Fejlsøgningen viser fabrikationsfejlen.

Because both nouns are in the definite singular form, meaning the ... in English.

• fejlsøgning = troubleshooting

• fejlsøgningen = the troubleshooting

• fabrikationsfejl = manufacturing defect / production flaw
• fabrikationsfejlen = the manufacturing defect / the production flaw

In Danish, the definite article is often added to the end of the noun instead of being a separate word.

In Danish, the is usually expressed as a suffix attached to the noun.

So instead of a separate word like in English, Danish often does this:

• en fejl = a mistake / an error
• fejlen = the mistake / the error

That is why you see:

• Fejlsøgningen rather than a separate word for the troubleshooting
• fabrikationsfejlen rather than a separate word for the manufacturing defect

A separate definite word such as den is mainly used when there is an adjective:

• fejlen = the error
• den alvorlige fejl = the serious error

The dictionary forms are:

• fejlsøgning = troubleshooting
• vise = to show
• fabrikationsfejl = manufacturing defect / production flaw

In the sentence:

• Fejlsøgningen is the definite singular form of fejlsøgning
• viser is the present tense of vise
• fabrikationsfejlen is the definite singular form of fabrikationsfejl

Yes. Viser is the present tense form of at vise.

• at vise = to show
• viser = shows / is showing

So Fejlsøgningen viser fabrikationsfejlen uses a normal present-tense verb.

This is the standard Danish main-clause order:

subject + verb + object

• Fejlsøgningen = subject
• viser = verb
• fabrikationsfejlen = object

So it works very much like English here:

• The troubleshooting shows the manufacturing defect

Danish is a V2 language, which means the finite verb usually comes in the second position in main clauses. In this sentence, the subject comes first, so the verb naturally comes right after it.

Fejlsøgning usually means troubleshooting, fault-finding, or diagnostic checking, depending on context.

It is a compound noun:

• fejl = error, fault
• søgning = searching

So the literal idea is something like searching for faults.

In technical contexts, fejlsøgning is very common for diagnosing a problem in a machine, system, device, or process.

Fabrikationsfejl means a manufacturing defect, production defect, or factory flaw.

It is also a compound noun:

• fabrikation = manufacture / production
• fejl = error, fault, defect

Together, it refers to a defect that happened during manufacturing.

That s is a very common linking element in Danish compound words.

Here the compound is built from:

• fabrikation
• s
• fejl

So:

• fabrikation + s + fejl = fabrikationsfejl

This linking s does not usually change the meaning. It mainly helps join the parts of the compound in a natural way. English learners often notice this because English compounds do not use this pattern in the same way.

Because Danish, like German, normally writes compound nouns as one word.

So Danish prefers:

• fejlsøgning
• fabrikationsfejl

rather than separate words.

This is very important in Danish spelling. What English writes as manufacturing defect, Danish often writes as a single compound noun.

In this sentence, word order tells you that:

• Fejlsøgningen is the subject
• fabrikationsfejlen is the object

Danish does not mark subjects and objects with different noun endings the way some other languages do. Instead, it relies heavily on normal word order.

So in a plain statement like this, the first noun before the verb is typically the subject, and the noun after the verb is typically the object.

It would become:

En fejlsøgning viser en fabrikationsfejl.

That means A troubleshooting process shows a manufacturing defect or A diagnostic check reveals a manufacturing defect, depending on context.

Compare:

• fejlsøgning = troubleshooting

• fejlsøgningen = the troubleshooting

• fabrikationsfejl = a manufacturing defect / manufacturing defect
• fabrikationsfejlen = the manufacturing defect

A rough guide is:

fejl-søg-ning-en

Some helpful points:

• fejl sounds roughly like file but not exactly
• søg contains the Danish ø, which does not exist in English
• -ningen has a soft, unstressed ending

A rough English-friendly approximation might be:

file-SUHG-ning-en

But that is only approximate. The hardest parts for English speakers are usually:

• ej in fejl
• ø in søg
• the smooth unstressed endings

Yes, depending on context. Viser literally means shows, but in technical or analytical contexts it can often be translated more naturally as:

• shows
• indicates
• reveals
• demonstrates

So if this sentence appears in a technical report, English might naturally say:

• The troubleshooting reveals the manufacturing defect
• The diagnostic process indicates the manufacturing defect

The best English translation depends on the situation, even though the Danish verb is simply viser.
