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 established
guidelines that provide:
❒ A universal connector, called the DLC, with dedicated pin
assignments.
❒ 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 conditions 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
SAE has published hundreds of pages of text defining a standard
communication protocol that establishes hardware, software, and
circuit parameters of OBD II systems. Unfortunately, vehicle
manufacturers have different 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 computer
( about 10% of each manufacturers fleet ) were supposed 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.

Data Link Connector (DLC)
The data link connector (DLC) allows the Scan Tool to communicate
with the vehicle’s computer(s).
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 dashboard 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 dashboard in the area the DLC should have
been located. For more information on OBD II connectors, go to
http://www.obdclearinghouse.com/oemdb.

CodeConnect® is an experience-based database derived from over 4.7
million phone calls from technicians seeking assistance diagnosing
repair problems on their vehicles. CodeConnect® brings the
technology of professional technicians to a DIY scan tool. Don’t waste
time trying to find the answer. With the information CodeConnect®
offers, it takes vehicle repairs to the next level. Since you now know the
most probable fix for your problem, you can decide if you want to tackle
the repair yourself, or bring the vehicle to a local automotive repair
facility.
In order for CodeConnect® to work, you must select your
specific vehicle during vehicle selection. A Global OBD II

✓ Component Locator provides a vehicle specific location of
components found on the selected vehicle. It is a useful
companion function to CodeConnect®. CodeConnect® will
indicate components that repaired a problem associated with a
DTC, and Component Locator provides the location of the

specific component locations, a previous vehicle must be stored in
the Scan Tool.
✓ 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 vehicle is diagnosed.
✓ If an Error Message displays, make sure the OBDII 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 “Error Messages” in Troubleshooting.
✓ The Scan Tool keeps all data received from the last vehicle

The I/M Monitors (Inspection / Maintenance) function is used to view

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 DTC’s 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

✓ 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 conditions 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. See “Diagnostic Monitor Tests” in this section to see 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 catalysts.
❒ 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 downstream of catalyst has suffix x2. If
vehicle contains 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 Diagnostic Monitor Test function is useful after servicing or after
erasing a vehicle’s memory. Test results do not necessarily indicate a
faulty component or system.
✓ Non-CAN vehiclesDiagnostic Monitor Test receives test results for
emission-related powertrain components and systems that are not
continuously monitored.
✓ CAN vehicles Diagnostic Monitor Test receives test results for
emission-related powertrain components and systems that are and
are not continuously monitored.
✓ Vehicle manufacturer is responsible for assigning test and component
IDs.

Vehicle Information
The Vehicle Information function allows the Scan Tool to request the
vehicle’s VIN number, calibration ID(s) which identifies software version
in vehicle control module(s), calibration verification numbers (CVN(s))
and in-use performance tracking.
✓ Vehicle Information function applies to model year 2000 and newer
OBD II compliant vehicles.
✓ The Scan Tool cannot verify if data is correct for scanned vehicles.
✓ CVNs are calculated values required by OBD II regulations.
✓ The CVN calculation may take several minutes.
✓ CVNs are reported to determine if emission-related calibrations have
been changed. Multiple CVNs may be reported for a control module.
✓ In-use performance tracking, tracks performance of key I/M Monitors.
✓ Since CAN vehicles use module IDs larger than 2 digits, the Scan Tool
assigns a 2 digit module ID to be used in place of the actual CAN
module ID. The module ID assigned for the CAN module ID is used
in all functions of the Scan Tool.
❒ Verify ignition key is in the ON and not in the ACCESSORIES
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 broken 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 (dielectric) grease to the mating surfaces.
❒ With the key on engine off (KOEO), verify battery voltage is at
least 8.0V
❒ Verify the control module is not defective. Refer to the service
manual to diagnose the control module.
Scan Tool Does Not Power Up
✓ Review Safety Precautions before troubleshooting.
If Scan Tool will not power up, communic
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.
❒ Disconnect and reconnect DLC making sure it is connected
correctly.
❒ Check vehicle battery to make sure at least 8.0 volts is present.
❒ Contact customer service.
❒ With the engine off, check for blown fuses in the vehicle fuse box.
