LAUNCH Professional 909 User Manual 1. Introduction Creader Professional 909 Diagnostic Tool is an evolutionary smart solution for passenger car diagnosis. It inherits from LAUNCH’s advanced diagnosing technology and is characterized by covering a wide range of vehicles, featuring powerful functions, and providing precise test result. It has the following functions and advantages: • Smart(Auto-Detect) Diagnosis: Once the tool and the vehicle are properly connected, the system starts auto-detect process.
LAUNCH Professional 909 User Manual A small number of 1994 and 1995 model year gasoline vehicles are OBD II compliant. To verify if a 1994 or 1995 vehicle is OBD II compliant, check the following: 1. Vehicle Emissions Control Information (VECI) Label. It 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”. 2.
LAUNCH Professional 909 User Manual 2. General Information 2.1 On-Board Diagnostics (OBD) I Note: With the exception of some 1994 and 1995 vehicles, most vehicles from 1982 to 1995 are equipped with some type of first generation On-Board Diagnostics. Beginning in 1988, California’s Air Resources Board (CARB), and later the Environmental Protection Agency (EPA) required vehicle manufacturers to include a self-diagnostic program in their on-board computers.
LAUNCH Professional 909 User Manual components. These components were causing an increase in emissions. • Because OBD I systems only detect failed components, the degraded components were not setting codes. • Some emissions problems related to degraded components only occur when the vehicle is being driven under a load. The emission checks being conducted at the time were not performed under simulated driving conditions.
LAUNCH Professional 909 User Manual 2.3 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.
LAUNCH Professional 909 User Manual P0201 - Injector circuit malfunction, Cylinder 1 2.4 Location of the Data Link Connector (DLC) The DLC (Data Link Connector or Diagnostic Link Connector) is typically a 16pin connector where diagnostic code readers interface with the vehicle’s onboard computer. The DLC is usually located 12 inches from the center of the instrument panel (dash), under or around the driver’s side for most vehicles.
LAUNCH Professional 909 User Manual 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. Potential DLC Location 2.5 OBD II Terminology The following terms and their definitions are related to OBD II systems.
LAUNCH Professional 909 User Manual complete its diagnostic testing are met. The “Trip Drive Cycle” for a particular Monitor begins when the ignition key is turned “On.” It is successfully completed when all the “Enabling Criteria” for the Monitor to run and complete its diagnostic testing are met by the time the ignition key is turned “Off.
LAUNCH Professional 909 User Manual limits. Currently, fifteen Monitors are supported by OBD II systems. Additional monitors may be added as a result of Government regulations as the OBD II system grows and matures. Not all vehicles support all fifteen Monitors. Additionally, some Monitors are supported by “spark ignition” vehicles only, while others are supported by “compression ignition” vehicles only. Monitor operation is either “Continuous” or “Non-Continuous,” depending on the specific monitor. 2.6.
LAUNCH Professional 909 User Manual This Monitor uses a Fuel System Correction program, called Fuel Trim, inside the on-board computer. Fuel Trim is a set of positive and negative values that represent adding or subtracting fuel from the engine. This program is used to correct for a lean (too much air/not enough fuel) or rich (too much fuel/not enough air) air-fuel mixture. The program is designed to add or subtract fuel, as needed, up to a certain percent.
LAUNCH Professional 909 User Manual signal to make corrections to the air/fuel mixture. If the exhaust gas has a large amount of oxygen (a lean air/fuel mixture), the oxygen sensor generates a “low” voltage signal. If the exhaust gas has very little oxygen (a rich mixture condition), the oxygen sensor generates a “high” voltage signal. A 450mV signal indicates the most efficient, and least polluting, air/fuel ratio of 14.7 parts of air to one part of fuel.
LAUNCH Professional 909 User Manual a Pending Code. The computer does not command the MIL on at this time. If the fault is sensed again on the second trip, the computer commands the MIL “On,” and saves the code in its long-term memory. 3. Catalyst Monitor The catalytic converter is a device that is installed downstream of the exhaust manifold. It helps to oxidize (burn) the unburned fuel (hydrocarbons) and partially burned fuel (carbon monoxide) left over from the combustion process.
LAUNCH Professional 909 User Manual temperatures must be kept below 2500°F. The EGR system recirculates small amounts of exhaust gas back into the intake manifold, where it is mixed with the incoming air/fuel mixture. This reduces combustion temperatures by up to 500°F. The computer determines when, for how long, and how much exhaust gas is recirculated back to the intake manifold. The EGR Monitor performs EGR system function tests at preset times during vehicle operation.
LAUNCH Professional 909 User Manual • It supplies the catalytic converter with the oxygen it needs to oxidize the carbon monoxide and hydrocarbons left over from the combustion process during engine warmup. • The extra oxygen injected into the exhaust stream also helps the catalytic converter reach operating temperature more quickly during warm-up periods. The catalytic converter must heat to operating temperature to work properly.
LAUNCH Professional 909 User Manual hydrocarbons to produce H2O and N2. The NOx Aftertreatment Monitor monitors the function of the NOx aftertreatment to ensure that tailpipe emissions remain within acceptable limits. The NOx Aftertreatment Monitor is supported by “compression ignition” vehicles only. The NOx Aftertreatment Monitor is a “Two-Trip” Monitor. If a fault is found on the first trip, the computer temporarily saves the fault in its memory as a Pending Code.
LAUNCH Professional 909 User Manual exhaust gas concentration in order to burn off the trapped particles (oxidizing the particles to form CO2 and water). The computer monitors the efficiency of the filter in trapping particulate matter, as well as the ability of the filter to regenerate (self-clean). The PM Filter Monitor is supported by “compression ignition” vehicles only. The PM Filter Monitor is a “Two-Trip” Monitor.

LAUNCH Professional 909 User Manual Note: 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. There are two types of DTCs used for emissions-related faults: Type “A” and Type “B.” Type “A” codes are “One-Trip” codes; Type “B” DTCs are usually TwoTrip DTCs.
LAUNCH Professional 909 User Manual before the MIL is turned “Off.” These are trips where the engine load, RPM and temperature are similar to the conditions present when the fault was first found. Note: After the MIL has been turned off, DTCs and Freeze Frame data stay in the computer’s memory. • Erasing the DTCs from the computer’s memory can also turn off the MIL. If a Diagnostic Tool or Scan Tool is used to erase the codes, Freeze Frame data will also be erased.
