LAUNCH TOUCH PRO ELITE User Manual 1. Introduction TOUCH PRO ELITE Diagnostic Tool is an evolutionary smart solution for passenger car diagnosis. It inherits LAUNCH’s advanced diagnosing technology and is characterized by covering a wide range of vehicles and providing precise test result and powerful functions. 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 TOUCH PRO ELITE User Manual hood or by the radiator of most vehicles. If the vehicle is OBD II compliant, the label will designate “OBD II Certified”. 2. Government regulations mandate that all OBD II compliant vehicles must have a “common” 16-pin Data Link Connector (DLC). Note: Some 1994 and 1995 vehicles have 16-pin connectors but are not OBD II compliant. Only those vehicles with a Vehicle Emissions Control Label stating “OBD II Certified” are OBD II compliant.
LAUNCH TOUCH PRO ELITE 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 TOUCH PRO ELITE 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 TOUCH PRO ELITE 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 TOUCH PRO ELITE 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 TOUCH PRO ELITE User Manual 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. Read and reference this list as needed to aid in the understanding of OBD II systems.
LAUNCH TOUCH PRO ELITE User Manual vehicles and for each monitor in any particular vehicle. Please refer to the vehicle’s factory service manual for specific enabling procedures. Trip - A Trip for a particular Monitor requires that the vehicle is being driven in such a way that all the required “Enabling Criteria” for the Monitor to run and complete its diagnostic testing are met. The “Trip Drive Cycle” for a particular Monitor begins when the ignition key is turned “On.
LAUNCH TOUCH PRO ELITE User Manual 2.6 OBD II 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. Monitor operation is either “Continuous” or “Non-Continuous,” depending on the specific monitor. 2.6.
LAUNCH TOUCH PRO ELITE User Manual 2. Fuel System Monitor 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 TOUCH PRO ELITE 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 TOUCH PRO ELITE 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 TOUCH PRO ELITE 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 TOUCH PRO ELITE 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 TOUCH PRO ELITE User Manual Trip DTCs. When a Type “A” DTC is found on the First Trip, the following events take place: • The computer commands the MIL “On” when the failure is first found. • If the failure causes a severe misfire that may cause damage to the catalytic converter, the MIL “flashes” once per second. The MIL continues to flash as long as the condition exists. If the condition that caused the MIL to flash is no longer present, the MIL will light “steady” On.
