The original on-board diagnostics (OBD I) lacked consistency in communication and interfac e while allowin g different interpr etations am ongst vehicle m anufacturers. For d and Chr ysler used different types of engine cont rol comput ers
and data link conn ectors, and GM varied the tr ouble codes and communicat ion
protocols from year-to-year.
The tables belo w highl ight changes for GM, Ford, and Chrysl er. If this seems
confusing; d on’t worry. Your tool makes it easy. Based on the VI N information
selected during Scan Tool setup, the processor is aut omatically recogni zed. All
you have to do is choose the correct adapter cable and jumper wires (if necessary). Details on adapter cables and jumper wires may be found in “Diag-

OBD II stands for O n-Boar d Diagnos tics ver sion I I. OBD I I is a syste m tha t the
Society of Autom otive Engineers (SAE) dev eloped to standardize automotive
electronic diagnosis. Technicians now can use the same tool to test any OBD
II compliant vehic les without special adapt ers. The SAE establish ed guidelines
that provide:
• a universal diagnostic test connector, c alled the data link connector (DLC),
with dedicated pin assi gnm ents.
• a standardized location for the DLC, visible under the dash on the driver’s
side.
• a standa rdi zed list of diagnostic trouble codes (DTCs) used by all manufacturers.
• a standardized list of parameter identification (PID) data used by all manufacturers.
• the ability of the vehicle system to recor d a freeze frame of the operati ng conditions when a fault occurs.
• expanded diagnostic capabilities that records a code whenever a condition
occurs that ef fects vehicle emissions.
• the ability to clear stored codes from vehicle memory with the scan tool.
In addition, SAE has published hundreds of pages of text defining a stan dard
communications protocol that establishes the hardware, software, and cir cuit
parameters of OBD II systems. Unfortunately , vehicle manufacturers have different interpr etations of this standard comm unications prot ocol. As a result, the
generic OBD II communic ations scheme us ed will vary, depending on t he vehicle.
SAE publishes r ecom m endations, not laws, bu t t he Environmental Protection
Agency (EPA) and California Air Resources Board (CARB) made many of
SAE’s recommenda ti ons legal requirements that vehicle manufacturers were
required to phase in over a three-year period. Beginni ng in 1994, vehicle s with
a new engine m anagement c omputer – about 1 0% of ea ch manufact urers fl eet
– were supposed to comply with O BD II standards. For 1995, OBD II systems
were to appear on about 40% of t he new vehic les sold in t he USA. Some of the
1994-1995 OBD II systems were not fully compliant, so the Government
granted waivers to give manufacturers time to fine-tune their systems. Beginning in 1996, m ost of the new vehicles sold in the USA were fully OBD II compliant.

DIAGNOSTIC LINK CONNECTORS (DLC)
The Data Link Connector (DLC) allows the scan to ol to communicate wit h the
vehicle’ s com puter(s). Before OBD II, manufactur ers used different data link
connectors to communicate with the vehicle. The proper DLC adapter cable
must be used to connect the tool to the ve hicle. Also , the vehi cle’s DLC may be
found in several different places and have many different configurations. The
following descri bes the DLCs used by Ford, GM and Chrysl er. The DLC lo cation
and types for domestic vehicles can be looked up in the charts in “Appendix
A - Data Link Connectors".
OBD II (J1962)
Beginning in 1996, vehicl es sold in
the United States use the J1962
(OBD II) DLC, a term taken from a
physical and el ectrical speci fication
number assigned by SAE (J1962).
The DLC should be located under
the dashboard o n t he dri ver si de of the vehicl e. I f the DLC is n ot locat ed under
the dashboard as stated, a decal describing its location should be attached to
the dashboard in the area the DLC should have been located.
Because the OBD II J196 2 conn ector ha s power and ground , yo u only need a
single cable conn ection to the tool for both power and tool communi cations.
Attach the OBD II adapter cable to the extender cabl e, both supplied with the
tool, to connect the t ool. Certain pins in the connector are reserved.

The pigtail connector is not used on MCU vehicles – leave the pigtail unattached. The EEC-IV/MCU cable adapter is included with the scan tool.
MECS vehicles (1988 –1995) use either a 6-pin (with pigtail) or a 17-pin DLC.
Use the MECS 6-pin adapte r cable k it (P/N 9603) fo r both con figur ation s. The
MECS adapter cable ki t includes jumpe r wires to connect to the MECS 17- pin
DLC. The MECS adapter cable kit is not included with this tool. It is available
through your dealer. Us e the following diagram s to connect the adapter cable.
Certain Ford Probes have a WHITE TACH CONNECTOR
located very close to the 6-pi n Self-Test connec tor and
bundled in the same wiring harness. This is NOT the STI
(Self Test Input) Pigtail.
Connect the pigtail to the BLACK STI connector located fart her back on the wire
harness. If the tool is connec ted to the WHITE Tach co nnector , serious damage
will result and may void warranty. Refer to the illustration.

Printer Interface
The scan tool is designed as a Data Terminal Equipment (DTE) dev ice with a
DB9M (9-pin D-shape male) connector to interface with a compatibl e serial
printer.
Compatible Printers
The printer must have a ser ial RS- 232 inte rface c ircui t and be comp at ible wit h
the Epson FX format. The following printers are recommended:
❒ Seiko DPU-414
❒ Kodak DICONIX 180si (seri al printer model)
❒ Lexmark Model 2480 with optional serial interface (p/n 12T0154)
❒ Panasonic KX-P1131 printer
Cabling
❒ Type: A standard RS-232 type cable.
❒ Scan Tool end: DB9F (female) connector.
❒ Printer end:
• Use a DB9M (male) connec-t or for the Seiko and
Kodak printers.
• Use a DB25 male connector f or the Lexmark and
Panasonic printers.
• If the printer uses a di fferent connector, then an
adapter or different RS-232 cable is required.
Adapters are available at most local PC stores or
electronics outlets.
Serial Port Settings
❒ Default settings for the scan tool are: 9600 Baud, 8 Data Bits, No Parity
and 1 Stop Bit.
❒ Ensure the settings on the scan tool and printer match .
