Introduction to On-Board Diagnostics

OBD II (On-Board Diagnostics version 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 USA were
OBD II compliant.

✓ T echn icians now can use the same tool to test any OBD

II compliant vehicle without special adapters. SAE
established guidelines that provide:

❒ A universal connector, called the Data Link Connector

(DLC), with dedicated pin assignments.

❒ A standard location for the Data Link Connector (DLC),

visible under the dash on driver’s side.

❒ A standard list of diagnostic trouble codes (DTCs) used

by all manufacturers.

❒ A standard list of parameter identification (PID) data

used by all manufacturers.

❒ Ability for vehicle systems to record operating conditions

when fault occurs.

❒ Expanded diagnostic capabilities that records a code

whenever a condition occurs that affects vehicle
emissions.

❒ Ability to clear stored codes from vehicles memory with

Tool.

SAE Publications

SAE has published hundreds of pages of text defining a
standard communication protocol that est ablishes hardware,
software, and circuit parameters of OBD II systems.

• SAE publishes recommendations, not laws, but the
Environmental Protection Agency (EPA) and California Air
Resources Board (CARB) made many of SAE’s
recommendations legal requirements.

Diagnostic Trouble Codes (DTCs) and

Data

Read Codes

The Read Codes function allows the AutoScanner® to read
the Diagnostic Trouble Codes (DTCs) and Pending Codes
from the vehicle’s computer modules.

✓ Diagnostic Trouble Codes (D TCs) help determine the cause

of a problem or problems with a vehicle.

✓ Read Codes can be done with the Key On Engine Off

(KOEO) or with the Key On Engine Running (KOER).

✓ “Continuous monitor” and “maturing codes” are other names

for Pending Codes.

✓ If Pending Codes or faults occur a specific number of times

(depending on vehicle), they mature into a DTC and the MIL
lights or blinks.

✓ If a fault does not occur within a certain number of warm-up

cycles (depending on vehicle), the Pending Code or
Diagnostic Trouble Code clears from vehicle’s computer

module.

✓ Pending Code faults, DO NOT automatically indicate a

faulty component or system.

I/M Monitors (Emissions Systems)

The I/M Monitors (Inspection / Maintenance) function is used
to view a SNAPSHOT
System on OBD II vehicles since the Diagnostic Trouble
Codes were cleared.

✓ I/M Monitors is a very useful function. T o guarantee no faults

make sure all monitors are “ok” or “n/a” and no DTC’ s exist.

✓ During normal driving conditions, the vehicle’s computer

scans the emission system. After a specific amount of drive
time (each monitor has specific driving conditions and time
required), the computer’s "monitors" will decide if the
vehicles emission system is working correctly or not as well
as detecting out of range values. When the "monitor’s"
status is:

• "ok" - vehicle was driven enough to complete the monitor.

• "inc" (Incomplete) - vehicle was not driven enough to
complete the monitor.

• "n/a" (Not Applicable) - vehicle does not support that
monitor.

of the operations for the Emission

✓ Some states MAY NOT require all monitors listed to be

Ready to pass the emissions test. Check with state testing
site for exact requirements. All states will fail a vehicle that
has the MIL Light lit at time of test.

✓ Refer to the vehicles service manual for the drive cycle

operation.

✓ Depending on vehicle, disconnecting or a discharged

battery may erase trouble codes and clear monitor status.

is activated (sending a signal to the PCM) when the A/C refrigerant
pressure becomes too low or high.

Actuator:

Actuators such as relays, solenoids, and motors allow the PCM to
control the operation of vehicle systems.

Air Injection Reaction (AIR) System:

An emission control system operated by the PCM. During cold starts,
an air pump injects outside air into the exhaust manifold to help burn hot
exhaust gases. This reduces pollution and speeds warm-up of oxygen
sensors and catalytic converters. After the engine is warm, the air will
either be “dumped” back to the atmosphere (or into the air cleaner
assembly) or sent to the catalytic converter.

systems and Torque Converter Clu tch (TCC) solenoids. See also

TCC.
CAM:

Camshaft Position Sensor. Sends a frequency signal to the PCM in
order to synchronize fuel injector and spark plug firing.

Catalytic Converter:

Designed to reduce exhaust emissions.

CAN:

Controller Area Network.

CARB:

California Air Resources Board. Governing body for emissions control
in California.

CKP REF:

Crankshaft Position Reference.

CKP:
Crankshaft Position. See CPS.

CKT:

Circuit.

x, Sensor x.

A-2

Closed Loop (CL):

A feedback system that uses the O2 Sensor(s) to monitor the results
of combustion. Based on the signal(s) from the O2 sensor(s), the PCM
modifies the air/fuel mixture to maintain optimum performance with
lowest emissions. In closed loop mode, the PCM can “fine tune” control
of a system to achieve an exact result.

CMP:

Camshaft Position Sensor.

CO:

Carbon Monoxide; odorless gas produced by incomplete combustion.

Continuous Memory Codes:
See Pending Codes.

CPS:

Crankshaft Position Sensor. Sends a frequency signal to the PCM. It
is used to reference fuel injector operation and synchronize spark plug
firing on distributorless ignition systems (DIS).

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. V ehicles with OBD II
use a 16-pin connector located in the passenger compartm en t.

Data Stream:

The actual data communications sent from the vehicle’s PCM to the
data connector.

DEPS:

Digital Engine Position Sensor.

Detonation:
See Knock.

DI/DIS:

Direct Ignition/Distributorless Ignition System. A system that produces
the ignition spark without the use of a distributor.

DPFE:

Differential Pressure Feedback – Exhaust Gas Recirculation Sensor

A-3

Drive Cycle:

Vehicle oper ation for a period of time so the systems can be monitored.

DTC:

Diagnostic Trouble Code. An alphanumeric identifier for a fault
condition identified by the On Board Diagnostic System.

Duty Cycle:

A term applied to signals that switch between “on” and “off”. Duty cycle
is the percentage of time the signal is “on” . For example, if the signal
is “on” only one fourth of the time, then the duty cycle is 25%. The PCM
uses duty cycle type signals to maintain precise control of an actuator.

EBCM:

Electronic Brake Control Module.

EBTCM:

Electronic Brake/Traction Control Module.

ECM

Engine Control Module or Electronic Control Module.

ECT:
Engine Coolant Temperature sensor. See CTS.

EEPROM:

Electrically Erasable Programmable Read Only Memory.

EFE:

light are examples of what a MIL is called. A required on-board
indicator to alert the driver of an emission-related malfunction.

Misfire:

Caused by the air fuel ratio being incorrect.

Monitor:

A test performed by the on-board computer to verify proper operation
of emission related systems or components.

MPFI or MFI:

Multi-Port Fuel Injection. MPFI is a fuel injection system using one (or
more) injector(s) for each cylinder . The injectors mounted in the int ake
manifold, and fired in groups rather than individually.

NOx:

Oxides of Nitrogen. The system EGR and Cam Shafts injects exhaust
gases into the intake manifold to reduce these gases at the tailpipe.

O2S:

Oxygen Sensor. Generates a voltage of 0.6 to 1.0 volts when the
exhaust gas is rich (low oxygen content). The volt age changes to 0 .4
volts or less when the exhaust gas is lean (high oxygen content). This
sensor only operates after it reaches a temperature of approxima tely
349ºC (660ºF). O2 sensors are usually found both upstream and
downstream of the catalytic converter. The PCM uses these sensors
to fine tune the air-fuel ratio and to monitor the efficiency of the catalytic
converter. See Bank

OBD II:

On-Board Diagnostics, Second Generation. OBD II is a U.S.
Government-mandated standard requiring all cars and lig ht trucks to
have a common data connector, connector location, communication
protocol, DTCs and code definitions. OBD II first appeared on vehicles
in late 1994, and is required to be present on all cars sold in the US
after January 1, 1996.

ODM:

Output Device Monitor.

A-7

Open Loop (OL):

A control system mode that does not monitor the output to verify if the
desired achieved results. A fuel delivery system will usually operate in
open loop mode during cold engine warm-up because the oxygen
sensors are not yet ready to send a signal. Without the oxygen sensor
signal, the computer cannot check the actual results of combustion.

PCM:

Powertrain Control Module. The “brains” of the engine control system
and transmission control system 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 ECM (Engine Control
Module) is another name used for the PCM.

Pending Codes:

Also referred to as Continuous Memory codes and Maturing
Diagnostic Trouble Codes. Pending Codes may be set by emission
related powertrain components and systems. If the fault does not
occur after a certain number of drive cycles, memory erases the code.

PID:

Parameter Identification. Identifies an address in memory which
contains vehicle operating information.

PNP:

Park/Neutral Position. This is a switch that tells the PCM when the gear
shift lever is in the Park or Neutral position. When in Park or Neutral,
the PCM will operate the engine in an “idle” mode.

PROM:

Programmable Read-Only Memory. The PROM contains
programming information the PCM needs to operate a specific vehicle
model/engine combination.

PSPS:

Power Steering Pressure Switch.

Purge Solenoid:

Controls the flow of fuel vapors from the carbon canister to the intake
manifold. The canister collects vapors evaporating fr om the fuel tank,
preventing them from escaping to the atmosphere and causing
pollution. During warm engine cruise conditions, the PCM energizes
the Purge Solenoid so the trapped vapors are drawn into the engine
and burned.

PWM:

Pulse Width Modulated.

A-8

QDM:

Quad Driver Module.

RAM:

Random Access Memory.

Relay:

An electromechanical device in which connections in one circuit are
switched.

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 and communicates Diagnostic Trou ble Codes,
plus other valuable information for troubleshooting a vehicle through
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. See O2S,

Bank 1, Bank 2.
Sensor:

Any device that reports information to the PCM. The job of the sensor
is to convert a parameter such as engine temperature into an electrical
signal that the PCM can understand.

SFI or SEFI:

Sequential Fuel Injection or Sequential Electronic Fuel Injection . A fuel
injection system that uses one or more injectors for each cylinder. The
injectors are mounted in the intake mani fold and are fired individually.

Solenoid:

A device consisting of an electrical coil which when energized,
produces a magnetic field in a plunger, which is pulled to a central
position. A solenoid may be used as an actuator in a valve or switch.

A-9

STFT:

Short Term Fuel Trim.

STS:

Service Throttle Soon.

TAC:

Throttle Actuator Control.

TBI:

Throttle Body Injection. A fuel injection system having one or more
injectors mounted in a centrally located throttle body, as opposed to
positioning the injectors close to an intake valve port. Central Fuel
Injection (CFI) is another name for TBI on some vehicles.

TCC:

Torque Converter Clutch.

TCM:

Transmission Control Module.

TCS:

Traction Control System for PCM and brakes.

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. Injectors receive fuel as each intake port activates. In each
case, the throttle body is attached to the accelerator pedal.

TPS:

Throttle Position Sensor. Potentiometer-type sensor connected to the
throttle shaft. Its voltage signal output increases as the throttle opens.
The PCM uses this signal to control many systems such as idle speed,
spark advance, fuel delivery, etc.

A-10

Traction Assist:

Assist in traction with brakes only.

TTS:

Transmission Temperature Sensor. A resistance sensor mounted in
the transmission housing in contact with the transmission fluid. It
sends a voltage signal to the PCM indicating the temperature of the
transmission.

VECI:

Vehicle Emission Control Information. A decal located in the engine
compartment containing information about the emission control
systems found on the vehicle. The VECI is the authoritative source for
determining whether a vehicle is OBD

VIN:

Vehicle Identification Number. This is the factory-assigned vehicle
serial number . This number is stamped on a number of locations
throughout the vehicle, but the most prominent location is on top of the
dashboard on the driver’s side, visible from outside the car. The VIN
includes information about the car, including where it was built, body
and engine codes, options, and a sequential build number.

VSS:

Vehicle Speed Sensor. Sends a frequency signal to the PCM. The
frequency increases as the vehicle moves faster to give the PCM
vehicle speed information used to determine shif t points, engine load,
and cruise control functions.

VTD:

Vehicle Theft Deterrent.

Warm-up Cycle:

Warm-up cycle is when the engine coo lant 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 will typically
deliver extra fuel to the engine and de-energize the A/C compressor
at this time for acceleration purposes. The PCM uses a switch or the
Throttle Position Sensor to identify the WOT condition.
