  • Page 19: Code Retrieval Procedure

    Using Code Reader 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 20 Using Code Reader CODE RETRIEVAL PROCEDURE If the Code Reader does not turn on automatically when connected to the vehicle, it indicates that there is no power at the vehicle's DLC. Check your fuse panel and replace any burned-out fuses. If replacing the fuse(s) does not correct the problem, consult your vehicle's repair manual to locate the proper computer (PCM) fuse/circuit.
  • Page 21 Using Code Reader CODE RETRIEVAL PROCEDURE Green LED - Indicates that all engine systems are "OK" and running normally. All monitors on the vehicle are active and are performing their diagnostic testing, and no trouble codes are present. A zero will show on Code Reader’s LCD display for further confirmation.

  • Page 24 Using Code Reader I/M READINESS TESTING On OBD 2 systems, the I/M program is enhanced by requiring vehicles to meet stricter test standards. One of the tests instituted by the Federal Government is called I/M 240. On I/M 240, the vehicle under test is driven under different speeds and load conditions on a dynamometer for 240 seconds, while the vehicle's emissions are measured.
  • Page 25 Using Code Reader I/M READINESS TESTING To learn more about Emissions Inspection and Maintenance (I/M) Readiness Monitors, see OBD 2 MONITORS on page 38. Each Monitor has a specific function to test and diagnose only its designated emissions- related 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...
  • Page 26 Using Code Reader I/M READINESS TESTING status. This information is very important since different areas of the state/country have different emissions laws and regulations concerning Monitor Run/Not Run status. 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.
  • Page 27 Using Code Reader I/M READINESS TESTING 2. YELLOW LED - Determine from the Code Retrieval Procedure (page 17) which of the two possible conditions is causing the yellow LED to light. If a "PENDING" Diagnostic Trouble Code is causing the yellow LED to light, it is possible that the vehicle will be allowed to be tested for emissions and certified.
  • Page 28 Using Code Reader I/M READINESS TESTING Repair the vehicle yourself. If you are going to perform the repairs yourself, proceed by reading the vehicle service manual and following all its procedures and recommendations.

  • Page 32 Learning More 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 33 Learning More COMPUTER ENGINE CONTROLS The computer compares the values received from these sensors with its preset reference values, and makes corrective actions as needed so that the sensor values always match the preset reference values for the current driving condition. The computer makes adjustments by commanding other devices such as the fuel injectors, idle air control, EGR valve or Ignition Module to perform these actions.
  • Page 34 Learning More COMPUTER ENGINE CONTROLS On-Board Diagnostics - Second Generation (OBD 2) In addition to performing all the functions of the OBD 1 System, the The OBD 2 System is an OBD 2 System has been enhanced enhancement of the with new Diagnostic Programs.
  • Page 35 Learning More COMPUTER ENGINE CONTROLS The Main Objectives of the OBD 2 System are: To detect degraded and/or failed emissions-related components or systems that could cause tailpipe emissions to exceed by 1.5 times the Federal Test Procedure (FTP) standard. To expand emissions-related system monitoring. This includes a set of computer run diagnostics called Monitors.
  • Page 36 Learning More COMPUTER ENGINE CONTROLS Enabling Criteria - Each Monitor is designed to test and monitor the operation of a specific part of the vehicle's emissions system (EGR system, oxygen sensor, catalytic converter, etc.). A specific set of "conditions" or "driving procedures" must be met before the computer can command a Monitor to run tests on its related system.

  • Page 42 Learning More OBD 2 MONITORS Misfire Monitor - This Monitor continuously checks for engine misfires. A misfire occurs when the air-fuel mixture in the cylinder does not ignite. The misfire Monitor uses changes in crankshaft speed to sense an engine misfire. When a cylinder misfires, it no longer contributes to the speed of the engine, and engine speed decreases each time the affected cylinder(s) misfire.
  • Page 43 Learning More OBD 2 MONITORS Heated Catalyst Monitor - Operation of the "heated" catalytic converter is similar to the catalytic converter. The main difference is that a heater is added to bring the catalytic converter to its operating temperature more quickly. This helps reduce emissions by reducing the converter's down time when the engine is cold.
  • Page 44 Learning More OBD 2 MONITORS Air Conditioning (A/C) Monitor - The A/C Monitor senses leaks in air conditioning systems that utilize R-12 refrigerant. Vehicle manufacturers have been given two options: 1. Use R-12 refrigerant in their A/C systems, and integrate an A/C Monitor in the OBD 2 systems of these vehicles to detect for refrigerant leaks;...
  • Page 45 Learning More OBD 2 MONITORS The oxygen sensor must reach a temperature of at least 600- 650°F, and the engine must reach normal operating temperature, for the computer to enter into closed-loop operation. The oxygen sensor only functions when the computer is in closed-loop. A properly operating oxygen sensor reacts quickly to any change in oxygen content in the exhaust stream.
