1. Safety Precautions and WarningsTo prevent personal injury or damage to vehicles and/or the scan tool, read thisinstruction manual first and observe the following safety precautions wheneverworking on a vehicle:• Always perform automotive testing in a safe environment.• Wear safety eye protection that meets the required standards.• Keep clothing, hair, hands, tools, test equipment etc away from allmoving or hot engine parts.• Operate the vehicle in a well ventilated work area. Exhaust gasesare poisonous.• Put blocks in front of the drive wheels and never leave the vehicleunattended while running tests.• Use extreme caution when working around the ignition coil, distributorcap ignition wires and spark plugs. These components createhazardous 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 firesnearby.• Don’t connect or disconnect any test equipment while the ignition is onor the engine is running.• Don’t connect or disconnect any test equipment while the ignition is onor the engine is running.• Keep the scan tool dry, clean, free from oil/water or grease. Use a milddetergent on a clean cloth to clean the outside of the scan tool whennecessary.2. General InformationThe first generation of On-Board Diagnostics called OBDI were developed bythe California Air Resources Board (ARB) and implemented in 1988 to monitorsome of the emission control components on vehicles. As technology evolvedand the desire to improve the On-Board Diagnostic system increased, a newgeneration of On-Board Diagnostic System was developed. This secondgeneration of On-Board Diagnostic regulations is called OBDII.The OBDII system is designed to monitor emission control systems and keyengine components and vehicle conditions. When a problem is detected, theOBDII system turns on a warning lamp (MIL) on the vehicle instrument panel toalert the driver typically by the phrase of “Check Engine” or “Service EngineSoon”. The system will also store important information about the detected

malfunction so that a technician can accurately find and fix the problem. Threesuch examples of this are:• Whether the Malfunction Indicator Light (MIL) is commanded “on” or“off”.• Which, if any, Diagnostics Trouble Codes (DTC’s) are stored.• Readiness Monitor Status.Diagnostic Trouble Codes (DTC’s)OBDII Diagnostic Trouble Codes are codes that are stored by the On-BoardComputer Diagnostic System in response to a problem found in the vehicle.These codes identify a particular problem area and are intended to provide youwith a guide as to where a fault might be occurring within a vehicle.OBDII Diagnostic Trouble Codes consist of a five digit alphanumeric code. Thefirst character, a letter, identifies which control system sets the code. Theother four characters, all numbers, provide additional information on where theDTC originated and the operating conditions that caused it to set.Location of the Data Link Connector (DLC)The DLC (Data Link Connector or Diagnostic Link Connector) is thestandardized 16-cavity connector where diagnostic scan tools interface withthe vehicle’s On-Board Computer. The DLC is usually located 12 inches fromthe centre of the instrument panel (dash), under or around the driver’s side formost vehicles. If the DLC is not located under the dashboard, there should bea label telling the location. For some Asian and European vehicles, the DLC islocated behind the ashtray and this must be removed to access the connector.If the DLC cannot be found, refer to the vehicle’s service manual for thelocation.OBDII Readiness MonitorsAn important part of a vehicle’s OBDII system is the Readiness Monitors, whichare indicators used to find out if all the emission components have beenevaluated by the OBDII system. They are running periodic tests on specificsystems and components to ensure that they are performing within allowablelimits.Continuous MonitorsSome of the vehicle components or systems are continuously tested by thevehicle’s OBDII system, while others are tested only under specific vehicle

operating conditions. The continuously monitored components listed below arealways ready:• Misfire• Fuel System• Comprehensive Components (CCM)Once the vehicle is running, The OBDII system is continuously checking theabove components, monitoring key engine sensors, watching for engine misfireand monitoring fuel demands.Non-Continuous MonitorsUnlike the continuous monitors, many emissions and engine systemcomponents require the vehicle to be operated under specific conditions beforethe monitor is ready. These monitors are termed non-continuous monitors andare listed below:• EGR System• O2 Sensors• Catalyst• Evaporative System• O2 Sensor Heater• Secondary Air• Heated Catalyst• A/C SystemOBDII Monitor Readiness StatusOBDII systems must indicate whether or not the vehicle’s PCM’s monitor systemhas completed testing on each component. Components that have beentested will be reported as “Ready” or “Complete” meaning they have beentested by the OBDII system. The purpose of recording readiness status is toallow inspectors to determine if the vehicles OBDII system has tested all thecomponents 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 thatenables a monitor and sets readiness codes to “Ready” varies for eachindividual monitor. Once a monitor is set as “Ready” or “Complete” it willremain in this state. A number of factors, including erasing of DiagnosticTrouble Codes (DTC’s) with a scan tool or a disconnected battery, can result inReadiness Monitors being set or “Not Ready”. Since the three continuousmonitors are constantly evaluating, they will be reported as “Ready” all of thetime. If testing of a particular supported non-continuous monitor has not been

completed, the monitor status will be reported as “Not Complete” or “NotReady”.In order for the OBD monitor system to become ready, the vehicle should bedriven under a variety of normal operating conditions. These operatingconditions may include a mix of motorway driving and stop and go, city typedriving, and at least one overnight-off period.For specific information on getting your vehicle’s OBD Monitor System Ready,please consult your vehicle owner’s manual.OBDII DefinitionsPowertrain Control Module (PCM) – OBDII terminology for the On-BoardComputer that controls engine and drive train.Malfunction Indicator Light (MIL) – Malfunction Indicator Light (ServiceEngine Soon/Check Engine) is a term for the light of the instrument panel. It isto alert the driver and/or the repair technician that there is a problem with oneor more of the vehicle’s systems and may cause emissions to exceedstandards. If the MIL illuminates with a steady light, it indicates that a problemhas been detected and the vehicle should be serviced as soon as possible.Under certain conditions, the dashboard light will blink or flash. This indicates asevere problem and flashing is intended to discourage vehicle operation. Thevehicle On-Board Diagnostic System cannot turn the MIL off until necessaryrepairs are completed or the condition no longer exists.Diagnostic Trouble Codes (DTC) – Identify which section of the EmissionControl System has malfunctioned.Enabling Criteria – Also termed Enabling Conditions. They are the vehiclespecific events or conditions that must occur within the engine before thevarious monitors will set, or run. Some monitors require the vehicle to follow aprescribed “drive cycle” routine as part of the enabling criteria. Drive cyclesvary among vehicles and for each monitor in any particular vehicle.OBDII Drive Cycle – A specific mode of vehicle operation that providesconditions required to set all the readiness monitors applicable to the vehicle to“Ready” condition. The purpose of completing an OBDII drive cycle is to forcethe vehicle to run its onboard diagnostics. Some drive cycle needs to beperformed after DTC’s have been erased from the PCM’s memory or after thebattery has been disconnected. Running through a vehicle’s complete drivecycle 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 bereset. For vehicle specific drive cycle, consult the vehicle’s owner manual.3.

It is required that all 2001 Petrol and newer and2004 Diesel and newer cars sold in the UK must be OBDII compliant (manyprior to this are also compliant).A small number of 1994 and 1995 model petrol vehicles are OBDII compliant.To verify if a 1994 or 1995 vehicle is OBDII compliant, check the VehicleEmissions Control Information (VECI) label which is located under the hood orby the radiator of most vehicles. If the vehicle is OBDII compliant, the label willdesignate “OBDII Certified”. Additionally, Government regulations mandate thatOBDII compliant vehicles must have a common 16pin Data Link Connector(DLC).For you vehicle to be OBDII compliant it must have a 16pin port under the dashand the Vehicle Emission Control Information Label must state that the vehicleis OBDII compliant or the car must use one of the standard protocols.Product TroubleshootingVehicle Linking Error – A communication error occurs if the scan tool failsto communicate with the vehicle’s ECU (Engine Control Unit). You need to dothe following to check:• Verify that the ignition is ON.

• Check if the scan tool’s OBDII connector is securely connected to thevehicle’s DLC.• Verify that the vehicle is OBDII compliant.• Turn the ignition off and wait for about 10 seconds, turn the ignitionback on and continue the testing.• Verify the control module is not defective.Operating Error – If the scan tool freezes, then an exception occurs or thevehicles ECU (Engine Control Unit) is too slow to respond to requests. Youneed to do the following to reset the tool:• Press and hold POWER button for at least 2 seconds to reset the scantool.• Turn the ignition off and wait for about 10 seconds. Turn the ignitionback to on and continue the testing.Scan tool doesn’t power up – if the scan tool won’t power up or operatesincorrectly in any other way, you need to do the following to check:• Check the scan tool’s OBDII connector is securely connect to thevehicles DLC• Check if the DLC pins are bent or broken. Clean the DLC pins ifnecessary.• Check vehicle battery to make sure it is still good with at least 8V.OBDII DiagnosticsWhen more than one Vehicle Control Module is detected by the scan tool, youwill be prompted to select the module where the data may be retrieved. Themost often to be selected are the Powertrain Control Module (PCM) andTransmission Control Module (TCM.CAUTION: Do not connect or disconnect any test equipment with ignition onor engine running.DTC LookupThe DTC Lookup function is used to search for definitions of DTC’s stored inthe built in DTC library.From Main Menu use UP/DOWN scroll button To select DTC Lookup and pressENTER button.

The number to the right indicates total number of items under this menu andsequence of highlighted item. The “?” to the right indicates help informationavailable. Press HELP button to view help information for selected item.From DTC Lookup menu, use LEFT/RIGHT button to move to the desiredcharacter use UP/DOWN button to change selected digit/character and pressENTER button to confirm.To view the DTC definition on screen. When DTC definition covers more thanone screen, use LEFT/RIGHT button to view additional information onprevious/next screens.For manufacturer specific codes, you need to select a vehicle make on anadditional screen to look for DTC definitions. If definition could not be found(SAE or Manufacturer Specific), the scan tool displays “DTC definition notfound”. Please refer to vehicle service manual.To view next or previous DTC in the built in DTC library, use UP/DOWN button.To enter another DTC, press ESC button to return to previous screen.To exit to MAIN MENU press ESC button.Reading CodesReading codes can be done with the key on engine off (KOEO) or with the keyon engine running (KOER).Stored codes are also known as “hard codes” or “permanent codes”. Thesecodes cause the control module to illuminate the malfunction indicator lamp(MIL) when emission-related fault occurs.Pending Codes are also referred to as “maturing codes” or “continuous monitorcodes”. They indicate problems that the control module has detected duringthe current or last driving cycle but are not considered serious yet. PendingCodes will not turn on the malfunction indicator lamp (MIL). If the fault does notoccur within a certain number of warm up cycles, the code clears from memory.Erasing CodesCAUTION: Erasing the Diagnostic Trouble Codes may allow the scan tool todelete not only the codes from the vehicle’s on board computer andmanufacturer specific enhanced data. Further, the I/M Readiness MonitorStatus for all vehicle monitors is reset to Not Ready or Not Complete status.

Do not release the codes before the system has been checked completely bya technician.This function is performed with key on engine off (KOEO). Do not start theengine.Viewing DataThe View Data function allows viewing of live or real time PID data of vehicle’scomputer module(s).To view live data, use UP/DOWN scroll button to select Live Data fromDiagnostic Menu and press ENTER button.Recording DataThe Record Data function allows recoding vehicle modules’ ParameterIdentification (PID) data to help diagnose intermittent vehicle problems. Arecording includes 5 frames of live data before trigger event and severalframes after trigger event.There are two trigger modes used to record data:• Manual Trigger – allows user to press ENTER button to start recording.• DTC Trigger – automatically records PID data when a fault that causesa DTC to set is detected by vehicle.CAUTION: DO NOT try to drive and operate the scan tool at the same time!Always have another person operate the scan tool while driving.Playing Back DataThe Playback Data function allows viewing of previously stored PID Data.Viewing Freeze Frame DataAllows you to view any previously freeze framed data.Retrieving I/M Readiness StatusI/M Readiness function is used to check the operations of the Emission Systemon OBDII compliant vehicles. It is an excellent function to use prior to having avehicle inspected for compliance to a state emissions program.Some latest vehicle models may support two types of I/M Readiness tests.

• Since DTC’s cleared – indicates status of the monitors since the DTC’sare erased.• This Drive Cycle – indicates status monitors since the beginning of thecurrent drive cycle.An I/M Readiness Status result of “NO’ does not necessarily indicate that thevehicle being tested will fail the state I/M inspection. For some states, one ormore such monitors may be allowed to be “Not Ready” to pass the emissionsinspection.OK – Indicates that a particular monitor being checked has completed itsdiagnostic testing.INC – Indicates that a particular monitor being checked has not completed itsdiagnostic testing.N/A – The monitor is not supported on that vehicle.O2 Monitor TestOBDII regulations set by SAE require that relevant vehicles monitor and test theoxygen (O2) sensors to identify problems related to fuel efficiency and vehicleemissions. These tests are not on-demand tests and they are doneautomatically when engine operating conditions are within specified limits.These tests results are saved in the on-board computers memory.The O2 Monitor Test function allows retrieval and viewing of O2 sensor monitortest results for the most recently performed tests form the vehicle’s on-boardcomputer.The O2 Monitor Test function is not supported by vehicles which communicateusing a controller area network (CAN). For O2 Monitor Test results of CANequippedvehicles, see chapter “On-Board Mon. Test”.On-Board Monitor TestThe On-Board Monitor Test is useful after servicing or after erasing a vehicle’scontrol module memory. The On-Board Monitor Test for non-CAN equippedvehicles retrieves and displays test results for emission related powertraincomponents and systems that are not continuously monitored. The On-BoardMonitor Test for CAN-equipped vehicles retrieves and displays test results foremission related powertrain components and systems that are and are notcontinuously monitored. Test and components IDs are determined by thevehicle manufacturer.Component Test

The Component Test function allows initiating a leak test for the vehicle’sEVAP system. The scan tool itself does not perform the leak test, butcommands the vehicle’s on-board computer to start the test. Different vehiclemanufacturers might have different criteria and methods for stopping the testonce it has been started. Before starting the Component Test, refer to thevehicle service manual for instructions to stop the test.Viewing Vehicle InformationThe Vehicle Info function enables retrieval of Vehicle Identification No. (VIN),Calibration ID Nos. (CINs), Calibration Verification Nos. (CVNs) and In-usePerformance Tracking on 2000 and newer vehicles that support Mode 9.Modules PresentThe Modules Present function allows viewing of the module IDs andcommunication protocols for OBDII modules in the vehicle.7.
