Odd dash error set

[ITSec]

The other day the Norge threw a rather odd set of errors while showing SERVICE on the dash. I was out picking up a few things, and when I came out to start the bike I got the same antenna problem I get from time to time (prompts for code). When I turned off the key, waited, shifted the forks slightly and restarted, it started as normal - and then quickly threw a full dash SERVICE message but continued to run normally.

I waited a moment, turned off the bike, then turned it on again - and immediately got the service notice. I headed home and parked it till I could figure it out. When I went today to check, the SERVICE notice would no longer come up, the dash was normal, and I was able to go and read the saved dashboard errors. These were:

Immobilizer fault: key code read but not recognized            DSB 01
Immobilizer fault: Antenna broken (open or short-circuit)    DSB 03
immobilizer fault: internal controller fault                              DSB 04
Fuel sensor fault                                                                   DSB 05
Air temperature sensor fault                                                 DSB 06
Oil sensor fault                                                                    DSB 07

No errors on the other diagnostics, and oddly no 02 or 08 errors (which might indicate a dash connector problem more definitely).

Any ideas?

Dash connectors would be where I'd start too, along with battery earth strap behind the starter motor.  It's unlikely to be all the faults indicated.

I agree.  Those last three codes probably have something in common upstream -- a connector, fuse, section of harness, ground, . .  . .

You say you've had symptoms of the first three codes in the past.  Unless they share the commonality of the last three, they're a separate issue.

Do you have a wire map?

Actually, I didn't have those codes previously - what I had was the not unusual occasional failure of the system to recognize the key on the first try, often associated with a slightly bad connection to the antenna. The only codes I've ever seen previously are the same ones we all do - the 07 and 08 that indicate an oil pressure sensor failure.

If I only got the first three, I'd decide the antenna (or its wiring) have finally failed for real - but they came at the same time as the last three which don't share much in the wiring with the components for the last three errors.

The first point they all have in common is the battery (and its ground), and the second is the dash itself (and its connector). If it doesn't repeat for a while, I'll have trouble figuring this out.
