking
brake is engaged.
zKeep a fire extinguisher suitable for gasoline/chemical/ electrical fires
nearby.
zDon’t connect or disconnect any test equipment while the ignition is on or the
engine is running.
zKeep the CS602 dry, clean, free from oil/water or grease. Use a mild
detergent on a clean cloth to clean the outside of the CS602, when necessary.
2. Introduction
The CS602 is newly developed by CODESCAN, specially designed for car owners
or DIYs to diagnose and vehicle that is compliant to OBDII/EOBD. It not only can
reade/clear DTCs, but also can read live data in 2 modes, and perform mant special
tests. Tri-language make it operation easily for technician. The feature of upgrading
online ensures it can test new model cars and/or functions in the future.
NOTICE: CS602 MAY AUTOMATICALLY RESET
WHILE BEING DISTURBED BY STRONG STATIC
ELECTRICITY. THIS IS A NORMAL REACTION.

3.1 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.
3.2 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 sets the code. The second character, a number, 0-3;
other three characters, a hex character, 0-9 or A-F provide additional information on
where the DTC originated and the operating conditions that caused it to set. Here
below is an example to illustrate the structure of the digits:

3.3 Location of the Data Link Connector (DLC)
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.

after an appropriate drive cycle has been performed. The drive cycle that enables a
monitor and sets readiness codes to “Ready” varies for each individual monitor.
Once a monitor is set as “Ready” or “Complete”, it will remain in this state. A
number of factors, including erasing of diagnostic trouble codes (DTCs) with a code
reader or a disconnected battery, can result in Readiness Monitors being set to “Not
Ready”. Since the three continuous monitors are constantly evaluating, they will be
reported as “Ready” all of the time. If testing of a particular supported
non-continuous monitor has not been completed, the monitor status will be reported
as “Not Complete” or “Not Ready.”

is to alert the driver and/or the repair technician that there is a problem with one or
more of vehicle's systems and may cause emissions to exceed federal standards. If
the MIL illuminates with a steady light, it indicates that a problem has been detected
and the vehicle should be serviced as soon as possible. Under certain conditions, the
dashboard light will blink or flash. This indicates a severe problem and flashing is
intended to discourage vehicle operation. The vehicle onboard diagnostic system

has been disconnected. Running through a vehicle’s complete drive cycle will “set”
the readiness monitors so that future faults can be detected. Drive cycles vary
depending on the vehicle and the monitor that needs to be reset. For vehicle specific

4.6 Vehicle Coverage
The CS602 is specially designed to work with all OBD II compliant vehicles,
including Control Area Network (CAN). It is required by EPA that all 1996 and
newer vehicles (cars and light trucks) sold in the United States must be OBD II
compliant and this includes all American,Asian and European vehicles.
A small number of 1994 and 1995 model year gasoline vehicles are OBD II
compliant. To verify if a 1994 or 1995 vehicle is OBD II compliant, check the
Vehicle Emissions Control Information (VECI) Label, which is located under the
hood or by the radiator of most vehicles. If the vehicle is OBD II compliant, the
label will designate “OBD II Certified”. Additionally, Government regulations
mandate that all OBD II compliant vehicles must have a “common” sixteen-pin Data
Link Connector (DLC).
For the vehicle to be OBD II compliant it must have a 16-pin DLC (Data Link
Connector) under the dash and the Vehicle Emission Control Information Label must
state that the vehicle is OBD II compliant.
