Important Safety Information
To prevent personal injury or damage to vehicles and/or the Scan Tool, read this
instruction manual first and observe the following safety precautions, at a minimum,
whenever working on a vehicle:
1. Always perform automotive testing in a safe environment.
2. Wear safety eye protection.
3. Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot
engine parts.
4. Operate the vehicle in a well ventilated work area. Exhaust gases are poisonous.
5. Put blocks in front of the drive wheels and never leave the vehicle unattended while
running tests.
6. Use 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.
7. Put the transmission in PARK (for automatic transmission) or NEUTRAL (for manual
transmission) and make sure the parking brake is engaged.
8. Keep a fire extinguisher suitable for gasoline/ chemical/ electrical fires nearby.
9. Don't connect or disconnect any test equipment while the ignition is on or the engine
is running.
10. Keep the Scan Tool dry, clean, free from oil, water or grease. Use a mild detergent on
a clean cloth to clean the outside of the Scan Tool, when necessary.

NOTE: If no increase rev detected, it shall be the fault of generator regulator or connection
with battery failed. Testerwill try 3 times to further detect, if still failed, it will skip the increase
rev detect and the test result displays "No Volt Output". See below:
Check the connection between generator and battery, then retest.
Charging Test Result
1. Charging Volt: Normal
Charging system shows the generator
output is normal, and no problem is
detected.
2. Charging Volt: Low
Charging volt of the charging system is
low.
Check drive belt of the generator
whether it is slipping or running off.
Check the connection between
generator and battery is normal or not. If
both of the drive belt and the connection
are in good condition, follow the
manufacturer's suggestion to eliminate
generator fault.
3. Charging Volt: High
Generator output volt is high.
Since most of the vehicle generators are
using internal regulator, the generator
assembly has to be replaced.(Some old
style cars are using external regulator,
then directly replace the regulator.)
The normal high volt of the voltage
regulator is maximum 14.7±0.5V.If
charging volt is too high, it will
overcharge the battery. Therefore the
battery life will be shortened and troubles
will be caused.
4. No Volt Output:
No generator volt output is detected.
Check the generator connection cable
and the belt whether they are normal.
5. Diode Test:
Through the test of charging current
ripple, tester will find out whether the
diode is normal or not. When ripple volt
is too high, it proves at least one diode is
damaged. Check and replace the diode.
Till now, all tests have been done.

Overview
OBD II On-Board Diagnostics
The first generation of On-Board
Diagnostics (called OBDI) 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.
Vehicle Coverage
This Scan Tool is designed to work with
all OBD II compliant vehicles, including
those equipped with a CAN bus.
OBD II was installed in some 1994 and
1995 model year gasoline vehicles.
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 are three examples:
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.
To verify if a 1994 or 1995 vehicle is OBD II
compliant, check the Vehicle Emissions
Control Information label, which is located in
the engine compartment.

• Communication Protocol: Allows
different systems and sensors in a

•Drive Cycle
A set of driving procedures that,
when met, provide the Enabling
Criteria for the I/M Monitors to run

•Enabling Criteria
Operating conditions that must
occur during a Drive Cycle to
cause the I/M Monitors to run and
complete their diagnostic tests.
•MIL: Malfunction Indicator Lamp
The vehicle’s “Check Engine”
warning light that activates
when a DTC is stored.
•DTC: Diagnostic Trouble Code A
code stored in the computer

identify the fault condition that is
causing the MIL to activate.
•Freeze Frame Data Operating

Control Modules to the Scan Tool.
Control Modules are individual computers that operate and monitor different systems in

ID codes are assigned to each Control Module, which are defined by the vehicle’s
Communication Protocol.
For example, a vehicle may use ID code $7E8 for the PCM and $7E9 for the TCM.
