Hello and thanks for letting me in🙂

My name is Christian, and live in middle of Noway.

I recently bought myself a new truck, 05’cummins.
I'm pretty happy with the truck, but there are some small issues that came with the purchase.

Oiltemp gauge, coolant gauge and speedometer doesn’t work at all. Oil and coolant gauges are standing sky high permanently, but the speedometer is completely dead.

I took the instrument cluster test, but couldn't find any answers that seems right. I’ll add some pictures and hope someony could help me.

 

The first set is the actual code. The second set is the number of key cycles since the code set.

A4 - Ignition Run/Start circuit rationality <- I have no clue what that means.
AE ACM messages not received.

00 end of codes.

I have no idea how to interpret those.
