PLEASE NOTE: The Reader will NOT work  with ABS or SRS (air bag) systems and is NOT compatible with hybrid or electric vehicles, it can ONLY deal with engine management faults. You will only be able to turn an engine warning/fault light OFF when the problem causing the warning light has been resolved.

Safety Precautions and Warnings

To prevent personal injury or damage to vehicles and/or the code reader, read this instruction manual first and observe the following safety precautions at a minimum whenever working on a vehicle:

• Always perfin automotive testing in a safe environment.
• Wear safety eye protection
• Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot engine parts.
• Operate the vehicle in a well ventilated work area: Exhaust gases are poisonous.
• Put blocks in front of the drive wheels and never leave the vehicle unattended while running tests.
• Use extreme caution when working around the ignition coil, distributor cap, ignition wires and spark plugs. These components create hazardous voltages when the engine is running.
• Put the transmission in PARK (for automatic transmission) or NEUTRAL (for manual transmission) and make sure the parking brake is engaged.
• Keep a fire extinguisher suitable for gasoline/chemical/ electrical fires nearby.
• Don’t connect or disconnect any test equipment while the ignition is on or the engine is running.
• Keep the code reader dry, clean, free from oil/water or grease. Use a mild detergent on a clean cloth to clean the outside of the code reader, when necessary.

General Information

2.1 On-Board Diagnostics (OBD) II
The first generation of On-Board Diagnostics (called OBD I) was developed by the California Air Resources Board (ARB) and implemented in 1988 to monitor some of the emission control components on vehicles. As technology evolved and the desire to improve the On-Board Diagnostic system increased, a new generation of On-Board Diagnostic system was developed. This second generation of On-Board Diagnostic regulations is called “OBD II”.
The OBD II system is designed to monitor emission control systems and key engine components by performing either continuous or periodic tests of specific components and vehicle conditions. When a problem is detected, the OBD II  system turns on a warning lamp (MIL) on the vehicle instrument panel to alert the driver typically by the phrase of “Check Engine or “Service Engine Soon”. The system will also store important information about the detected  malfunction so that a technician can accurately find and fix the problem. Here below follow three pieces of such valuable information:

1. Whether the Malfunction Indicator Light (MIL) is commanded ‘on’ or ‘off’;
2. Which, if any, Diagnostic Trouble Codes (DTCs) are stored;
3. Readiness Monitor status.

2.2 Diagnostic Trouble Codes (DTCs)
OBD II Diagnostic Trouble Codes are codes that are stored by the on-board computer diagnostic system in response to a problem found in the vehicle. These-codes identify a particular problem area and are intended to provide you with a  guide as to where a fault might be occurring within a vehicle. OBD II Diagnostic Trouble Codes consist of a five-digit alphanumeric code. The first character, a letter, identifies which control system sets the code. The other four characters, all numbers, provide additional information on where the DTC originated and the operating conditions that caused it to set. Here below is an example to illustrate the structure of the digits:

2.3 Location of the Data Link Connector (DLC)
The DLC (Data Link Connector or Diagnostic Link Connector) is the standardized 16-cavity connector where diagnostic code readers interface with the vehicle’s on-board computer. The DLC is usually located 12 inches from the  cENTER/EXIT of the instrument panel (dash), under or around the driver’s side for most vehicles. If Data Link Connector is not located under dashboard, a label should be there telling location. For some Asian and European vehicles,  the DLC is located behind the ashtray and the ashtray must be removed to access the connector. If the DLC cannot be found, refer to the vehicle’s service manual for the location.

2.4 OBD II Readiness Monitors
An important part of a vehicle’s OBD II system is the Readiness Monitors, which are indicators used to find out if all of the emissions components have been evaluated by the OBD II system. They are running periodic tests on specific  systems and components to ensure that they are performing within allowable limits.
Currently, there are eleven OBD II Readiness Monitors (or 1/M Monitors). Not all monitors are supported by all vehicles and the exact number of monitors in any vehicle depends on the motor vehicle manufacturer’s emissions control strategy.
Continuous Monitors — Some of the vehicle components or systems are continuously tested by the vehicle’s O8D II system, while others are tested only under specific vehicle operating conditions. The continuously monitored components listed below are always ready:

1. Misfire
2. Fuel System
3. Comprehensive Components (CCM)

Once the vehicle is running, the O8D II system is continuously checking the above components, monitoring key engine sensors, watching for engine misfire, and monitoring fuel demands.
Non-Continuous Monitors — Unlike the continuous monitors, many emissions and engine system components require the vehicle to be operated under specific conditions before the monitor is ready. These monitors are termed  non- continuous monitors and are listed below:

1. EGR System
2. O2 Sensors
3. Catalyst
4. Evaporative System
5. O2 Sensor Heater
6. Secondary air
7. Heated Catalyst
8. A/C system

2.5 OBD II Monitor Readiness Status
OBD II systems must indicate whether or not the vehicle’s PCM’s monitor system has completed testing on each component.
Components that have been tested will be reported as “Ready”, or “Complete”, meaning they have been tested by the OBD II system. The purpose of recording readiness status is to allow inspectors to determine if the vehicle’s OBD II system has tested all the components and/or systems.
The powertrain control module (PCM) sets a monitor to “Ready” or “Complete” after an appropriate drive cycle has been performed. The drive cycle that enables a monitor and sets readiness codes to “Ready” varies for each individual  monitor. Once a monitor is set as “Ready” or “Complete”, it will remain in this state. A number of factors, including erasing of diagnostic trouble codes (DTCs) with a code reader or a disconnected battery, can result in Readiness Monitors being set to “Not Ready”. Since the three continuous monitors are constantly evaluating, they will be reported as “Ready” all of the time. If testing of a particular supported non-continuous monitor has not been completed, the monitor  status will be reported as “Not Complete” or “Not Ready.”
In order for the O8D monitor system to become ready, the vehicle should be driven under a variety of normal operating conditions. These operating conditions may include a mix of motorway driving and stop and go, city type driving,  and at least one overnight-off period. For specific information on getting your vehicle’s O8D monitor system ready, please consult your vehicle owner’s manual.

2.6 OBD II Definitions
Powertrain Control Module (PCM) — OBD II terminology for the on-board computer that controls engine and drive train.
Malfunction Indicator Light (MIL) — Malfunction Indicator Light (Service Engine Soon, Check Engine) is a term used for the light on the instrument panel. It is to alert the driver and/or the repair technician that there is a problem with  one or more of vehicle’s systems and may cause emissions to exceed federal standards. If the MIL illuminates with a steady light, it indicates that a problem has been detected and the vehicle should be serviced as soon as possible. Under  certain conditions, the dashboard light will blink or flash. This indicates a severe problem and flashing is intended to discourage vehicle operation. The vehicle onboard diagnostic system can not tum the MIL off until the necessary repairs are completed or the condition no longer exists.
DTC — Diagnostic Trouble Codes (OTC) that identify which section of the emission control system has malfunctioned.
Enabling Criteria — Also termed Enabling Conditions. They are the vehicle- specific events or conditions that must occur within the engine before the various monitors will set, or run. Some monitors require the vehicle to follow a  prescribed “drive cycle” routine as part of the enabling criteria. Drive cycles vary among vehicles and for each monitor in any particular vehicle.
OBD II Drive Cycle — A specific mode of vehicle operation that provides conditions required to set all the readiness monitors applicable to the vehicle to the “ready” condition. The purpose of completing an 080 II drive cycle is to force the  vehicle to run its onboard diagnostics. Some form of a drive cycle needs to be performed after DTCs have been erased from the PCM’s memory or after the battery has been disconnected. Running through a vehicle’s complete drive  cycle will “set” the readiness monitors so that future faults can be detected. Drive cycles vary depending on the vehicle and the monitor that needs to be reset. For vehicle specific drive cycle, consult the vehicle’s Owner’s Manual.

Freeze Frame Data — When an emissions related fault occurs, the OBD II system not only sets a code but also records a snapshot of the vehicle operating parameters to help in identifying the problem. This set of values is referred to as  Freeze Frame Data and may include important engine parameters such as engine RPM, vehicle speed, air flow, engine load, fuel pressure, fuel trim value, engine coolant temperature, ignition timing advance, or closed loop status.

3. 7 Vehicle Coverage
The SWOBD4 OBD II Code Reader is specially designed to work with all OBD II compliant vehicles, including those equipped with the next generation protocol- Control Area Network (CAN). It is required that petrol vehicles manufactured during and after 1996 and diesel vehicles manufactured during and after 2004 ( cars and light trucks) must be OBD II compliant.
A small number of 1994 and 1995 model year petrol vehicles are O8D II compliant. To verify if a 1994 or 1995 vehicle is OBD II compliant, check the Vehicle Emissions Control Information (VECI) Label which is located under the hood or  by the radiator of most vehicles. If the vehicle is OBD II compliant, the label will designate “OBD II Certified”. Additionally, Government regulations mandate that all O8D II compliant vehicles must have a “common” sixteen-pin Data  Link Connector (DLC).
For your vehicle to be O8D II compliant it must have a 16-pin DLC (Data Link Connector) under the dash and the Vehicle Emission Control Information Label must state that the vehicle is OBD II compliant.
