  • Page 3: Safety Precautions

    Safety Precautions SAFETY FIRST! SAFETY FIRST! 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. Always read your vehicle's service manual and follow its safety precautions before and during any test or service procedure.

  • Page 8: 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 9 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 10 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 11 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 12 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 13: 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 14 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 15 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 16: 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 17 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 18 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 19 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.
  • Page 20 Onboard Diagnostics OBD2 MONITORS valve to allow engine vacuum to draw the fuel vapors from the canister into the engine where the vapors are burned. The EVAP Monitor checks for proper fuel vapor flow to the engine, and pressurizes the system to test for leaks.
  • Page 21 Onboard Diagnostics OBD2 MONITORS oxygen sensor reacts quickly to any change in oxygen content in the exhaust stream. A faulty oxygen sensor reacts slowly, or its voltage signal is weak or missing. The Oxygen Sensor Monitor is supported by “spark ignition” vehicles only.
  • Page 22 Onboard Diagnostics OBD2 MONITORS NOx Aftertreatment Monitor - NOx aftertreatment is based on a catalytic converter support that has been coated with a special washcoat containing zeolites. NOx Aftertreatment is designed to reduce oxides of nitrogen emitted in the exhaust stream. The zeolite acts as a molecular "sponge"...
  • Page 23 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.

  • Page 25: Using The Scan Tool

    Using the Scan Tool CODE RETRIEVAL PROCEDURE CODE RETRIEVAL PROCEDURE Retrieving and using Diagnostic Trouble Codes (DTCs) for troubleshooting vehicle operation is only one part of an overall diagnostic strategy. Never replace a part based only on the DTC definition. Each DTC has a set of testing procedures, instructions and flow charts that must be followed to confirm the location of the problem.
  • Page 26 Using the Scan Tool CODE RETRIEVAL PROCEDURE 6. The Scan Tool automatically starts a check of the vehicle’s computer to determine which type of communication protocol it is using. When the Scan Tool identifies the computer’s communication protocol, a communication link is established. A PROTOCOL is a set of rules and procedures for regulating data transmission between computers, and between testing equipment and computers.

  • Page 28 Using the Scan Tool CODE RETRIEVAL PROCEDURE The Scan Tool is capable of retrieving and storing up to 32  codes in memory, for immediate or later viewing. 11. Refer to DISPLAY FUNCTIONS on page 3 for a description of display elements.
  • Page 29 Using the Scan Tool CODE RETRIEVAL PROCEDURE Red LED – Indicates there is a  problem with one or more of the vehicle’s systems. The red LED is also used to indicate that DTC(s) are present. In this case, the Malfunction Indicator (Check Engine) lamp on the vehicle’s instrument panel will be illuminated.
