4. All you need to know
about OBD
4.1 What are OBD, OBD II, OBD-2
and EOBD
OBD (on-board diagnosis) means that
R Emission-related components and systems
are monitored by the vehicle whilst driving
R Any malfunctions are recorded and indicated
by a warning lamp (MIL)
R This information can be read by a diagnostic
tester
i A further purpose of OBD is to protect
vulnerable components such as catalytic
converters.
In these operating instructions, OBD is always
used to refer to the standard OBD-2 (OBD II).
OBD-2 has been obligatory in the USA for all
new vehicles since 1st January 1996. In the EU,
OBD-2 was introduced for new vehicles with
gasoline engine in January 2001 with the EURO3 standard and for diesel vehicles in January
2004. EOBD is the abbreviation for European
on-board diagnosis based on OBD-2.
The OBD diagnostic system is integrated into the
electronic control unit and constantly monitors
defined emission-related components in the
vehicle. The malfunction indicator light (MIL)
informs the driver of OBD faults reported by the
electronic control unit.
A minimum of five monitoring systems are
provided:
R Emission-related components
R Missing combustion
R Fuel system
R Upstream and downstream Lambda sensors
R Catalytic converter efficiency
R Exhaust gas recirculation
R Secondary air system
The following are monitored once per drive
cycle:
R Lambda sensor function
R Catalytic converter function
i Speed, temperature and Lambda sensor
values can also be read out by way of the
OBD diagnostic socket.
4.2 Is my vehicle provided with OBD
In the EU, OBD-2 was introduced for new vehicles
with gasoline engine in January 2001 with the
EURO-3 standard and for diesel vehicles in
January 2003.
i Vehicles manufactured before these dates
may however also be provided with OBD.
4.3 Where is the OBD diagnostic socket located
The OBD diagnostic socket is usually situated
in the driver's footwell in the area of the center
console or in the glove compartment.
i The installation location can also be looked
up in the owner's manual of the vehicle
concerned or found in the internet.
4.4 Why and when does the malfunction indicator light (MIL)
come on
The malfunction indicator light must come on
briefly when switching on the ignition. The
malfunction indicator light must go out at the
latest when the engine is started. The MIL status
(malfunction indicator light "On" or "Off") is
read from the vehicle electronic control unit.
If the vehicle has detected an emission-related
fault, the status is set to "faulty". It is then no
longer possible to pass the exhaust emission
test. In such cases the malfunction indicator
light is permanently lit to show the driver that
the vehicle should be taken to a workshop.
The following are permanently monitored:
R Missing combustion
R Fuel system (injection times)
R Circuits for emission-related components

4.5 What are trouble codes
The OBD trouble codes (DTC) are defined in
SAE J2012 and ISO 15031-6. Manufacturerspecific trouble codes can be defined by vehicle
manufacturers.
A trouble code is a 5-position code made up of
a letter and four digits. A distinction is made
between standard trouble codes which may
occur with all vehicle makes and manufacturerspecific trouble codes specified by vehicle
manufacturers for certain vehicle models.
i A plain language text outlining the cause of
the problem can be assigned to each trouble
code.
4.5.1 Trouble code structure
i The structure of the trouble codes is shown in
the following table. This information facilitates
trouble-shooting in situations for which no
trouble code description is provided.
Trouble codes are 5-position codes.

4.5.2 Stored trouble codes
Stored trouble codes (DTC) are trouble codes
which have been stored in the electronic control
unit (ECU). The description of the trouble
code and the number of the electronic control
unit with the designation of its origin are also
displayed.
i If a trouble code has been set which causes
the malfunction indicator light (MIL) to come
on, the electronic control unit stores the
current values of the sensors at the time at
which the fault occurred.
4.5.3 Pending code (Pnd)
The first time a fault occurs this is stored
as a pending code in the fault memory. If a
pending code is confirmed in the second drive
cycle, it becomes a confirmed code. A pending
code stored in the electronic control unit is
automatically erased after 40 drive cycles
if the prevailing operating conditions were
the same as when the trouble code was set.
Otherwise the pending code is erased after
80 engine cycles. Such trouble codes report
those faults which have occurred during a drive
cycle but which were not sufficient to cause a
trouble code to be stored, i.e. not causing the
malfunction indicator light to come on.
4.5.4 Confirmed code (Cnf)
If a pending code is confirmed in the second
drive cycle, it becomes a confirmed code and
the malfunction indicator light comes on.
4.5.5 Permanent code (Prm)
Permanent codes are a special form of confirmed
codes. Permanent codes have only been set by
vehicles since 2010, which means that they are
not supported by all vehicles.
i Permanent codes cannot be erased with a
diagnostic tester or by disconnecting the
battery voltage. The problem must have been
rectified and must not have occurred again for
the trouble code to be automatically deleted
from the fault memory by the electronic control
unit.
569624 Rev "A" 2013-12-19
|
i The presence of a permanent code will cause
the vehicle to fail an Inspection or exhaust
emission test.
Robert Bosch GmbH
All you need to know about OBD | OBD 100 | 7 en
4.5.6 Erasing trouble codes
"Erase trouble codes" erases all pending and
confirmed codes from the fault memory.
! Before erasing trouble codes it must be
remembered that this procedure also resets
all the freeze frame data and the status of the
on-board monitoring (Readiness codes). As
a result, exhaust emission testing performed
directly after erasing the trouble codes may not
be passed by reading out the OBD diagnostic
data, as the vehicle has not yet completed its
internal tests. Additional testing (exhaust gas
measurement or sensor testing) is required in
such cases.
Erasing the trouble codes also deletes the
following information stored in the electronic
control unit:
R Number of trouble codes
R Freeze frame data
R Status of system monitoring tests
R Engine running time (in minutes) with activated
malfunction indicator light since trouble codes
were last erased.
5. Operation
5.1 Safety information
! The OBD 100 can only read and recognize
emission-related diagnostic data and
faults. It is not possible to read and display
information or faults relating to airbags, the
braking system, steering or other important
vehicle functions. The vehicle is therefore
to be taken to a workshop in the event of
any vehicle reports which are not emissionrelated.
¶ Pay attention to the warnings, instructions
and service procedures of the vehicle
manufacturer.
¶ The OBD 100 is not intended for use by
anyone (including children) with physical,
sensory or mental disabilities or without
the necessary experience and/or knowledge
unless they are supervised by a person
responsible for their safety or have received
instructions from this person on how to use
the OBD 100.
¶ Make sure the OBD 100 is always kept in a
safe place.
¶ Never expose the OBD 100 to direct sunlight.
¶ Keep oils, greases, moisture, rainwater and
the like away from the OBD 100. Avoid all
contact with water or other liquids. Water
could cause a short circuit and damage both
the vehicle to be tested and the OBD 100.
¶ Make sure the OBD 100 and the OBD
diagnostic connector are dry before
connecting the OBD 100 to the vehicle.
¶ Never connect the OBD 100 to a vehicle with
wet hands.
¶ Secure the vehicle to stop it rolling away.
¶ Prior to vehicle testing make sure the
transmission is set to PARK (automatic) or
NEUTRAL (manual) and that the handbrake
is applied.
¶ Unless otherwise stated, the ignition is
always to be set to OFF on connecting and
disconnecting electrical components.
¶ The OBD 100 is maintenance-free and has no
exchangeable replacement parts. It is thus
not necessary to open the OBD 100.
¶ Make sure the OBD 100 is not damaged in
any way before connecting the OBD 100 to
the vehicle.

5.4.2 Erasing trouble codes
! The function "Erase trouble codes" is not to
be performed until the systems have been
fully checked and the trouble codes written
down.
! Do not erase the trouble codes before
establishing whether repair is necessary.
Failure to perform essential repairs
could prove costly and dangerous. If the
malfunction indicator light (MIL) is reset
without the underlying problem having
been rectified, the indicator light will come
on again. If the underlying problem is of a
serious nature, further trouble codes may
be set or the fault may be aggravated if
appropriate action is not taken. It is not
sufficient to just erase the trouble codes and
reset the warning light. The underlying fault
must be rectified.
! Before erasing trouble codes it must be
remembered that this procedure also erases
all the freeze frame data and the status of
the on-board monitoring (status mask). As a
result, exhaust emission testing performed
immediately after erasing may not be
successful if the vehicle has not completed
its internal tests by then.
i Once the vehicle has been serviced any
trouble codes stored can be erased if so
desired. If a trouble code appears again, this
means that the problem has not yet been
rectified or other faults have occurred.
i All trouble codes are displayed with the
corresponding icon.
i Scroll through trouble codes using READ or

Cnf Confirmed code
If a pending code is confirmed in the second
drive cycle, it becomes a confirmed code and
the malfunction indicator light (MIL) comes on.
DTC Diagnostic trouble code
A trouble code is a 5-position code made up of
a letter and four digits. A distinction is made
between standard trouble codes which may
occur with all vehicle makes and manufacturerspecific trouble codes specified by vehicle
manufacturers for certain vehicle models.
Aplain language text outlining the cause of the
problem can be assigned to each trouble code.
ECU Electronic control unit
EOBD European On-Board diagnosis
EOBD is not an official term but is often used to
refer to OBD-2 in conjunction with EU vehicles.
For further information refer to Section 4.1.
Drive cycle
A drive cycle commences on starting the engine
(warm or cold) and ends on switching off the
engine.
Freeze frame data (FFD)
The following data (freeze frame data) are
stored in connection with the first pending
code:
R Vehicle speed
R Coolant temperature
R Intake manifold pressure
R Engine load
R Mixture formation adaptation value
R Lambda control status (control loop)
R Time since trouble first recorded
The data represent a sort of snapshot of the
prevailing operating and ambient conditions at
the moment in time at which the trouble was
detected. A freeze frame data set remains stored
in the memory even if another emission-related
trouble code is stored (this does not however
apply to trouble codes resulting from misfiring
or faults in the fuel system). Freeze frame data
stored for a trouble code arising from misfiring
or a fuel system fault overwrite all previously
stored data and cannot be overwritten
themselves.
I/M monitors
The Readiness code is used in OBD to refer
to the testing of emission-related functions.
Since the introduction of OBD-2 all electrical
components have been continuously checked for
proper operation. In addition, complete systems
(e.g. exhaust gas recirculation) are checked
by way of diagnostic routines which are not
constantly active. The Readiness code is set as
a means of checking whether these diagnostic
routines have been performed.
The Readiness code gives an indication of
whether a diagnosis result has been supplied
for all individual systems since the fault memory
was last erased or the electronic control unit
was replaced.
The following are permanently monitored:
R Missing combustion
R Fuel system (injection times)
R Circuits for emission-related components
The following are monitored once per drive
cycle:
R Lambda sensor function
R Catalytic converter function
If the functions of systems and components
are tied to certain operating conditions, these
are only checked on passing the corresponding
operating points (speed, load or temperature
thresholds).
569624 Rev "A" 2013-12-19

i The Readiness code was introduced as a
means of revealing manipulation. It makes
it possible to see whether the fault memory
was erased by disconnecting the battery for
example.
Robert Bosch GmbH
Glossary | OBD 100 | 15 en
MIL Malfunction indicator light
The malfunction indicator light (also called
malfunction lamp or engine warning lamp) comes
on:
R If the ignition key is in position II (bulb check
function).
R If a fault occurs during the electronic control
unit self-test.
R If an emission-related fault occurs in two
consecutive drive cycles.
R If a fault (misfiring) occurs which results
in cylinder deactivation, i.e. for catalytic
converter protection (the MIL flashes in this
case).
i The malfunction indicator light goes out
automatically in the fourth drive cycle if
the fault has no longer occurred in three
consecutive drive cycles.
OBD On-Board diagnosis
In these operating instructions, OBD is always
used to refer to the standard OBD-2. In the EU,
OBD-2 (EOBD) was introduced for new vehicles
with gasoline engine in January 2001 with the
EURO-3 standard and for diesel passenger
vehicles in January 2003.
i Vehicles marketed before these dates may
however also be provided with OBD.
Prm Permanent code
Permanent codes are a special form of
confirmed codes. Permanent codes were first
set by vehicles around 2010, which means that
they are not supported by all vehicles. Whereas
confirmed codes can be erased by way of the
diagnostic tester, this is not possible in the
case of permanent codes. Permanent codes are
erased by the vehicle if the electronic control
unit has decided that the fault no longer exists.
Readiness code Refer to I/M monitors
VIN Vehicle identification number
The vehicle identification number is the serial
number assigned to a vehicle at the factory.
The vehicle identification number is marked
on the driver side of the dashboard and can
be seen from outside the vehicle. The vehicle
identification number contains information
on the vehicle, as well as the body and engine
code numbers for example. Provided that the
electronic control unit has not been replaced,
the vehicle identification number displayed in
the OBD 100 must coincide with the vehicle
identification number of the vehicle. Matching
numbers ensure that the correct diagnostic data
are being displayed. It is advisable to consult a
workshop if the vehicle identification numbers
do not match.
OBD-2 Refer to OBD
PID Parameter identification
Status information, actual values and electronic
control unit values calculated by the system are
output by way of PID (refer also to Section 9).
Pnd Pending code
The first time a fault occurs this is stored as a
pending code in the fault memory. This fault
appeared during a drive cycle but was not
sufficient to set the MIL status to ON.
