3.3 Introduction to On-Board Diagnostics
SAE J1587/J1708
SAE J1587 is a diagnostic protocol standard developed
by the Society of Automotive Engineers (SAE) for heavy-
duty and most medium-duty vehicles built after 1985. Up
to 1995, individual OEMs used their own connectors.
From 1996 to 2001, the 6-pin Deutsch was standard.
Beginning in 2001, most OEMs converted to the 9-pin
Deutsch. Some OEMs still use the 6-pin Deutsch.
SAE J1708 is an SAE physical specification developed
for heavy duty vehi cles (trucks and busses). The proto-
col promoted a standard for serial communication
between modules with microcontrollers. J1708
describes the physical and data link layer. Almost always
used in conjunction with the application layer protocol
SAE J1587.
SAE J1939
In the early 90’s, the SAE Truck and Bus Control and
Communications Sub-committee started the develop-
ment of a CAN-based application pro file for in-vehicle
communication in trucks. In 1998, the SAE published the
J1939 set of specifications. A J1939 network connects
electronic control units (ECU) within a truck and trailer
system. The J1939 specification - with its engine, trans-
mission, and brake message definitions - is dedicated to
diesel engine applications.
SAE J1939 has been adopted widely by diesel engine
manufacturers. One driving force behind this is the
increasing adoption of the engine Elec tronic Control
Unit (ECU), which provides one method of controlling
exhaust gas emissions within US and European stan-
dards. Consequently, SAE J1939 can now be found in a
range of diesel-powered applications: vehicles (on- and
off-road), marine propulsion, power generation, and
industrial pumping.
OBD II
On-Board Diagnostics version II (OBD II) is a system that
the Society of Automotive Engineers (SAE) developed to
standardize automotive electronic diagnosis.
Beginning in 1996, most new vehicles sold in the United
States were fully OBD II compliant.
Technicians can now use the same tool to test any OBD
II compliant vehicle without special adapters. SAE estab-
lished guidelines that provide:
• A universal OBD II data link connector, called the
DLC, with dedicated pin assignments.
• Diagnostics with vehicle modules involved in emis-
sions controls such as ECM/PCM & transmission.
• A standard location for the DLC, visible under the
dash on driver’s side.
• A standard list of diagnostic trouble codes (DTCs)
used by all manufacturers.
• A standard list of parameter identification (PID) data
used by all manufacturers.

• Ability for vehicle systems to record operating condi-
tions when a fault occurs.
• Expanded diagnostic capabilities that records a
code whenever a condition occurs that affects
vehicle emissions.
• Ability to clear stored codes from the vehicle’s
memory with a scan tool.
3.4 SAE Publications
SAE has published hundreds of pages of text defining a
standard communication protocol that establishes hard-
ware, software, and circuit parameters of OBD II sys-
tems. Unfortunately, vehicle manufacturers have differ-
ent interpretations of this standard communications
protocol. As a result, the generic OBD II communications
scheme varies, depending on the vehicle. SAE publishes
recommendations, not laws, but the Environmental
Protection Agency (EPA) and California Air Resources
Board (CARB) made many of SAE’s recommendations
legal requirements that vehicle manufacturers were
required to phase in over a three-year period. Beginning
in 1994, vehicles with a new engine management com-
puter (about 10% of each manufacturers fleet) were sup-
posed to comply with OBD II standards. For 1995, OBD
II systems were to appear on about 40% of the new
vehicles sold in the United States. 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, most of
the new vehicles sold in the United States were fully
OBD II compliant.
3.5 Data Link Connector (DLC)
The data link connector (DLC) allows the scan tool to
communicate with the vehicle’s computer(s). Use the
proper DLC adapter cable to connect the scan tool to
the vehicle. Also, the vehicle’s DLC may be found in
several different places and have many different configu-
rations.
IMPORTANT
Power to the tool generally comes from
the vehicle. If the tool does not power-up,
use the included cigarette lighter cable
(7-0135) to power-up the tool.
J1939 Type 2
The J1939 Type 2 is a round 9-pin green DLC adapter
cable (HDS 200: 1699200242) (HDS 250: 1699200245).
This cable will work on trucks with older J1939 Type 1
and new J1939 Type 2 DLCs.
The vehicle DLC is generally mounted inside the cab.
For on road heavy trucks, the connector should be
mounted on the driver side. For busses, the vehicle DLC
should be mounted within reach of the operators seat.
Attach the 9-pin green adapter cable to the extender
cable (7-0137) (both supplied with the scan tool) to con-
nect the tool.
J1708/J1587
The J1708/J1587 connector is a round 6-pin gray DLC
adapter cable (HDS 200: 1699200241) (HDS 250:
1699200244).
Attach the 6-pin grey adapter cable to the extender cable
(7-0137) (both supplied with the scan tool) to connect
the tool.
OBD II (J1962)
Beginning in 1996, vehicles sold in the United States use
the J1962 (OBD II) DLC, a term taken from a physical
and electrical specification number assigned by the SAE
(J1962). The DLC should be located under the dash-
board on the driver’s side of the vehicle. If the DLC is
not located under the dashboard as stated, a decal
describing its location should be attached to the dash-
board in the area the DLC should have been located. For
more information on OBD II connectors, go to
http://www.obdclearinghouse.com.
Because the OBD II J1962 connector has power and
ground, you only need a single cable connection to the
tool for both power and vehicle communications. Attach
the OBD II adapter cable (HDS 200: 1699200243) (HDS
250: 1699200246) to the extender cable (7-0137) (both
supplied with the scan tool), to
connect the tool. Certain pins in the connector are
reserved.

3.6 J1939 Diagnostic Trouble Codes
J1939 DTCs are made up of a Suspect Parameter Num-
ber (SPN) and the Failure Mode Identifier (FMI). The
SPN identifies the failed component or system. The FMI
identifies the type of failure.
J1939 defines a standard set of DTCs. SAE reserves
SPNs 0 to 516095. SPNs 516096 to 524287 are
reserved for the manufacturer.
3.7 J1587 Diagnostic Trouble Codes
J1587 DTCs are made up of either a Parameter Identifi-
cation number (PID) or a Subsystem Identification
number (SID). It is also made up of a Failure Mode
Identifier (FMI). The SID or PID identifies the failed
component or system. The FMI identifies the type of
failure.
3.8 OBD II Diagnostic Trouble Codes
(DTCs)
J2012 and ISO 15031-6 are standards for all DTCs,
established by the SAE, International Organization for
Standardization (ISO) and other governing bodies.
• Codes and definitions assigned by these specifica-
tions are known as Generic OBD II codes.
• OBD II requires compliance to these standards for
all cars, light trucks, APVs, MPVs, and SUVs sold in
the United States.
• Codes not reserved by the SAE are reserved for the
manufacturer and referred to as Manufacturer Spe-
cific Codes.
DTCs are used to help determine the cause of a problem
or problems with a vehicle.
• DTCs consist of a five-digit alphanumeric code.
• The DTCs format and general code types are shown
below.
1. Bx = Body
Cx = Chassis
Px = Powertrain
Ux = Network communication

6 OBD II Diagnostics
OBDII Diagnostics is available by selecting HD OBD (ISO
15765-4) or Global Automotive OBDII from the Main
Menu.
This section applies to all Global OBD II compliant vehi-
cles. The first time the scan tool links to the vehicle, the
communication protocol is automatically detected, and
is used until the scan tool is turned off or another vehi-
cle is diagnosed.
If an error message displays, make sure the OBD II
connector is attached and the ignition key is on. Cycle
ignition key to OFF for 10 seconds, then ON. This may be
required to reset computer. If required, select YES to try
again. If problem still exists, refer to “7.1 Error Mes-
sages” on page 41.
The scan tool keeps data received from the previous
vehicle selected until any of the following occurs:
• A new vehicle is selected.
• Scan tool is flash programmed to update software.
On initial link to vehicle, scan tool checks the status of
I/M Monitors no matter which function is selected.
IMPORTANT
Review Data, Print Data, and System
Setup are covered in Section 5 of this

6.1 I/M Monitors (Emissions)
The I/M Monitors (Inspection / Maintenance) function is
used to view a snapshot of the operations for the emis-
sion system on OBD II vehicles. I/M Monitors is a very
useful function. To guarantee no faults exist make sure
all monitors are ok or n/a and no DTCs exist. Refer to the
vehicles service manual for the drive cycle operation.
During normal driving conditions, the vehicle computer
scans the emission system. After a specific amount of
drive time (each monitor has specific driving conditions
and time required), the computer monitors decide if the
vehicles emission system is working correctly or not as
well as detecting out of range values. When the monitor
status is:
• ok - vehicle was driven enough to complete the
monitor.
• inc (Incomplete) - vehicle was not driven enough to
complete the monitor.
• n/a (not applicable)- vehicle does not support that
monitor.
Depending on vehicle, disconnecting or a discharged
battery may erase DTCs and clear monitor status. Moni-
tors may be reset by:
• Erasing codes
• Vehicle control modules losing power
The I/M Monitors function can be run key on engine
running (KOER) or key on engine off (KOEO).
Extreme weather and/or road conditions can prevent a
monitor from running. Also, some monitors may require
a cold start to complete.

6.2 Read Codes
The Read Codes function allows the scan tool to read
the DTCs from the vehicle’s control modules. DTCs are
used to help determine the cause of a problem or prob-
lems with a vehicle. These codes cause the control
module to illuminate the malfunction indicator lamp
(MIL) when emission-related or driveability fault occurs.
When referring to the engine control module, MIL is also
known as service engine soon or check engine lamp.
Read Codes can be done with the key on engine off
(KOEO) or with the key on engine running (KOER).

DTC Number - number of the trouble code found in
vehicle service information.
X of Y - Indication that code x of y is being viewed,
where x is the code being viewed of the total y.
Module - The address of the module (e.g. Mod $28) is
shown in this field. The table below describes modules
supported.

DTC Description - This area is reserved for the text
describing the trouble code listed in the DTC number
field.
DTC Type - This area is reserved for providing additional
information about the DTC. Multiple DTC types may be
possible for a given DTC number. Not all vehicles sup-
port DTC types.
This table describes possible DTC types.
DTC Type Description
Confirmed
Confirmed codes are reported when a
component, sensor, or other part of the
vehicle is indication a malfunction is pres-
ent.
Current
Codes transmitted through the PCMs da-
ta stream when a trouble condition is ac-
tive and cannot be erased. The problem
must be repaired to remove the DTC.
Pending
Pending codes are also referred to as
continuous monitor or maturing codes.
An intermittent fault causes the control
module to store a code in memory. If the
fault does not occur within a certain num-
ber of warm-up cycles (depending on ve-
hicle), the code clears from memory. If
fault occurs a specific number of times,
the code matures into a DTC and the MIL
illuminates or blinks. This function can be
used with KOEO or KOER.
Examples of Read Codes information screens follow.
In this example, module (MOD) $18 is reporting the
DTCs.

Perform Erase Codes function only after systems have been
checked completely and DTCs have been written down.
After servicing the vehicle, erase stored DTCs and verify
no codes have returned. If a DTC returns, problem has
not been fixed or other faults are present.
Permanent DTCs cannot be erased with the Erase Codes
function.
Depending on which monitor sets a code, the vehicle
may need to be driven and the monitor ran before con-
cluding that the fault is repaired.

6.9 Drive Cycle Monitor
The Drive Cycle Monitor function is very similar to I/M
Monitors though the Drive Cycle Monitor is used to
view real-time operations of the emissions system on
OBD II vehicles. Drive Cycle Monitor continuously
updates as the vehicle reports operations of the emis-
sion system.
CAUTION
Two people must be in vehicle when driv-
ing. One to drive and the other to operate
the scan tool.
• Refer to the vehicle service manual for the drive
cycle operation.
Drive Cycle Monitor can be used if you want to drive the
vehicle until all of the monitors are OK.
During normal driving conditions, the vehicle computer
scans the emission system. After a specific amount of
drive time (each monitor has specific driving conditions
and time requirements), the computer monitors will
decide if the vehicle emissions system is working cor-
rectly or not as well as detecting out a range of values.
When the monitor status is:
• “ok” - vehicle has been driven enough for function.
• “inc” (incomplete) - vehicle was not driven enough
to complete all of the monitors.
• “n/a” (not applicable) - vehicle does not support
that monitor.
Reset monitors by:
• Erasing codes.
• Vehicle computer module losing power (on some
vehicles).

6.10 O2 Monitor Tests
OBD II regulations require applicable vehicles monitor
and test oxygen (O2) sensors to determine problems
related to fuel and emissions. The O2 Monitor Tests
allows retrieval of completed O2 sensors monitor test
results.
• The O2 Monitor Tests is not an on-demand test. O2
sensors are not tested when selected via the menu.
O2 sensors are tested when engine operating condi-
tions are within specified limits.
• If the vehicle communicates using a controller area
network (CAN), O2 Monitor Tests are not supported
by vehicle. A message is displayed. Refer to “6.11
Diagnostic Monitor Tests” on page 37 for O2
monitor data.
• O2 sensors are located before (upstream) and after
(downstream) catalyst(s). Sensors are named (xy)
for their position to both cylinder banks and cata-
lysts.
– The O2 sensor for cylinder bank 1 has prefix 1y
while O2 sensor for cylinder bank 2 has prefix
2y.
– The O2 sensor upstream of catalyst (closest to
engine) has suffix x1 while O2 sensor down-
stream of catalyst has suffix x2. If vehicle con-
tains more catalysts, O2 sensor downstream of
second catalyst has suffix x3 and O2 sensor
downstream of next catalyst has suffix x4.
– For example, O2S21 is upstream O2 sensor for
cylinder bank 2.
The following O2 Sensor Tests are available:
• Rich-to-lean sensor threshold voltage
• Lean-to-rich sensor threshold voltage

7 Troubleshooting
7.1 Error Messages
Check the following if an error message displays:
• Verify ignition key is in the ON and not in the ACCES-
SORIES position.
• Make sure the DLC Cable is attached to vehicle’s
data link connector (DLC) and scan tool.
• Look at DLC and check for cracked or recessed pins,
or for any substance that could prevent a good
electrical connection.
• Test for continuity between the DLC wiring and the
computer. In an extreme case, there may be a bro-
ken wire.
• Check for bent or broken pins.
• With the engine off, check for blown fuses in the
vehicle fuse box.
• Make sure the vehicle’s control module has a good
ground. If the computer case is grounded, then
clean the connection and apply a conductive (dielec-
tric) grease to the mating surfaces.
• With the key on engine off (KOEO), verify vehicle
battery voltage is at least 8.0V.
• Verify the control module is not defective. Refer to
the service manual to diagnose the control module.
7.2 Scan Tool Does Not Power Up
WARNING
Review Safety Messages on page 4
before troubleshooting.
If scan tool will not power up, communicate with vehicle
control module, pass scan tool self-tests, or functions
incorrectly in any other way, do the following:
• Check and replace the batteries if needed.
• Clean the DLC pins.

7.5 Battery Replacement
The scan tool requires 4-AAA alkaline batteries to oper-
ate without vehicle power.
• When the batteries need to be replaced, the low-
battery icon ( ) is displayed.
• Rechargeable batteries do not last as long as alka-
line types and are not recommended.
• Non-rechargeable Lithium (Li) battery can be used.
Lithium types last longer than the alkaline types, but
they are more expensive.
1. Place display face-down on a non-abrasive surface.
2. Remove battery cover by turning phillips screw
counterclockwise. Slide battery cover off.
3. Remove batteries and properly discard.
4. Install four new AAA Alkaline batteries.
5. Reinstall battery cover by sliding battery cover on.
Install phillips screw turning it clockwise. Do not
overtighten screw.
7.6 Tool Self-Tests
Tool Self-Tests check the display, keys, and internal
memory.
• Refer to “4 Using the Scan Tool” on page 10 for
the operation procedures for scan tool self-tests.

A/C:
Air conditioner
A/C clutch relay:
The PCM uses this relay to energize the A/C clutch,
turning the A/C compressor on or off.
A/C pressure sensor:
Measures air conditioning refrigerant pressure and
sends a voltage signal to the PCM.
A/C pressure switch:
A mechanical switch connected to the A/C refrigerant
line. The switch is activated (sending a signal to the
PCM) when the A/C refrigerant pressure becomes too
low or high.
A/D:
Analog to digital
A/F:
Air/Fuel ratio. The proportion of air and fuel delivered to
the cylinder for combustion. For example, an A/F ratio of
14:1 denotes 14 times as much air as fuel in the mixture.
Ideally the A/F ratio is 14.7:1.
ABS:
Anti-lock crake system
Accel:
Accelerator
Acssry:
Accessory
Actuator:
Actuators such as relays, solenoids, and motors allow
the PCM to control the operation of vehicle systems.
Air Injection Reaction (AIR) System:
An emission control system operated by the PCM. Dur-
ing cold starts, an air pump injects outside air into the
exhaust manifold to help burn hot exhaust gases. This
reduces pollution and speeds warm-up of oxygen sen-
sors and catalytic converters. After the engine is warm,
the air will either be dumped back to the atmosphere (or
into the air cleaner assembly) or sent to the catalytic
converter.
