Introduction
WHAT IS OBD?
WHAT IS OBD?
The Enhanced CanOBD2&1 Scan Tool is designed to work on most
Chrysler, Ford, GM and Toyota OBD1 systems and all OBD2
One of the most exciting improvements in the automobile industry was the addition of on­board diagnostics (OBD) on vehicles, or in more basic terms, the computer that activates the vehicle’s “CHECK ENGINE” light. OBD1 was designed to monitor manufacturer-specific systems on vehicles built from 1981 to 1995. Then came the development of OBD2, which is on all 1996 cars and light trucks sold in the United States. These systems are part of a government mandate to lower vehicle emissions. The sophisticated programs in the vehicle’s on-board computer system are designed to detect failures in a range of vehicle systems. Diagnostic information can be accessed through a Data Link Connector test port specifically designed for this purpose. For all OBD systems, if a problem is found, the computer turns on the “CHECK ENGINE” light to warn the driver, and sets a Diagnostic Trouble Code (DTC) to identify where the problem occurred. A special diagnostic tool, such as the Enhanced CanOBD2&1 Scan Tool, is required to retrieve these codes, which consumers and professionals use as a starting point for repairs.
The Enhanced CanOBD2&1 Scan Tool provides the additional ability to retrieve enhanced DTCs from most Chrysler/Jeep, General Motors, Ford, Mazda and Isuzu vehicles. The types of enhanced data available depends on the vehicle make.
compliant vehicles.

Safety Precautions
SAFETY FIRST!
SAFETY FIRST!
To avoid personal injury, instrument damage and/or damage
to your vehicle; do not use the CanOBD2&1 Scan Tool
This manual describes common test procedures used by experienced service technicians. Many test procedures require precautions to avoid accidents that can result in personal injury, and/or damage to your vehicle or test equipment. Always read your vehicle's service manual and follow its safety precautions before and during any test or service procedure. ALWAYS observe the following general safety precautions:
When an engine is running, it produces carbon monoxide, a toxic and poisonous gas. To prevent serious injury or death from carbon monoxide poisoning, operate the vehicle ONLY in a well-ventilated area.
To protect your eyes from propelled objects as well as hot or caustic liquids, always wear approved safety eye protection.
before reading this manual.
When an engine is running, many parts (such as the coolant fan, pulleys, fan belt etc.) turn at high speed. To avoid serious injury, always be aware of moving parts. Keep a safe distance from these parts as well as other potentially moving objects.
Engine parts become very hot when the engine is running. To prevent severe burns, avoid contact with hot engine parts.
Before starting an engine for testing or troubleshooting,
N
R
P
make sure the parking brake is engaged. Put the
D
L
transmission in park (for automatic transmission) or neutral (for manual transmission). Block the drive wheels
with suitable blocks.
Connecting or disconnecting test equipment when the ignition is ON can damage test equipment and the vehicle's electronic components. Turn the ignition OFF before connecting the CanODB2&1 Scan Tool to or disconnecting the CanODB2&1 Scan Tool from the vehicle’s Data Link Connector (DLC).

Safety Precautions
SAFETY FIRST!
To prevent damage to the on-board computer when taking vehicle electrical measurements, always use a digital multimeter with at least 10 megOhms of impedance.
Fuel and battery vapors are highly flammable. To prevent an explosion, keep all sparks, heated items and open flames away from the battery and fuel / fuel vapors. DO NOT SMOKE NEAR THE VEHICLE DURING TESTING.
Don't wear loose clothing or jewelry when working on an engine. Loose clothing can become caught in the fan, pulleys, belts, etc. Jewelry is highly conductive, and can cause a severe burn if it makes contact between a power source and ground.

Preparation for Testing
BEFORE YOU BEGIN
BEFORE YOU BEGIN
The Enhanced CanOBD2&1 Scan Tool aids in monitoring electronic­and emissions-related faults in your vehicle and retrieving fault codes related to malfunctions in these systems. Mechanical prob­lems such as low oil level or damaged hoses, wiring or electrical connectors can cause poor engine performance and may also cause a fault code to set. Fix any known mechanical problems before performing any test. See your vehicle’s service manual or a mechanic for more information.
Check the following areas before starting any test:
Check the engine oil, power steering fluid, transmission fluid (if
applicable), engine coolant and other fluids for proper levels. Top off low fluid levels if needed.
Make sure the air filter is clean and in good condition. Make sure all
air filter ducts are properly connected. Check the air filter ducts for holes, rips or cracks.
Make sure all engine belts are in good condition. Check for cracked,
torn, brittle, loose or missing belts.
Make sure mechanical linkages to engine sensors (throttle, gearshift
position, transmission, etc.) are secure and properly connected. See your vehicle’s service manual for locations.
Check all rubber hoses (radiator) and steel hoses (vacuum/fuel) for
leaks, cracks, blockage or other damage. Make sure all hoses are routed and connected properly.
Make sure all spark plugs are clean and in good condition. Check
for damaged, loose, disconnected or missing spark plug wires.
Make sure the battery terminals are clean and tight. Check for
corrosion or broken connections. Check for proper battery and charging system voltages.
Check all electrical wiring and harnesses for proper connection.

General Code Retrieval Procedures
OBD1 SYSTEMS / OBD2 SYSTEMS
Procedures for Retrieving Diagnostic Trouble Codes from OBD1 systems are vehicle manufacturer specific. Each manufacturer uses their own procedure.
Procedures for retrieving Diagnostic Trouble Codes from OBD2 systems are generic, and apply to all vehicles equipped with OBD2 systems.
From the following list, select the procedure that applies to your vehicle’s OBD system, and proceed to appropriate section for detailed code retrieval procedures.
OBD1 SYSTEMS
Most cars and light trucks (under 8500 GW) sold in the U.S. from early 1980’s to 1995 are equipped with what is known as the first generation of On-Board Diagnostics or “OBD1”.
If your Chrysler/Jeep, Ford, GM or Toyota vehicle, (1995 and older)
is equipped with an ‘OBD1 System”, proceed to the proper section as indicated below, for a detailed application list and code retrieval procedures:
CHRYSLER/JEEP .............................page 68

The Enhanced CanOBD2&1 Scan Tool is designed to work on all OBD2 compliant vehicles. All 1996 and newer vehicles (cars and light trucks) sold in the United States are OBD2 compliant.
Federal law requires that all 1996 and newer cars and light trucks sold in the United States must be OBD2 compliant; this includes all Domestic, Asian and European vehicles.
Some 1994 and 1995 vehicles are OBD2 compliant. To find out if a 1994 or 1995 vehicle is OBD2 compliant, check the following:
1. The Vehicle Emissions Control Information (VECI) Label. This
label is located under the hood or by the radiator of most vehicles. If the vehicle is OBD2 compliant, the label will state “OBD II
Certified.”

On some Asian and European vehicles the DLC is located behind the “ashtray” (the ashtray must be removed to access it) or on the far left corner of the dash. If the DLC cannot be located, consult the vehicle’s service manual for the location.
DIAGNOSTIC TROUBLE CODES (DTCs)
Diagnostic Trouble Codes (DTCs) are meant to guide you to the proper service procedure in the vehicle’s service manual. DO NOT replace parts based only on DTCs without first consulting the vehicle’s service manual
Diagnostic Trouble
Codes (DTCs) are
codes that identify a
specific problem area.
for proper testing procedures for that particular system, circuit or component.
DTCs are alphanumeric codes that are used to identify a problem that is present in any of the systems that are monitored by the on-board computer (PCM). Each trouble code has an assigned message that identifies the circuit, component or system area where the problem was found.
OBD2 diagnostic trouble codes are made up of five characters:
The 1st character is a letter. It identifies the “main system” where
the fault occurred (Body, Chassis, Powertrain, or Network).
The 2nd character is a numeric digit. It identifies the “type” of code
(Generic or Manufacturer-Specific).
Generic DTCs are codes that are used by all vehicle manufacturers. The standards for generic DTCs, as well as their definitions, are set by the Society of Automotive Engineers (SAE).
Manufacturer-Specific DTCs are codes that are controlled by the vehicle manufacturers. The Federal Government does not require vehicle manufacturers to go beyond the standardized generic DTCs in order to comply with the new OBD2 emissions standards. However, manufacturers are free to expand beyond the standardized codes to make their systems easier to diagnose.
The 3rd character is a numeric digit. It identifies the specific
system or sub-system where the problem is located.
The 4th and 5th characters are numeric digits. They identify the
section of the system that is malfunctioning.

DTCs and MIL Status
When the vehicle’s on-board computer detects a failure in an emissions-related component or system, the computer’s internal diagnostic program assigns a diagnostic trouble code (DTC) that points to the system (and subsystem) where the fault was found. The diagnostic program saves the code in the computer’s memory. It records a “Freeze Frame” of conditions present when the fault was found, and lights the Malfunction Indicator Lamp (MIL). Some faults require detection for two trips in a row before the MIL is turned on.
The “Malfunction Indicator Lamp” (MIL) is the accepted term used to describe the lamp on the dashboard that lights to warn the driver that an emissions-related fault has been found. Some manufacturers may still call this lamp a “Check Engine” or “Service Engine Soon” light.

CODE RETRIEVAL PROCEDURE
CODE RETRIEVAL PROCEDURE
Retrieving and using Diagnostic Trouble Codes (DTCs) for
troubleshooting vehicle operation is only one part of an
overall diagnostic strategy.
Never replace a part based only on the DTC definition. Each DTC has a set of testing procedures, instructions and flow charts that must be followed to confirm the location of the problem. This information is found in the vehicle's service manual. Always refer to the vehicle's service manual for detailed testing instructions.
Check your vehicle thoroughly before performing any test. See BEFORE YOU BEGIN on page 18 for details.
ALWAYS observe safety precautions whenever working on a vehicle. See Safety Precautions on page 3 for more information.
1. Turn the ignition OFF.
2. Locate the vehicle's 16-pin Data Link
Connector (DLC). See page 21 for connector location.
Some DLCs have a plastic cover that must be removed before connecting the CanOBD2&1 Scan Tool cable connector.
If the CanOBD2&1 Scan Tool is ON, turn it OFF by pressing the POWER/LINK connecting the CanOBD2&1 Scan Tool to the DLC.
3. Connect the OBD II Cable to the CanOBD2&1 Scan Tool, then
connect to the vehicle’s DLC.
If you have problems connecting the cable connector to the DLC,
rotate the connector 180° and try again.
If you still have problems, check the
pins on the CanOBD2&1 Scan Tool’s DLC and on the vehicle’s DLC.
4. When the CanOBD2&1 Scan Tool’s
cable connector is properly connected to the vehicle’s DLC, the unit automati­cally turns ON, and the display shows instructions for linking to the vehicle’s on-board computer.

CODE RETRIEVAL PROCEDURE
If the unit does not power on automatically when connected to
the vehicle’s DLC connector, it usually indicates there is no power present at the vehicle’s DLC connector. Check your fuse panel and replace any burned-out fuses.
If replacing the fuse(s) does not correct the problem, consult
your vehicle’s repair manual to identify the proper computer (PCM) fuse/circuit, and perform any necessary repairs before proceeding.
5. Turn the ignition on. DO NOT start the engine.
6. Press and release the CanOBD2&1 Scan Tool’s POWER/LINK
button.
The CanOBD2&1 Scan Tool will
automatically start a check of the vehicle’s computer to determine which type of communication protocol it is using. When the CanOBD2&1 Scan Tool identifies the computer’s communication protocol, a communication link is es­tablished. The protocol type used by the vehicle’s computer is shown on the display.
A PROTOCOL is a set of rules and procedures for regulating data transmission between computers, and between testing equipment and computers. As of this writing, five different types of protocols (ISO 9141, Keyword 2000, J1850 PWM, J1850 VPW and CAN) are in use by vehicle manufacturers. The CanOBD2&1 Scan Tool automatically identifies the protocol type and establishes a communication link with the vehicle’s computer.
7. After approximately 10~60 seconds, the CanOBD2&1 Scan Tool will
retrieve and display any Diagnostic Trouble Codes, Monitor Status
and Freeze Frame Data retrieved from the vehicle’s computer memory.
If the CanOBD2&1 Scan Tool fails
to link to the vehicle’s computer a “Linking Failed” message shows on the CanOBD2&1 Scan Tool’s display.
- Verify the connection at the DLC
and verify the ignition is ON.
- Turn the ignition OFF, wait 5 seconds, then turn back ON to
reset the computer.
- Ensure your vehicle is OBD2 compliant. See VEHICLES
COVERED on page 21 for vehicle compliance verification information.

CODE RETRIEVAL PROCEDURE
The CanOBD2&1 Scan Tool will
automatically re-link to the vehicle’s computer every 30 seconds to refresh the data being retrieved. When data is being refreshed, the message “One moment Auto – link in progress” is shown on the display. This action repeats as long as the CanOBD2&1 Scan Tool is communicating with the vehicle’s computer.
The CanOBD2&1 Scan Tool will
display a code only if codes are present in the vehicle’s computer memory. If no codes are present, a “No DTC’s are presently stored in the vehicle’s computer” message is displayed.
The CanOBD2&1 Scan Tool is capable of retrieving and storing
up to 32 codes in memory, for immediate or later viewing.
8. To read the display:
Refer to DISPLAY FUNCTIONS on page 12 for a description of display elements.
A visible icon indicates that the CanOBD2&1 Scan Tool is
being powered through the vehicle’s DLC connector.
A visible icon indicates that the CanOBD2&1 Scan Tool is
linked to (communicating with) the vehicle’s computer.
The I/M Monitor Status icons indicate the type and number of
Monitors the vehicle supports, and provide indications of the current status of the vehicle’s Monitors. A solid Monitor icon indicates the associated Monitor has run and completed its testing. A blinking Monitor icon indicates the associated Monitor has not run and completed its testing.
The upper right hand corner of the
display shows the number of the code currently being displayed, the total number of codes retrieved, the type of code (G = Generic; M = Enhanced or Manufacturer specific), and whether or not the displayed code commanded the MIL on. If the code being displayed is a PENDING code, the PENDING icon is shown.
The Diagnostic Trouble Code (DTC) and related code definition
are shown in the lower section of the display.

In the case of long code definitions, or when viewing Freeze Frame data, a small arrow is shown in the upper/lower right-hand corner of the code display area to indicate the presence of additional information. Use the additional information.
If a definition for the currently displayed code is not available, an advisory message shows on the CanOBD2&1 Scan Tool’s display.
9. Read and interpret Diagnostic Trouble Codes/system condition
using the display and the green, yellow and red LEDs.
The green, yellow and red LEDs are used (with the LCD display) as visual aids to make it easier to determine engine system conditions.
Green LED – Indicates that all
engine systems are “OK” and operating normally. All Monitors supported by the vehicle have run and performed their diagnostic testing, and no trouble codes are present. A zero will show on the CanOBD2&1 Scan Tool’s display, and all Monitor icons will be solid.
Yellow LED – Indicates one of the following conditions:
A. A PENDING CODE IS PRESENT –
If the yellow LED is illuminated, it may indicate a Pending code is present. Check the CanOBD2&1 Scan Tool’s display for confirmation. A Pending code is confirmed by the presence of a numeric code and the word PENDING on the CanOBD2&1 Scan Tool’s display.
B. MONITOR NOT RUN STATUS – If
the CanOBD2&1 Scan Tool’s display shows a zero (indicating there are no DTC’s present in the vehicle’s computer memory), but the yellow LED is illuminated, it may be an indication that some of the Monitors supported by the vehicle have not yet run and completed their diagnostic testing. Check the CanOBD2&1 Scan Tool’s display for confirmation. All Monitor icons that are blinking have not yet run and completed their diagnostic testing; all Monitor icons that are solid have run and completed their diagnostic testing.

Red LED – Indicates there is a
problem with one or more of the vehicle’s systems. The red LED is also used to indicate that DTC(s) are present (displayed on the CanOBD2&1 Scan Tool’s screen). In this case, the Malfunction Indicator (Check Engine) lamp on the vehicle’s instrument panel will be illuminated.
DTC’s that start with “P0”, “P2” and
some “P3” are considered Generic (Universal). All Generic DTC definitions are the same on all OBD2 equipped vehicles. The CanOBD2&1 Scan Tool automatically displays the code definitions for Generic DTC’s.
If the Generic definition for the currently displayed code is not available, an advisory message shows on the CanOBD2&1 Scan Tool’s display.
DTC’s that start with “P1” and some
“P3” are Manufacturer specific codes and their code definitions vary with each vehicle manufacturer. When a Manufacturer specific DTC is retrieved, the LCD display shows a list of vehicle manufacturers. Use the UP
and DOWN buttons, as necessary, to highlight the appropri­ate manufacturer, then press the ENTER/LD correct code definition for your vehicle.
