SAFETY PRECAUTIONS To prevent accidents that could possibly result in serious injury and/or damage to vehicles and/or test equipment, carefully follow all safety rules and test procedures when working on vehicles. Always wear ANSI approved eye protection. Always operate the vehicle in a well-ventilated area. Do not breath exhaust gases — they are very hazardous. Always keep yourself, tools and test equipment away from all moving or hot engine parts.
Always use caution when working around the ignition coil, distributor cap, ignition wires, and spark plugs. These components can produce High Voltage while the engine is running. Battery electrolyte is sulfuric-acid and is extremely caustic. If contacted, rinse with water or neutralize with a mild base (i.e. baking soda). If contacted in eyes, flush with water and call a physician immediately. Never smoke or have open flames near vehicle.
Section 1 Quick Start 1.1 Introduction Congratulations! You've purchased an automotive scanner that can unlock the fault code information stored in the on-board computer(s) of your car or light truck. This information gives you the power to identify and repair problems that may arise with the operation of your vehicle's engine. Cars and trucks cannot completely diagnose their problems, and no scanner available can tell you with pinpoint accuracy what is wrong with the vehicle.
The next step in the diagnostic process is to test systems and parts that are suspected to be defective. This testing process may include: • Sensors • Fuel injection system • Ignition system • Vacuum & Pressure systems Even when working on modern, computer-controlled vehicles there is no substitute for good old-fashioned troubleshooting. Once you have isolated and repaired the failed problem(s), you can use your AutoScanner to clear the codes from the computer's memory.
To erase DTCs, press the ERASE key on the AutoScanner. This function must be performed with the KOEO - Do not START engine. Main Menu 2)Erase Codes ! Note: In addition to clearing DTCs, the Erase Codes function may reset the status of the I/M System Monitors to “Not Ready.” ! “Hard” codes are codes that can be removed only by repairing the faults that they cause; therefore, hard codes will remain in the computer’s memory until the condition is repaired.
Section 2 Tool Basics 2.1 Tool Features The OBD II AutoScanner was developed by experts in the automotive service industry to help diagnose vehicles and assist in troubleshooting procedures. The AutoScanner will perform OBD II functions on compliant vehicles 1994 and newer. No batteries are needed; power is provided from the vehicle’s data link connector (DLC). B OBD II connector & B D H cable with strain-relief. C Two-line LCD display. D READ key - performs the Read Codes function.
2.1.1 Display The AutoScanner uses a two-line liquid crystal display (LCD). The top line contains 10 characters to show function headings, numbers and user prompts. The bottom line contains 20 characters to display selections and code information. Messages longer than the lines will scroll continuously across the display from right to left. Display contrast adjustment is accessed from the Tool Setup/Test menu. 2.1.
The AutoScanner may ask a question which requires a YES or NO response from the user. Press either the YES key or NO key when the condition arises. 2.3 Diagnostic Link Connector and Location The AutoScanner communicates with the vehicle’s computer modules via a Diagnostic Link Connector (DLC). OBD II regulations define the physical and electrical specification for the DLC. Certain pins in the connector are dedicated for power and ground. The DLC is also referred to as a J1962 connector.
2.4 Diagnostic Trouble Codes (DTCs) Diagnostic Trouble Codes (DTCs) consist of a three-digit code preceded by an alphanumeric designator. When the on-board computer recognizes and identifies a problem, a DTC for that fault is stored in memory. These codes are intended to help the user determine the root cause of a problem. The format and type of DTCs is summarized on the next page. J2012 is a standard for all DTCs established by the Society of Automotive Engineers (SAE).
2.5 This Manual This manual provides step-by-step procedures to operate the OBD II AutoScanner. Specific diagnostics for the vehicle may be found in applicable service manuals listed in Section 2.6. Information about OBD II can be found in Appendix B - OBD II Background. Warnings, Cautions and Notes These are identified with the following symbols. Please read and understand the Safety Precautions and adhere to them while testing the vehicle.
2.6 Vehicle Service Information Vehicle service manuals containing additional diagnostic information are available at most auto parts stores or the local library.

3.2 Read Codes The Read Codes function retrieves Diagnostic Trouble Codes (DTCs) from the vehicle’s computer modules. This function can be performed with 1)Read Codes the KOEO or KOER. Main Menu ] 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.
If one DTC is retrieved, the AutoScanner will display the DTC number and type (MIL or pending) on the top line, and the definition on the bottom. If more than one DTC is present, the top line will also display the code index (n/x), i.e. 1 of 3. This and the DTC number will alternate on the display while the bottom line shows the definition.

To Erase Codes, press the ERASE key. This function can also be run by selecting Erase Codes from the Main Menu. Main Menu 2)Erase Codes Before erasing codes, the AutoScanner will perform the Read Codes function and display the number of DTCs stored in the vehicle’s computer memory. ! CAUTION! Avoid Cooling Fan! It May Turn On During Test. If no DTCs are present, then press ENTER to return to the Main Menu.
3.4 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.
3.5 I/M Monitors The I/M Readiness (Inspection and Maintenance) function is used to check the operations of the Emission System on OBDII vehicles. I/M Readiness is an excellent function to use prior to having a vehicle inspected for compliance to a state emissions program. During normal driving conditions, the vehicle’s computer scans the emission system.

Section 4 ing t o o h s e l b u o Tr 4.1 Vehicle Inspection Many problems can be found by performing a visual and “hands-on” under-the-hood inspection before starting any diagnostic procedure. • Has the vehicle been serviced recently? Sometimes things are reconnected in the wrong place, or not at all. • Do not take shortcuts. Inspect hoses and wiring which may be difficult to see because of location (under air cleaner housing, alternators and similar components).
• Carefully inspect electrical connectors for: - Corrosion or foreign debris on pins. - Bent or damaged pins. - Recessed contacts not seated properly in housing. - Bad wire crimps to terminals. ! Connector problems are common in vehicles. Inspect carefully. Some connectors use a special grease, called dielectric grease, on the contacts to prevent corrosion. Do not remove. If required, apply more grease to the connector. The grease can be obtained from a dealership or auto parts store. 4.
4.3 Link Errors or Erroneous Data A Link Error occurs if the vehicle’s computer(s) stops communicating with the AutoScanner. When this Try Again? happens, the AutoScanner prompts the user to try again. Press the YES key to try again or the NO key to return to the Main Menu. Link Error If the AutoScanner displays Link Errors when attempting to read or erase codes, check the following: • Verify ignition key is ON - not in the ACCESSORIES position.
Appendix A Glossary A/C: Air Conditioning. 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. A typical ideal A/F ratio is 14.7:1. AC Clutch Relay: The PCM uses this relay to energize the A/C clutch, turning the A/C system on or off. AC Pressure Sensor: Measures air conditioning refrigerant pressure and sends a voltage signal to the PCM.
CKP REF: Crankshaft Position Reference. CKP: Crankshaft Position. See CPS. Closed Loop (C/L): A feedback system that uses the O2 sensor(s) to monitor the results of combustion. Based on the signal(s) from the O2 sensor(s), the PCM modifies the air/fuel mixture to maintain optimum performance with lowest emissions. In closed loop mode, the PCM can “fine tune” control of a system to achieve an exact result. CO: Carbon Monoxide Continuous Memory Codes: See Pending Codes. CPS: Crankshaft Position Sensor.
throttle position, coolant temperature, engine load, vehicle speed, Park/Neutral switch position, and knock sensorcondition. EVAP: Evaporative Emissions System. Hall Effect Sensor: Any of a type of sensor utilizing a permanent magnet and a transistorized Hall Effect switch. Hall Effect type sensors may be used to measure speed and position of the crankshaft or camshaft — for spark timing and fuel injector control. HO2S: Heated Oxygen Sensor. See O2S. IAC: Idle Air Control.
NOx: Oxides of Nitrogen. A pollutant. The EGR system injects exhaust gases into the intake manifold to reduce these gases at the tailpipe. O2S: Oxygen Sensor. Generates a voltage of 0.6 to 1.1 volts when the exhaust gas is rich (low oxygen content). The voltage changes to 0.4 volts or less when the exhaust gas is lean (high oxygen content). This sensor only operates after it reaches a temperature of approximately 349°C (660°F).
Sensor: Any device that reports information to the PCM. The job of the sensor is to convert a parameter such as engine temperature into an electrical signal that the PCM can understand. Sensor 1: A standard term used to identify the location of oxygen sensors. Sensor 1 is located upstream of the catalytic converter. See O2S, Bank 1, Bank 2. Sensor 2: A standard term used to identify the location of oxygen sensors. Sensor 2 is located downstream of the catalytic converter. See O2S, Bank 1, Bank 2.
Appendix B A b out O B D II OBD II In 1994, manufacturers began equipping vehicles with a new class of computer technology which puts more processing power in the vehicle than ever before. It is called On-Board Diagnostics, Second Generation (OBD II) and offers increased system monitoring and diagnostic information. Beginning January 1, 1996, vehicles sold in the U.S. are required to be OBD II compliant. However, a few vehicles were exempt since no changes were made to the engine.
What does the computer control The main control areas of the vehicle computer are fuel delivery, idle speed, spark advance, and emission controls. Some on-board computers may also control the transmission, brakes, and suspension systems as well. What has not changed A computer-controlled engine is very similar to the older, non-computerized engine. It is still an internal combustion engine with pistons, spark plugs, valves, and camshaft(s).
it uses fuel injectors (either in a throttle body or at each intake port). Fuel injectors are far more precise than carburetor jets, and create a much finer fuel “mist” for better combustion and increased efficiency. In addition, most fuel injection systems have ways of measuring exactly how much air is entering the engine, and can calculate the proper air/fuel ratio using lookup tables. Computers no longer have to “estimate” how much air the engine is using.
About Diagnostic Trouble Codes (DTCs) Engine computers can find problems The computer systems in today’s vehicles do more than control engine operations—they can help you find problems, too! Special testing abilities are permanently programmed into the computer by engineers. These tests check the components connected to the computer which are used for (typically): fuel delivery, idle speed control, spark timing, emission systems, and transmission shifting. Mechanics have used these tests for years.
About the Malfunction Indicator Lamp (MIL) All OBD II compliant vehicles have a “Malfunction Indicator Lamp” or MIL. In the past, the MIL has been referred to as a “Check Engine” or “Service Engine Soon” light. Normal operation The engine computer turns the MIL ON and OFF as needed.
