LAUNCH Professional 919X User Manual 1 Overview 1.1 Vehicle Coverage This diagnostic tool is specially designed to work with all OBD II compliant vehicles, including Controller Area Network (CAN). It is required by EPA that all 1996 and newer vehicles (cars and light trucks) sold in the United States must be OBD II compliant and this includes all American, Asian and European vehicles. A small number of 1994 and 1995 model year gasoline vehicles are OBD II compliant.
LAUNCH Professional 919X User Manual 1.2 On-Board Diagnostics (OBD) II 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. OBD II is an early warning system designed to monitor engine, transmission, and emissions control components by performing specific diagnostic test. When a fault condition is detected, the system captures important data and activates the “Check Engine” light.
LAUNCH Professional 919X User Manual management and emissions systems, the PCM also participates in controlling the powertrain (transmission) operation. Most PCMs also have the ability to communicate with other computers on the vehicle (ABS, ride control, body, etc.). DLC -- Data Link Connector. The 16-cavity connector on the vehicle that allows communication between the computer system and the diagnostic tool. MIL -- Malfunction Indicator Lamp.
LAUNCH Professional 919X User Manual different part of the engine or emissions system, the “Trip Drive Cycle” needed for each individual Monitor to run and complete varies. 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 OBD II drive cycle is to force the vehicle to run its onboard diagnostics.
LAUNCH Professional 919X User Manual OBD II Diagnostic Trouble Codes consist of a five-digit alphanumeric code. • The 1st character is a letter (B, C, P or U). It identifies the main system where the fault occurred (Body, Chassis, Powertrain, or Network). • The 2nd character is a numeric digit (0 thru 3). It identifies the type of code (Generic or Manufacturer-Specific). Note: Generic DTCs are codes that are used by all vehicle manufacturers.
LAUNCH Professional 919X User Manual P0201 - Injector circuit malfunction, Cylinder 1 1.5 Location of the Data Link Connector (DLC) The DLC (Data Link Connector or Diagnostic Link Connector) is typically a 16-pin connector where diagnostic code readers interface with the vehicle’s on-board computer.

LAUNCH Professional 919X User Manual 1.6.1 Continuous Monitors Some of the vehicle components or systems are continuously tested by the vehicle’s OBD II system, while others are tested only under specific vehicle operating conditions. The continuously monitored components listed below are always ready: 1. Misfire Monitor This Monitor continuously checks for engine misfires. A misfire occurs when the air-fuel mixture in the cylinder does not ignite.
LAUNCH Professional 919X User Manual The Fuel System Monitor is supported by both “spark ignition” vehicles and “compression ignition” vehicles. The Fuel System Monitor may be a “One-Trip” or “Two-Trip” Monitor, depending on the severity of the problem. 3. Comprehensive Components Monitor (CCM) This Monitor continuously checks all inputs and outputs from sensors, actuators, switches and other devices that provide a signal to the computer.
LAUNCH Professional 919X User Manual 2. O2 Sensor Heater Monitor The Oxygen Sensor Heater Monitor tests the operation of the oxygen sensor’s heater. There are two modes of operation on a computer-controlled vehicle: “open-loop” and “closed-loop.” The vehicle operates in open-loop when the engine is cold, before it reaches normal operating temperature. The vehicle also goes to open-loop mode at other times, such as heavy load and full throttle conditions.
LAUNCH Professional 919X User Manual signal voltage becomes almost the same as the upstream sensor signal. In this case, the monitor fails the test. The Catalyst Monitor is supported by “spark ignition” vehicles only. The Catalyst 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. The computer does not command the MIL on at this time.
LAUNCH Professional 919X User Manual OBD II vehicles are equipped with a fuel Evaporative system (EVAP) that helps prevent fuel vapors from evaporating into the air. The EVAP system carries fumes from the fuel tank to the engine where they are burned during combustion. The EVAP system may consist of a charcoal canister, fuel tank cap, purge solenoid, vent solenoid, flow monitor, leak detector and connecting tubes, lines and hoses.
LAUNCH Professional 919X User Manual on the first trip, the computer temporarily saves this fault in its memory as 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. 1.
LAUNCH Professional 919X User Manual “Freeze Frame” data may or may not be saved at this time depending on manufacturer. The Pending DTC is saved in the computer’s memory for later retrieval. • If the failure is found on the second consecutive trip, the MIL is ordered “On.” “Freeze Frame” data is saved in the computer’s memory. • If the failure is not found on the second Trip, the Pending DTC is erased from the computer’s memory.
