  • Page 3: Introduction

    Introduction WHAT IS OBD? WHAT IS OBD? The Scan Tool is designed to work on all OBD2 compliant vehicles. All 1996 and newer vehicles (cars, light trucks and SUVs) sold in the United States are OBD2 compliant. One of the most exciting improvements in the automobile industry was the addition of on- board diagnostics (OBD) on vehicles, or in more basic terms, the computer that activates the...

  • Page 4: You Can Do It

    You Can Do It! EASY TO USE - EASY TO VIEW - EASY TO DEFINE Easy To Use ..Connect the Scan Tool to the vehicle’s test connector. Turn the ignition key "On.” The Scan Tool will automatically link to the vehicle’s computer.

  • Page 5: Safety Precautions

    Safety Precautions SAFETY FIRST! SAFETY FIRST! To avoid personal injury, instrument damage and/or damage to your vehicle; do not use the Scan Tool before reading this manual. This manual describes common test procedures used by experienced service technicians. Many test procedures require precautions to avoid accidents that can result in personal injury, and/or damage to your vehicle or test equipment.
  • Page 6 Safety Precautions SAFETY FIRST! To prevent damage to the on-board computer when taking vehicle electrical measurements, always use a digital multimeter with at least 10 MegOhms of impedance. Fuel and battery vapors are highly flammable. To prevent an explosion, keep all sparks, heated items and open flames away from the battery and fuel / fuel vapors.

  • Page 13: Onboard Diagnostics

    Onboard Diagnostics COMPUTER ENGINE CONTROLS COMPUTER ENGINE CONTROLS The Introduction of Electronic Engine Controls Electronic Computer Control Systems make it possible for vehicle manufacturers to comply with the tougher emissions and fuel efficiency standards mandated by State and Federal Governments. As a result of increased air pollution (smog) in large cities, such as Los Angeles, the California Air Resources Board (CARB) and the Environmental Protection Agency (EPA)
  • Page 14 Onboard Diagnostics COMPUTER ENGINE CONTROLS The Basic Engine Computer Control System The Computer Control System consists of an on-board computer and several related control devices (sensors, switches, and actuators). The on-board computer is the heart of the Computer Control System. The computer contains several programs with preset reference values for air/fuel ratio, spark or ignition timing, injector pulse width, engine speed, etc.
  • Page 15 Onboard Diagnostics COMPUTER ENGINE CONTROLS Vehicle operating conditions are constantly changing. The computer continuously makes adjustments or corrections (especially to the air/fuel mixture and spark timing) to keep all the engine systems operating within the preset reference values. On-Board Diagnostics - First Generation (OBD1) 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.
  • Page 16 Onboard Diagnostics COMPUTER ENGINE CONTROLS Because OBD1 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.
  • Page 17 Onboard Diagnostics COMPUTER ENGINE CONTROLS Powertrain Control Module (PCM) - The PCM is the OBD2 accepted term for the vehicle’s “on-board computer.” In addition to controlling the engine management and emissions systems, 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.).

  • Page 18: Diagnostic Trouble Codes (Dtcs)

    Onboard Diagnostics DIAGNOSTIC TROUBLE CODES (DTCs) OBD2 Drive Cycle - An OBD2 Drive Cycle is an extended set of driving procedures that takes into consideration the various types of driving conditions encountered in real life. These conditions may include starting the vehicle when it is cold, driving the vehicle at a steady speed (cruising), accelerating, etc.
  • Page 19 Onboard Diagnostics DIAGNOSTIC TROUBLE CODES (DTCs) Manufacturer-Specific DTCs are codes that are controlled by the vehicle manufacturers. The Federal Government does not require vehicle manufacturers to go beyond the standardized generic DTCs in order to comply with the new OBD2 emissions standards.
  • Page 20 Onboard Diagnostics DIAGNOSTIC TROUBLE CODES (DTCs) DTCs and MIL Status When the vehicle’s on-board computer detects a failure in an emissions-related component or system, the computer’s internal diagnostic program assigns a diagnostic trouble code (DTC) that points to the system (and subsystem) where the fault was found.

  • Page 21: Obd2 Monitors

    Onboard Diagnostics OBD2 MONITORS If the conditions that caused the MIL to light are no longer present for the next three trips in a row, the computer automatically turns the MIL “Off” if no other emissions-related faults are present. However, the DTCs remain in the computer’s memory as a history code for 40 warm-up cycles (80 warm-up cycles for fuel and misfire faults).
  • Page 22 Onboard Diagnostics OBD2 MONITORS Non-Continuous Monitors The other twelve Monitors are “non-continuous” Monitors. “Non- continuous” Monitors perform and complete their testing once per trip. The “non-continuous” Monitors are: Oxygen Sensor Monitor Oxygen Sensor Heater Monitor Catalyst Monitor Heated Catalyst Monitor EGR System Monitor EVAP System Monitor Secondary Air System Monitor...
  • Page 23 Onboard Diagnostics OBD2 MONITORS 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.
  • Page 24 Onboard Diagnostics OBD2 MONITORS the downstream sensor 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.

NOx Aftertreatment is designed to reduce oxides of nitrogen emitted in the exhaust stream. The zeolite acts as a molecular "sponge"...
  • Page 28 Onboard Diagnostics OBD2 MONITORS PM Filter Monitor - The particulate matter (PM) filter removes particulate matter from the exhaust stream by filtration. The filter has a honeycomb structure similar to a catalyst substrate, but with the channels blocked at alternate ends. This forces the exhaust gas to flow through the walls between the channels, filtering the particulate matter out.
