Getting Started OBD II On-board diagnostics version II (OBD II) is a system that the Society of Automotive Engineers (SAE) developed to standardize automotive electronic diagnosis. Beginning in 1996, most new vehicles sold in the United States were fully OBD II compliant. ✓ Technicians can now use the same tool to test any OBD II compliant vehicle without special adapters. SAE established guidelines that provide: ❒ A universal connector, called the DLC, with dedicated pin ❒ ❒ ❒ ❒ ❒ ❒ assignments.
Getting Started SAE Publications 2 SAE has published hundreds of pages of text defining a standard communication protocol that establishes hardware, software, and circuit parameters of OBD II systems. Unfortunately, vehicle manufacturers have different interpretations of this standard communications protocol. As a result, the generic OBD II communications scheme varies, depending on the vehicle.
Getting Started Data Link Connector (DLC) The data link connector (DLC) allows the Scan Tool to communicate with the vehicle’s computer(s). Beginning in 1996, vehicles sold in the United States use the J1962 (OBD II) DLC, a term taken from a physical and electrical specification number assigned by the SAE (J1962). The DLC should be located under the dashboard on the driver’s side of the vehicle.
Getting Started OBD II Diagnostic Trouble Codes (DTCs) ✓ J2012 and ISO 15031-6 are standards for all DTCs, established by the SAE, International Organization for Standardization (ISO) and other governing bodies. ❒ Codes and definitions assigned by these specifications are 2 ✓ known as Generic OBD II codes. ❒ OBD II requires compliance to these standards for all cars, light trucks, APVs, MPVs, and SUVs sold in the United States.

Glossary Appendix B – Glossary A/C: Air Conditioner A/D: Analog to Digital A/F: Air/Fuel ratio. The proportion of air and fuel delivered to the cylinder for combustion. For example, an A/F ratio of 14:1 denotes 14 times as much air as fuel in the mixture. Ideally the A/F ratio is 14.7:1. ABS: Anti-lock Brake System A/C Clutch Relay: The PCM uses this relay to energize the A/C clutch, turning the A/C compressor on or off.
Glossary BBV: Brake Boost Vacuum (Sensor) BCM: Body Control Module Boost Control Solenoid: A solenoid that is energized by the PCM, in order to control turbo/supercharger boost pressure. Brake Switch Signal: An input signal to the PCM indicating that the brake pedal is being pressed. This signal is typically used to disengage Cruise Control systems and Torque Converter Clutch (TCC) solenoids. See also TCC. CAM: Camshaft Position Sensor.
Glossary CTS: Coolant Temperature Sensor. A resistance sensor that sends a voltage signal to the PCM indicating the temperature of the coolant. This signal tells the PCM whether the engine is cold or warm. CVRTD: Continuous Variable Real Time Damping D/R: Drive/Reverse Data Link Connector (DLC): Connector providing access and/or control of the vehicle information, operating conditions, and diagnostic information. Vehicles with OBD II use a 16-pin connector located in the passenger compartment.
Glossary EFI: Electronic Fuel Injection. Any system where a computer controls fuel delivery to the engine by using fuel injectors. EGR: Exhaust Gas Recirculation. The PCM uses the EGR system to recirculate exhaust gases back into the intake manifold to reduce emissions. EGR is used only during warm engine cruise conditions. EOP: Engine Oil Pressure (Switch) EOT Engine Oil Temperature (Sensor) EPA: Environmental Protection Agency. ESC: Electronic Spark Control.
Glossary IAC: Idle Air Control. A device mounted on the throttle body which adjusts the amount of air bypassing a closed throttle so that the PCM can control idle speed. IAT: Intake Air Temperature (Sensor) ICM: Ignition Control Module. IMRC: Intake Manifold Runner Control IPC: Instrument Panel Cluster ISC: Idle Speed Control. A small electric motor mounted on the throttle body and controlled by the PCM. The PCM can control idle speed by commanding the ISC to adjust its position.
Glossary MAP: Manifold Absolute Pressure (sensor). Measures intake manifold vacuum or pressure and sends a frequency or voltage signal (depending on sensor type) to the PCM. This gives the PCM information on engine load for control of fuel delivery, spark advance, and EGR flow. MAT: Manifold Air Temperature (sensor). A resistance sensor in the intake manifold that sends a voltage signal to the PCM indicating the temperature of the incoming air. The PCM uses this signal for fuel delivery calculations.
Glossary PCM: Powertrain Control Module. The brains of the engine and transmission control systems housed in a metal box with a number of sensors and actuators connected via a wiring harness. Its job is to control fuel delivery, idle speed, spark advance timing, and emission systems. The PCM receives information from sensors, then energizes various actuators to control the engine. The PCM is also known as the ECM (Engine Control Module).
Glossary ROM: Read-Only Memory. Permanent programming information stored inside the PCM, containing the information the PCM needs to operate a specific vehicle model/engine combination. RPM: Revolutions Per Minute SAE: Society of Automotive Engineers. Scan Tool: A device that interfaces with and communicates information on a data link. SDM: Sensing and Diagnostic Module Sensor x: A standard term used to identify the location of oxygen sensors. Sensor 1 is located upstream of the catalytic converter.
Glossary TDC: Top Dead Center. When a piston is at its uppermost position in the cylinder. TFP: Transmission Fluid Pressure TFT: Transmission Fluid Temperature (Sensor) Throttle Body: A device which performs the same function as a carburetor in a fuel injection system. On a throttle body injection (TBI) system, the throttle body is both the air door and the location of the fuel injectors. On port fuel injection systems (PFI, MPFI, SFI, etc.), the throttle body is simply an air door.
Glossary Warm-up Cycle: Warm-up cycle is when the engine coolant temperature rises at least 40 degrees above that at engine start up. WOT: Wide-Open Throttle. The vehicle operating condition brought about when the throttle is completely (or nearly) open. The PCM typically delivers extra fuel to the engine and de-energizs the A/C compressor at this time for acceleration purposes. The PCM uses a switch or the TPS to identify the WOT condition.
