Principles of Operation
For Principles of Operation on the electronic
accelerator control system
REFER to: Acceleration Control (31
0-02A,
Diagnosis and Testing).
European On-Board Diagnostics (EOBD)
EOBD is a diagnostic system integrated into the
powertrain control module (PCM). This system
continuously monitors vehicle emission
components. The system includes a malfunction
indicator lamp (MIL) which indicates when there is
a concern that can affect emissions or the system
malfunctions. Data stored within the module DTC
memory can be accessed using a generic scan
tool or WDS.
EOBD is mandated within European Union
regulations from the year 2000 for passenger
vehicles with petrol engines and from 2003 onwards for passenger vehicles with diesel
engines.
EOBD Functions:
Establishes when and how emissions control
faults must be indicated.
Actuates emission control malfunction indicator
lamp (MIL) and fault memory.
Indicates operating conditions in which the
concern occurred (freeze frame data).
Standardized output of operating data such as
engine speed, engine coolant temperature etc.
Standardized names and abbreviations for
components and systems.
Standardized
DTCs for all manufacturers.
Standardized communication with the diagnostic
equipment.
Standardized 16-pin data link connector (DLC)
in area of the instrument panel.
Concern display must be possible using a
generic scan tool.
EOBD consists of the following elements:
Warm-up Cycle C'
The warm-up cycle is an operation that consists of
key on, engine start and a coolant temperature
increase of
22"C, exceeding 71 OC on completion.
Drive Cycle
A drive cycle commences when the engine is
started (cold or warm) and ends when the engine
is switched off.
Trip
A trip begins when the engine is started and is
complete when all the EOBD monitors have
completed a self-test. This may take place over a
number of drive cycles. On diesel variants, the
information gathered from one drive cycle is not
carried over to a subsequent cycle or cycles.
When a concern has been rectified, particularly
after electronic engine control components have
been changed, the DTC memory, which is part of
the EEPROM must be cleared of all trouble codes.
When the DTC memory has been cleared, the code
.
PI000 (known as the readiness code) is set in the
PCM memory, which indicates that since the
EEPROM has been cleared, not all of the
monitoring systems have completed their tests.
PI000 can only be cleared by carrying out a trip,
which includes driving the vehicle under variable
conditions of speed, load and time so that all of the
monitors are completed. As
PI000 will not
illuminate the MIL it is not necessary to carry out
the trip before returning the vehicle to the customer.
Freeze Frame Data
When a concern is detected, various data is stored
depending on application including:
Diagnostic trouble code.
Vehicle speed.
Engine coolant temperature.
Engine speed.
Engine load.
Mixture formation trim value (trim value for
engine wear) (All except vehicles with diesel
engine).
State of oxygen sensor control (open and closed
loop) (All except vehicles with diesel engine).
Distance covered since the concern was first
registered.
