Erasing trouble codes

"Erase trouble codes" erases all pending and con-
firmed 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 follow-
ing 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.

Safety information

!
The OBD 150 can only read and recognize
emission-related diagnostic data and faults.
It is not possible to read and display informa-
tion 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 emission-related.
¶
Pay attention to the warnings, instructions
and service procedures of the vehicle manu-
facturer.
¶
The OBD 150 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 150.
¶
Make sure the OBD 150 is always kept in a
safe place.
¶
Never expose the OBD 150 to direct sunlight.
¶
Keep oils, greases, moisture, rainwater and
the like away from the OBD 150. 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 150.
¶
Make sure the OBD 150 and the OBD diag-
nostic connector are dry before connecting
the OBD 150 to the vehicle.
¶
Never connect the OBD 150 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 150 is maintenance-free and has no
exchangeable replacement parts. It is thus
not necessary to open the OBD 150.
¶
Make sure the OBD 150 is not damaged in
any way before connecting the OBD 150 to
the vehicle.
¶
Never route the OBD diagnostic cable over
sharp edges or hot surfaces.
