CAUTION

Laser 5091 Code Reader User’s Guide Laser 5091 Code Reader User’s Guide
And always use your code reader as described in the user’s manual, and follow
all safety messages.
Do not route the test cable in a manner that would interfere with
driving controls.
Do not exceed voltage limits between inputs specified in this user’s
manual.
Always wear ANSI approved goggles to protect your eyes from
propelled objects as well as hot or caustic liquids.
Fuel, oil vapors, hot steam, hot toxic exhaust gases, acid, refrigerant
and other debris produced by a malfunction engine can cause serious injury or
death. Do not use code reader in areas where explosive vapor may collect, such
as in below-ground pits, confined areas, or areas that are less than 18 inches (45
cm) above the floor.
Do not smoke, strike a match, or cause a spark near the vehicle
while testing and keep all sparks, heated items and open flames away from the
battery and fuel / fuel vapors as they are highly flammable.
Keep a dry chemical fire extinguisher suitable for gasoline, chemical
and electrical fires in work area.
Always be aware of rotating parts that move at high speed when an
engine is running and keep a safe distance from these parts as well as other
potentially moving objects to avoid serious injury.
Do not touch engine components that get very hot when an engine
is running to avoid severe burns.
Block drive wheels before testing with engine running. Put the
transmission in park (for automatic transmission) or neutral (for manual
transmission). And never leave a running engine unattended.
Do not wear jewelry or loose fitting clothing when working on
engine.
Make sure to turn off ignition before connecting or disconnecting
the code reader.

What is OBD?
The first generation of On-Board Diagnostics or OBD I was introduced in early
1980’s to control engine functions and diagnose engine problems by vehicle
manufacturers. As the OBDI lacked standardization of protocols and interface, it
allowed different interpretations among vehicle manufacturers.
OBDII, the second generation On-Board Diagnostics, improved in both
capability and standardization, is a system developed in mid 1990’s by the
Society Automotive Engineers (SAE) to standardize automotive electronic
diagnosis. EOBD is European version of OBDII required in Europe since 2001.
The OBDII standard specifies:
• A generic diagnostic port (Data Link Connector) and its pinout;
• The protocols and the messaging format;
• A standard list of vehicle parameters identifications;
• A standard list of diagnostic trouble codes (DTCs);

Data Link Connector
The Data Link Connector (DLC) is a standard 16-pin interface located under the
dashboard on the driver’s side of the passenger compartment. If the DLC is not
located under the dashboard as stated, a decal describing its location should be
attached to the dashboard in the area where the DLC should have been located.
On some Asian and European vehicles the DLC is located behind the
“ashtray”, which must be removed to access it, or on the far left corner of the
dash. If the DLC cannot be found, consultthe vehicle’s service manual for the
location.
Diagnostic Trouble Codes (DTCs)
Diagnostic Trouble Codes (DTCs) are faults stored by vehicle computers when
problems that affect engine performance and emissions are detected. DTCs are
used to help identify the cause of a trouble or troubles with a vehicle, and
determine the fault location(s).
DTCs consist of a five-digit alphanumeric code. Please see below for the DTCs
format and code types.
