The DTC memory was erased

If the voltage supply has been disconnected

.
During driving operation in various load
conditions, exhaust relevant tests are performed
by the control module within a "short trip" and
readiness code is generated on its own. In this
case, however, concluding control possibilities
are not available, meaning that it will not be
indicated whether all positions of the readiness
code are set to "0."
