Introduction to On-Board Diagnostics

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.

2

✓ 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.

❒ A standard location for th e 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 a

fault occurs.

❒ Expanded diag nostic capabi lities that records a code whenever a

condition occurs that affects vehicle emissions.

❒ Ability to clear stored codes from the vehicle’s memory with a

Scan Tool.

SAE Publications

SAE has published hundreds of pages of text defining a standard
communication protocol that establishes 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 recommenda tions legal require ment s.

I/M Readiness

The I/M Readiness (Inspection / Maintenance) function is used to view
a snapshot of the operations for the emission system on OBD II
vehicles.

✓ I/M Readiness is a very useful function. To guarantee no faults exist

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

✓ Refer to the vehicles service manual for the drive cycle operation.

✓ 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 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.

4

✓ Depending on vehicle, disconnecting or a discharged battery may

erase DTCs and clear monitor status.

✓ Monitors may be cleared by:

❒ Erasing codes
❒ Vehicle control modules losing power

✓ I/M Readiness can be done with the KOER or KOEO.

O2 Monitor Test

OBD II regulations require applicable vehicles monito r and test oxygen
(O2) sensors to determine problems related to fuel and emissions. The
O2 Monitor Test allows retrieval of completed O2 sensors monito r test
results.

✓ The O2 Monitor Test is not an on-demand test. O2 sensors are not

tested when selected via the menu. O2 sensors are tested when

engine operating conditions are within specified limits.

✓ If the vehicle communicates using a controller area network (CAN),

O2 monitor tests are not supported by vehicle. A message is

displayed. See “

monitor data.

Diagnostic Monitor Tests” on page 4-25 to see O2

✓ O2 sensors are located before (upstream) and after (downstream)

catalyst(s). Sensors are named (xy) for their position to both cylinder

banks and catalysts.

❒ The O2 sensor for cylinder bank 1 has prefix 1y while O2 sensor

for cylinder bank 2 has prefix 2y.

❒ The O2 sensor up stream of cat alyst (closest to engine) has suffix

x1 while O2 sensor downstream of catalyst has suffix x2. If
vehicle contains more catalysts, O2 sensor downstream of
second catalyst has suffix x3 and O2 sensor downstream of next
catalyst has suffix x4.

❒ For example, O2S21 is upstream O2 sensor for cylinder bank 2.

The following O2 Sensor T ests are available:

1) Rich-to-lean sensor threshold voltage

2) Lean-to-rich sensor threshold voltage

3) Low sensor voltage for switch time

4) High sensor voltage for switch time

5) Rich-to-lean sensor switch time

6) Lean-to-rich sensor switch time

7) Minimum sensor voltage test cycle

8) Maximum sensor voltage test cycle

9) Time between sensor transitions

10) Sensor period

Appendix A – PID Definitions

Global PID Definitions

All global parameter identification (PID) data listed were verified on actual
vehicles to guarantee accuracy. PID definitions were obtained from reliable
sources and are accurate at time of printing. It is possible that some newer
vehicles may contain data different from what is listed. Always refer to vehicle
service manual for manufacturer specific PIDs.

Remember , always refer the ap plicable service manual for det ailed diagnostic
procedures when troubleshooting PID values.

Types of Data Parameters

INPUT: These data parameters are obtained from sensor circuit

outputs. Sensor circuit outputs are inputs to the vehicles
PCM. For example, if oxygen sensor circuit was
generating a 400mV signal, then the code reader would
read O2S (v).40.

OUTPUT: These data parameters are outputs or commands that

come directly from control module(s). For example, the
ignition spark advance is controlled by PCM, on most
vehicles, monitoring this PID shows spark output from
PCM.

CALCULATED These data parameters are calculated after analyzing
VALUE: various inputs to the vehicles control module(s). For

example, the engine load. The PCM calculates this from
sensor inputs and displays in a percentage.

PCM VALUE: Information that is stored in the control module(s) memory

and determined to be useful to service technician. An
example of this is TROUBLE CODE values, the DTC that
caused a freeze frame capture.

NOTE: Seve ral different causes can h ave the same parameter indicatio n. For
information on diagnostics consult applicable service manuals.

NOTE: The Scan Tool only displays the PID’s the vehicle supports.

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.

A/C Pressure Sensor:

Measures air conditioning refrigerant pressur e and sends a voltage signal to the
PCM.

A/C Pressure Switch:

A mechanical switch connected to the A/C refrigerant line. The switch 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 th e
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
