MIL Malfunction indicator light
The malfunction indicator light (also called mal-
function 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 auto-
matically 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 vehi-
cles in January 2003.
i
Vehicles marketed before these dates may
however also be provided with OBD.
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).
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 suffi-
cient to set the MIL status to ON.

Permanent code
Permanent codes are a special form of con-
firmed codes. Permanent codes were first set
by vehicles around 2010, which means that they
are not supported by all vehicles. Whereas con-
firmed codes can be erased by way of the diag-
nostic 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 identifica-
tion 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 identifi-
cation number displayed in the OBD 150 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 vehi-
cle identification numbers do not match.
