Introduction

The LAUNCH equipment is designed for vehicle diagnostics and troubleshooting. It is compatible with OBD II compliant vehicles.

Vehicle Coverage

The LAUNCH equipment is compatible with most vehicles. To determine if a vehicle is OBD II compliant, look for a label under the hood or near the radiator that designates it as “OBD II Certified”. Additionally, all OBD II- compliant vehicles must have a common 16-pin Data Link Connector (DLC).
Note : Some vehicles with 16-pin connectors may not be OBD II compliant unless they have a Vehicle Emissions Control Label stating “OBD II Certified”.

On-Board Diagnostics (OBD) II
OBD II is a system that monitors and reports vehicle diagnostics. The LAUNCH equipment is specifically designed to work with OBD II systems.

OBD II Definitions
OBD II uses Diagnostic Trouble Codes (DTCs) to identify specific faults or issues in the vehicle. There are three types of DTCs:

1. Current – A DTC is considered current when a fault condition is currently present.
2. Stored – A DTC is stored when a fault condition has occurred in the past.
3. Permanent – A stored DTC that can only be cleared by the OBD II system after repairs are made and a set number of Driving Cycles have been completed.

Example DTC:
P0202 – Injector circuit malfunction, Cylinder 1

Location of the Data Link Connector (DLC)

The DLC is a 16-pin connector where diagnostic code readers interface with the vehicle’s onboard computer. It is typically located 12 inches from the center of the instrument panel, under or around the driver’s side for most vehicles. However, the DLC location may vary for some vehicles with special designs. Please refer to the vehicle’s service manual for the specific DLC location.

Introduction

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. 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. 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.

On-Board Diagnostics (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, which will offer three pieces of such valuable information:

• Whether the Malfunction Indicator Light (MIL) is commanded “on” or “off”;
• Which, if any, Diagnostic Trouble Codes (DTCs) are stored;
• Readiness Monitor status.

OBD II Definitions
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.
EOBD – European On-Board Diagnostics. Essentially the same as OBD II, with the same Data Link Connector and Communication Protocols.
Communication Protocols – Allows different systems and sensors in a vehicle to communicate. There are currently five protocols:

• CAN Bus
• J1850 VPW
• ISO 9141-2
• J1850 PWM
• ISO 14230 KWP

1. PCM — Powertrain Control Module. The PCM is the OBD II accepted term for the vehicle’s “on-board computer.” In addition to controlling the engine 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.).
2. DLC — Data Link Connector. The 16-cavity connector on the vehicle that allows communication between the computer system and the diagnostic tool.
3. MIL — Malfunction Indicator Light. The vehicle’s “Check Engine” warning light that activates when a DTC is stored.
4. DTC — Diagnostic Trouble Code. A code stored in the computer system’s memory, which helps to identify the fault condition that is causing the MIL to activate.
5. Freeze Frame Data — Operating conditions that are stored when a DTC is stored.
6. PID — Parameter Identification Data. Data returned by the vehicle’s control modules to the diagnostic tool.
7. Monitors — Monitors are “diagnostic routines” programmed into the PCM. The PCM utilizes these programs to run diagnostic tests, and to monitor operation of the vehicle’s emissions-related components or systems to ensure they are operating correctly and within the vehicle’s manufacturer specifications.
8. 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. Please refer to the vehicle’s factory service manual for specific enabling procedures.
9. 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. 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 service manual.
10. Fuel Trim (FT) – Feedback adjustments to the base fuel schedule. Short-term fuel trim refers to dynamic or instantaneous adjustments. Long-term fuel trim refers to much more gradual adjustments to the fuel calibration schedule than short-term trim adjustments. These long-term adjustments compensate for vehicle differences and gradual changes that occur over time.

Diagnostic Trouble Codes (DTCs)
A DTC is a five digit alphanumeric identifier for a fault condition identified by the OBD II system. There are three types of DTCs:

1. Pending – when a fault condition is identified during a Drive Cycle, but does not meet enough criteria to activate the MIL.
2. Stored – A DTC is stored when a fault condition has occurred that meets enough criteria to activate the MIL.
3. Permanent – A stored DTC that can only be cleared by the OBD II system, after repairs are made, and a set number of Driving Cycles have been completed.

The first character, a letter, identifies which control system sets the code. The second character, a number, 0-3; other three characters, a hex character, 0-9 or A-F 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:

P0202 – Injector circuit malfunction, Cylinder 1

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. It is usually located 12 inches from the center of the instrument panel, under or around the driver’s side for most vehicles. For some vehicles with special designs, the DLC location may vary.
Refer to the following figure for possible location.

• A- Opel, Volkswagen, Audi
• B- Honda
• C- Volkswagen
• D- Opel, Volkswagen, Citroen
• E- Changan
• F- Hyundai, Daewoo, Kia, Honda, Toyota, Nissan, Mitsubishi, Renault, Opel, BMW, Mercedes-Benz, Mazda, Volkswagen, Audi, GM, Chrysler, Peugeot, Regal, Beijing Jeep, Citroen and other most popular models

If the DLC cannot be found, refer to the vehicle’s service manual for the location.
