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.
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.
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.
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. As a result, a significant number of vehicles with degraded components were passing Emissions Tests.
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, 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.). Monitor - Monitors are “diagnostic routines” programmed into the PCM.
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.
Onboard Diagnostics DIAGNOSTIC TROUBLE CODES (DTCs) Generic DTCs are codes that are used by all vehicle manufacturers. The standards for generic DTCs, as well as their definitions, are set by the Society of Automotive Engineers (SAE). 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.
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. The diagnostic program saves the code in the computer’s memory.
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). The DTCs are automatically erased if the fault that caused them to be set is not detected again during that period.
Onboard Diagnostics OBD2 MONITORS Non-Continuous Monitors The other twelve Monitors are “non-continuous” Monitors. “Noncontinuous” 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 The following Monitors will be standard beginning in 2010.
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. The program is designed to add or subtract fuel, as needed, up to a certain percent.
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. The computer does not command the MIL on at this time.
Onboard Diagnostics OBD2 MONITORS 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. The computer runs this Monitor once per trip. The EVAP Monitor is supported by “spark ignition” vehicles only. The EVAP 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.
Onboard Diagnostics OBD2 MONITORS 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. The Oxygen Sensor 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.
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" to trap the NO and NO2 molecules in the exhaust stream. In some implementations, injection of a reactant before the aftertreatment purges it.
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.

The Diagnostic Tool returns to the OBD2 DTC screen.
Using the Diagnostic Tool ERASING DIAGNOSTIC TROUBLE CODES (DTCs) The first time the Vehicle ID function is used, it may take several minutes to retrieve the information from the vehicle's computer. 3. When the retrieval process is completed, the vehicle ID information is shown on the Diagnostic Tool’s display. Use the and DOWN buttons, as UP necessary, to view the entire list. 4. When you have finished viewing the retrieved vehicle ID information, press the button to return to exit.
Using the Diagnostic Tool ERASING DIAGNOSTIC TROUBLE CODES (DTCs) Erase DTCs from the computer's memory as follows: When DTCs are erased from the vehicle's computer memory, the I/M Readiness Monitor Status program resets the status of all Monitors to a not run "flashing" condition. To set all of the Monitors to a DONE status, an OBD2 Drive Cycle must be performed. Refer to your vehicle's service manual for information on how to perform an OBD2 Drive Cycle for the vehicle under test.
Using the Diagnostic Tool I/M READINESS TESTING I/M READINESS TESTING I/M is an Inspection and Maintenance program legislated by the Government to meet federal clean-air standards. The program requires that a vehicle be taken periodically to an Emissions Station for an "Emissions Test" or "Smog Check,” where the emissions-related components and systems are inspected and tested for proper operation. Emissions Tests are generally performed once a year, or once every two years.
Using the Diagnostic Tool I/M READINESS TESTING To learn more about Emissions Inspection and Maintenance (I/M) Readiness Monitors, see OBD2 MONITORS on page 22. Each Monitor has a specific function to test and diagnose only its designated emissionsrelated component or system. The names of the Monitors (Oxygen Sensor Monitor, Catalyst Monitor, EGR Monitor, Misfire Monitor, etc.) describe which component or system each Monitor is designed to test and diagnose.
Using the Diagnostic Tool I/M READINESS TESTING Before an Emissions Test (Smog Check) can be performed, your vehicle must meet certain rules, requirements and procedures legislated by the Federal and state (country) governments where you live. 1. In most areas, one of the requirements that must be met before a vehicle is allowed to be Emissions Tested (Smog Checked) is that the vehicle does not have any Diagnostic Trouble Codes present (with the exception of PENDING Diagnostic Trouble Codes). 2.
Using the Diagnostic Tool I/M READINESS TESTING If the illumination of the Yellow LED is being caused by monitors that “have not run” their diagnostic testing, then the issue of the vehicle being ready for an Emissions Test (Smog Check) depends on the emissions regulations and laws of your local area. - Some areas require that all Monitors indicate a "Has Run" status before they allow an Emissions Test (Smog Check) to be performed.
Using the Diagnostic Tool I/M READINESS TESTING On some vehicle models, the computer will store non-emission related DTCs. These DTCs will not command the MIL on since they are not emission related. If the Diagnostic Tool retrieves one of these types of codes, the MIL will not be commanded on, and the Yellow LED on the Diagnostic Tool will be illuminated. In most cases, these types of codes will not prevent the Emissions Test from being performed.
Using the Diagnostic Tool I/M READINESS TESTING 4. When a Monitor's Trip Drive Cycle is performed properly, the Monitor icon on the Diagnostic Tool’s LCD display changes from "flashing" to "solid,” indicating that the Monitor has run and finished its diagnostic testing. 58 If, after the Monitor has run, the MIL on the vehicle's dash is not lit, and no stored or pending codes associated with that particular Monitor are present in the vehicle's computer, the repair was successful.
