Dash codes 01 and 03, no start

[ChrisG]

2006 Breva 1100. I just completed fuel filter replacement, oil pressure switch, valves, inner plugs, etc.  Started right up, ran for about 30 seconds, and then quit. Will not start now.  Turns over fine, has spark, but no smell of fuel.  I can go into the diagnostics on the dash, no ecu errors, but two dash errors: “DSB 01: Immobilizer fault, key code read but not recognized or key code not read” and “DSB 03, Immobilizer fault: Antenna broken (open circuit).”

I will see what GuzziDiag tells me tomorrow.

Any thoughts?

Is immobilizer antenna failure common?

Thanks, Chris

Chris,

I would think that if the two errors are active, then your key wouldn't be recognised and you wouldn't be able to start the bike without entering your personal code.  Have you tried deleting them? 

Then I'd reckon that the filter has come adrift. Have you opened the fuel cap and seen or heard any swirling fuel?

I had an antenna fault on my 05 B11 a couple of weeks back which resulted in it coming home on a trailer 'cos I had forgotten the security code 

On mine it was the 2 pin connector between the antenna and the loom.

One of the female spade terminals had failed so that it didn't make contact with the male terminal, so looked to the dash like an antenna open circuit failure

Replaced the female terminal and normal service was resumed

Thanks Mackers and Tris

GuzziDiag found errors PO351 and PO352, which relate to the coils, red herrings I think.  (The immobilizer errors may be just distractions too – at least I hope so.)

I turned on the fuel pump with GuzziDiag and heard swishing of gas in the tank, which, I think, points to a broken line or other leak (or as Mackers suggested, “the fuel pump has come adrift” – a more elegant description). 

I’ll pull the fuel pump and take a look.

Problem solved.

Sure enough, fuel line had slipped off the pump in the tank.  I snugged everything up and it started right up. I’ll balance the TBs etc. and be off. 
It was the simplest of things, as it often is.  I think the immobilizer codes threw me off.  Those my have been generated when I was reattaching the battery – I fumble around quite a bit, powering up and down many times rapidly and making a bunch of intermittent connections.

Thanks again Mackers and Tris for your help.

On the some models with fuel pump in the tank, the short length of tubing between the filter and the pump (I think it's this one) was made of some material not designed to be immersed in fuel.  What would happen is the tubing would soften and the pressure would blow it off the spigot.

Happened to me once.  Not hard to fix, but not something you want to do on the side of the road.

I wrote my code on the base of my seat - and the service code.
