vehicle (K1)
Maintenance failure - condition of road
(K2)
Inadequate quality control – vehicle
(K3)

SPECIFIC Genotypes (with
definitions)
Tyres (I1.1)
One or many tyres fail to maintain
pressure, thereby not performing as
expected.
Steering (I1.2)
The steering system fails in, one way
or another, and does not perform as
expected.
Brake system (I1.3)
The brake system fails, in one way or
another, and does not perform as
expected.
Lighting (I1.4)
The lighting fails, in one way or
another, and does not perform as
expected.
Other (I1.5)
Deficient navigation system (I2.1)
Information is not available due to
software problems or other such
problems.
Other (I2.2)
Examples for SPECIFIC Genotypes
A tyre explodes.
The steering column breaks.
A brake-disc is overheated.
The left front headlight is not working.
The performance of the system slows
down. This can be critical for
command and control, in particular.
GENERAL Genotypes (with
definitions)
Equipment failure (I1)
Some piece of equipment brakes or
the performance of a system does not
behave as expected/intended.
Software fault (I2)
The software is performing slower
than expected or not at all.
