3. Product description
3.1 Intended use
The OBD 100 reads and displays emissionrelated diagnostic data via the OBD interface
of gasoline and diesel passenger vehicles. It is
also possible to erase or reset trouble codes
and to display additional electronic control unit
information. The diagnostic data can help to
establish the cause of problems in the vehicle.
! The OBD 100 is only to be used with the
vehicle stationary. Use whilst driving is
prohibited.
3.2 Prerequisites

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.
