About OBD II
OBD II stands for On-Board Diagnostics version II. OBD II is a system that the Society of
Automotive Engineers (SAE) developed to standardize automotive electronic diagnosis
to minimize vehicle pollution and to allow you to use the same tool to test any make and
model without special adapters. The SAE established guidelines that provide:
• a universal diagnostic test connector, called the data link connector (DLC), with
dedicated pin assignments.
• a standardized location for the DLC, visible under the dash on the driver’s side.
• a standardized list of Generic diagnostic trouble codes (DTCs) used by all
manufacturers. Certain DTCs are reserved for the manufacturer.
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 car makers 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 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, most of the new vehicles sold in the USA were fully OBD II compliant.
Diagnostic Trouble Code(s) (DTC)
Diagnostic Trouble Codes (DTCs) consist of a five-digit alphanumeric code in the format shown below. When the On-Board Computer recognizes and identifies a problem
in the computer-monitored systems, a DTC for that fault is stored in memory. These
codes are intended to help you determine the root cause of a problem. As new DTCs
are approved and added by the SAE, periodic updates to the software become available.

OBD II Diagnostic Link Connector (DLC)
The Data Link Connector (DLC) allows the scan tool to communicate with the vehicle
computer. OBD II defines the physical and electrical specification for the DLC. Certain
pins in the connector are reserved.
The DLC is also referred to as a J1962 connector, the term taken from a physical and
electrical specification number assigned by SAE (Society of Automotive Engineers). The
J1962 specification defines the location of
the DLC in the vehicle. The DLC should be
located under the dashboard on the driver
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.

What the Code Scanner Does
The Code Scanner connects to the vehicle and powers-up through the DLC. Once the
scanner establishes a communication link, you can then retrieve DTCs and erase data
stored in the vehicle. Code Lookup provides definitions of Global (Generic) OBD II DTCs.
Operating the Code Scanner
Control and Indicators
The scan tool is designed to be as intuitive as possible. All menu and lists operate the
same way.
• ENTER Key - selects displayed items and moves cursor in the Code Lookup
• YES/UP Arrow Key - responds yes to prompts, scrolls up and changes numbers
in Code Lookup.
• NO/DOWN Arrow Key - responds no to prompts, scrolls down and changes
numbers in Code Lookup.
• BACK Key - return to the previous screen or exit a function.
• LCD DISPLAY - A 2-line x 16-character display
with contrast adjust.
• OBD II (J1962) Adapter Cable - provides
power to the scanner and a link to the vehicle.
Code Scanner Functions
1. Connect the Code Scanner to the vehicle DLC, it
will not harm the vehicle.
2. The name and software ID displays momentarily.
3. Press ENTER to go to the Main Menu.
4. The display contrast can be adjusted for different
viewing angles. Select Display Contrast and use
the UP / DOWN arrow keys to increase and decrease the contrast. The setting will remain even
when the power is disconnected.
Avoid Cooling Fan! It May
Turn On During Test.
NOTE: If an Operating Error message is displayed, make sure the OBD II J1962
adapter cable is securely attached, and the ignition key is ON. Cycle the ignition key
to OFF for 10 seconds, then ON. This may be required to reset the PCM. Press the
BACK key to test again. If the problem still exists, refer to Troubleshooting Tips.
NOTE: Do not disconnect the Code Scanner until codes have been recorded. When
power is removed, Code Scanner memory is cleared.
Read Codes
The Read Codes function retrieves Diagnostic Trouble Codes (DTCs) from the vehicle’s
computer modules. This function can be performed with the Key On-Engine Off (KOEO)
or Key On-Engine Running (KOER). Because DTCs indicate a circuit or system failure
(not component failures) they are very useful in isolating vehicle system malfunctions.
There are two types of codes, Malfunction Indicator Lamp (MIL) codes and Pending
codes. An icon (;) will be displayed next to DTCs that are Pending codes.
MIL Codes: These codes cause the computer to illuminate the MIL when an emission related or driveability fault occurs. The MIL is also known as the “service engine
soon” or “check engine lamp”. The computer illuminates the MIL when the engine is
running and the DTC remains in memory until the fault is repaired.
Pending Codes: These codes are also referred as “continuous monitor” and “maturing codes”. An intermittent fault causes the computer to store a code in memory. If the
fault does not occur within 40 warm-up cycles, the code will be cleared from memory.
If the fault occurs a specific number of times, the code matures into a DTC and the
MIL turns on.
Turn the ignition key to the KOEO or KOER.
Select Read
Codes and press ENTER.
If there are no codes stored in vehicle memory, a “System
Pass” message displays.
If codes have been stored in vehicle memory, then the number of codes and type display (i.e. = 1 of 3 ;). Press the
DOWN arrow to view the codes. The definitions for Global
(Generic) DTCs display with the code number. Manufacturer-specific DTCs display the code number, and a message identifying the system
and to refer to a service manual.
Press the BACK key when done.
NOTE: Changing any part without first isolating the circuit or system may result in the
replacement of good components.
Erase Codes
The Erase Codes function deletes the DTCs from the vehicle’s memory. Perform this
function only after the systems have been checked completely and DTCs have been
documented. This function should be performed with KOEO - Do not START engine. An
error message will usually display when performing this function with KOER.
After servicing the vehicle, delete the stored DTCs and verify no codes have been reset.
If DTCs return, the problem has not been corrected or other faults are present.
The Erase function also erases freeze frame data, O2 sensor test data, system monitors, and on-board monitoring test results, which may be accessed by other Scan Tool
type equipment.
Select Erase Codes and press ENTER. Press YES to erase the codes or NO to retain the
codes. If NO is chosen, a “Erase Command Cancelled” message appears.
Once YES is selected, the function cannot be interrupted. Make sure to choose YES only
if codes are to be erased permanently. A message displays stating that “No Codes
Remain” or the number of DTCs that remain in memory.
If DTCs still exist, the number will be displayed. The faults must be repaired to remove
these DTCs. Press ENTER to return to the Main Menu. Press the BACK key when done.
MIL Status
The MIL (Malfunction Indicator Lamp) Status function displays the state of the computer
module that commanded the MIL to turn on. A request is sent to the computer module(s)
to state whether they are commanding the MIL to turn ON. If the MIL Status is ON and the
MIL is not illuminated with the engine running, then a problem exists in the MIL circuit.
Refer to “Diagnostic Circuit Check” in the service repair manual.
NOTE: Some manufacturers will turn the MIL Off if a certain number of drive cycles
occur without the same fault being detected. The DTCs related to a MIL are erased
from the computer’s memory after 40 warm-up cycles if the same fault is not detected.
Select the MIL Status function and press the ENTER key. The MIL Status displays on the
top line and a scrolling message on the bottom indicating if the MIL lamp should be ON
or OFF. When done, press the BACK key.
I/M Monitors
The I/M (Inspection and Maintenance) Monitors function displays the state of the vehicle’s
OBD II Monitors. Monitors test the operation of emission related systems or components and detect out-of-range values. The vehicle may have to be operated under certain driving conditions to initiate a monitor.
Currently, there are eleven OBD II Monitors defined and required by the U.S. Environmental Protection Agency (EPA), but not all monitors are supported by all vehicles.
Select I/M Monitors and press the ENTER key. Each I/M monitor and its status display
Using the Code Scanner®
per screen. Use the arrow keys to view them. When done, press the BACK key.
• A status of “Ready” means that the required driving conditions for that monitor have
been meet and it passed.
• A status of “Not Ready” means that the required driving conditions for that monitor
have not been met.
• A status of “Not Applicable (N/A)” means the vehicle does not support that monitor.
View Freeze Data
When an emission-related fault occurs, certain vehicle conditions are recorded by the
on-board computer. This information is referred to as a Freeze Frame data. The information is a “snapshot” of the operating conditions at the time of a fault. This data can be
overwritten by faults with a higher priority. If codes were erased, then freeze frame data
may not be stored in vehicle memory.
Select View Freeze Data and press ENTER. If freeze-frame data exists, then use the
arrow keys to view the DTCs and parameter identification data (PIDs).
If more than one computer module responds with freeze frame data, then the frame
number and module display on the first line. Press the ENTER key to change modules.
When done, press the BACK key.
Code Lookup
Code Lookup is a built-in OBD II Global (Generic) DTC database. It can be used to look
up the definitions of DTCs. The DTC database does not include manufacturer specific
DTC definitions.
Select Code Lookup and press ENTER. All characters must be entered – one character
can be changed at a time. The carat (^) symbol automatically displays under the first
Pressing the UP/DOWN arrow keys scrolls through the digits. Once the desired digit is
displayed, press the ENTER key and the ^ symbol moves under the next digit. Repeat for
the remaining digits in the code. After entering the last digit, the ENTER key displays the
definition. Once in the definition screen, press the UP/DOWN arrow keys to view the
previous or next code definition.
Press the ENTER or BACK key to return to the Code Lookup screen. Press BACK again
if done.
Troubleshooting Tips
Perform A Visual Inspection
Performing a thorough visual and “hands-on” underthe -hood inspection before starting any diagnostic procedure is essential. Many problems can be found this
way. Visually inspect for the following:
• Has the vehicle been serviced recently? Sometimes
things are reconnected in the wrong place, or not at
• Do not take shortcuts. Inspect hoses and wiring
which may be difficult to see because of location
(under air cleaner housing, alternators and similar
• Inspect the air cleaner and ductwork for defects.
• Check sensors and actuators for damage.
• Inspect all vacuum hoses for:
* Correct routing. Refer to vehicle service manual, or
Vehicle Emission Control Information (VECI) decal
located in the engine compartment.
* Pinches and kinks.
* Splits, cuts or breaks
• Inspect wiring for:
* Contact with sharp edges (a common problem).
* Contact with hot surfaces, such as exhaust
• Inspect Electrical Connectors for:
* Corrosion on pins
* Bent or damaged pins.
* Contacts not properly seated in housing.
* Bad wire crimps to terminals.
* Problems with connectors are common in the engine
control system. Inspect carefully.
NOTE: Some connectors use a special grease on the contacts to prevent corrosion. Do
not remove. If required, apply more grease to the connector (available from vehicle
Code Scanner Does Not Power Up
• Make sure the DLC is properly connected to the vehicle connector. Verify pins are
clean and fully seated in connector.
• The Code Scanner requires a minimum of 8 volts between pin 16 (12V) and pin 4
(Gnd) to power up. Use the flowchart to troubleshoot.

Link Errors or Erroneous Data
If the Code Scanner displays link errors when attempting to
read, erase, or look up codes, check the following:
• Make sure the cable is securely connected to the DLC.
• Verify ignition key is ON and not in the ACCESSORIES
• Examine the DLC closely and check for cracked or recessed pins, or for any substance that could prevent a good electrical connection.
• Verify that the vehicle you are testing is an OBD II compliant vehicle. Just because it
has the OBD II J1962 DLC does not mean the vehicle is OBD II compliant.
• Test for continuity between the DLC wiring and the PCM. In an extreme case there
may be a broken wire.
• Check the vehicle for blown fuses. If the PCM fuse is blown, it cannot transmit data.
NOTE: The PCM fuse may be located on the fuse block in the passenger compartment.
• Make sure the PCM has a good ground. If the PCM has a ground directly to the case,
clean the connection and apply a conductive grease to the mating surfaces.
• As a last resort, the PCM may be defective. Refer to the vehicle service manual for
correct procedures for testing the PCM.
If the Code Scanner is not working correctly after the checks and corrections above,
contact the technical support line at 1-800-228-7667 (8:00 - 6:00 EST Monday - Friday),
or visit our web site at www.actron.com.

All parameter identification data (PID) listed was verified on actual vehicles to guarantee accuracy. Definitions used to describe all PIDs were obtained from reliable
sources and are accurate at time of printing. It is possible that some newer vehicles
may contain data different from that listed in Appendix A. Always refer to vehicle service
manual for manufacturer specific PIDs.
Data Parameter List Format
The PID list is organized in alphabetical order — the same way the scan tool does.
For each PID, the type of reading are provided. Remember to always refer to a vehicle
service manual for detailed diagnostic procedures for troubleshooting incorrect PID
Types of Data Parameters
INPUT: These data parameters are obtained from sensor circuit outputs.
Sensor circuit outputs are inputs to vehicle’s PCM. For example, if
Oxygen Sensor circuit was generating a 400mV signal, then scan
tool would read O2S (v) 0.40.
OUTPUT: These data parameters are outputs or commands that come directly
from computer module(s). For example; the ignition spark advance
is controlled by PCM, on most vehicles, monitoring this PID shows
spark output from PCM. The scan tool would display IGN ADV(°) 10.
CALCULATED: These data parameters are calculated after analyzing various inputs
to the vehicle’s computer module(s). For example, the engine load.
The PCM calculates this from sensor inputs and displays it in a
