1. Safety Precautions and Warnings
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:
Do not attempt to operate or observe the tool while driving a vehicle.
Operating or observing the tool will cause driver distraction and
could cause a fatal accident.
Wear safety eye protection that meets ANSI standards.
Operate the vehicle in a well ventilated work area: Exhaust gases
are Poisonous.
Put the transmission in PARK (for automatic transmission) or
NEUTRAL (for manual transmission) and make sure the parking
brake is engaged.
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.
Always perform automotive testing in a safe environment
The first generation of On-Board Diagnostics (called OBD I) was developed by
the California Air Resources Board (CARB) 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 “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:
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 other four
characters, all numbers, provide additional information on where the DTC
originated and the operating conditions that caused it to be set. Below is an
example to illustrate the structure of the digits:

The DLC (Data Link Connector or Diagnostic Link Connector) is the
standardized 16-cavity connector where diagnostic scan tools 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 the Data Link Connector is not located under the dashboard, a label
should be there revealing its 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.
Figure 1-3: The DLC connector (left) can be found in the
area of the car interior seen at right (black arrow).

2.4 OBD II Definitions
PowertrainControl Module (PCM) - the OBD II terminology for the on-board
computer that controls the engine and the drive train.
Malfunction Indicator Light (MIL)- Malfunction Indicator Light (Service Engine
Soon, Check Engine) is a term used for the light on the instrument panel. It 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 can not turn the MIL off until necessary
repairs are completed or the condition no longer exists.
DiagnosticTrouble Codes (DTC) – These identify which section of the
emission control system has malfunctioned.
Freeze Frame Data – When an emissions related fault occurs, the OBD II
system not only sets a code, but also records a snapshot of the vehicle
operating parameters to help in identifying the problem. This set of values
operating parameters to help in identifying the problem. This set of values is
referred to as Freeze Frame Date and may include important engine is referred
to as Freeze Frame Date and may include important engine parameters such as
engine RPM, vehicle speed, air flow, engine load, fuel pressure, fuel trim value,
engine coolant temperature, ignition timing advance, or closed loop status.

6. FAQ
1. What kind of car is supported?
The PlusQuip EQP-120 supports cars with 12v, 16 pin interface,
OBDII compliant vehicles from the USA, Euope and Asia since 1996.
2. The PlusQuip EQP-120 is connected to the vehicle
but the data cannot be read?
After plugging the EQP-120 into the vehicle’s OBDII interface, turn the
key to the ON position, or start the engine to test again. (Without this, the
screen will illuminate but data cannot be read.)
3. The Fault Codes were erased but the warning light
remains illuminated?
Fault Codes are divided into Temporary Fault Codes and Permanent Fault
Codes. If the fault is Temporary, the EQP-120 will remove it. If the fault is
Permanent, even though the Fault Code is erased, the warning light will
remain illuminated. This indicates the issue with the vehicle has not been
resolved. The vehicle will have to be repaired by a professional mechanic.
