"No data Loaded"

Started up fine this morning.

Remote lock responded with a beep series additional to usual. Thought nothing of it.

Fired her up to shuffle round this afternoon:-

NIT Blank: Dead, Kaput. (I've dealt with loads of disk boot failures, certainly not that, not the usual Raster lines/blank white screen. Just dead, blank, 'unpowered'.
Drivers display: mileage flashing + Message: 'No data Loaded'.

Never seen that before.

Looks as though lost contact on the CAMBUS, or voltage below tolerance.

The usual symptoms of graceful degradation (door microswitch/window detent) all healthy so no indication of low voltage

Fired up and move OK

Performed a battery reset: disconnect for > 5minutes (perhaps should have been longer). Removed dastardly temperamental -ve terminal.
Charged the battery (Healthy - checked by Matt et al a couple of weeks ago) charging directly to terminals:
On CTEK conditioning charge: indicators show decent capacity on start up. Charged for an hour:
Disconnect charger, jiggle/abraded the negative terminal. Re-secured.
Doors locks playing up, microswitches only move window to detent, doesn't unlatch.

Fired up fine.
As anticipated, NIT had reset to default date. Applied correct date/time.
Door locks now responding

Fummf.

She's been sitting out in this appalling wet weather, probably damp temperamentalist

Petulant girl.
Spanked her Ar$e over the top to the Slaughters, Stow and home.
That'll teach you, madame.

Serious, has anyone seen the 'No data Loaded' Message before? I think it said that or something close to that.

What think?

I'll spank her again tomorrow

Thinking about it flashing mileage does mean something but for the life of me I can dig it out of the depths of my noggin. It will come eventually

Yeah there has been a few threads this year about flashing mileage and NIT. Sure they'll pop up if you search

Why is the odometer on the instrument cluster blinking at Key-On?
Every time the ignition key is switched to On, the NBC performs a configuration check of the vehicle. If this check fails, the NBC alarms the user by sending a command for
odometer blinking to the instrument cluster (NQS).
This basically means that the vehicle configuration as stored inside the NBC (Proxi) does not match the actual content of the vehicle as recognised by the NBC.
The following causes can be identified:
• One of the ECU’s is not present in the vehicle.
• One of the ECU’s is disconnected.
• A wiring problem is creating communication problems with one of the ECU’s
• An ECU has been replaced with one of different specifications (example: a NIT Magneti Marelli of hardware version 7.0 has been mistakenly replaced by a NIT Magneti Marelli of hardware version 8.0).
• One of the “Proxed” ECU’s has been replaced and the Proxi alignment procedure has not been performed afterwards.
• An incorrectly configured Proxi file has been uploaded in the NBC.

It came and went so I recon you are in the clear. Yes our Leonardo will do a proxy alignment. It basically loops through all the ECU’s and makes them handshake.

CANBUS! I knew it, wrong bus.
I reckon it was that poncie lot up in Birmingham. All I wanted was a new key programmed. Not going there again. Solihull. Fuff. Messing up me buses.

(Seriously. Probably 'cos she was saturated. Where is the NBC? I thought that was some American News channel)

Catman, Conaero, If you have been following Stephens problems with his 4200 over on ML, I wonder if the Leonardo in proxy alignment mode could get his ECU and immobilizer to shake hands? I don't know, that's why I'm asking.

I'd have thought if it was that 'simple' Jason might have suggested it.? I'll check back in, but if it's been connected to a proper diagnosis system (SD or Leonardo) the lack of 'alignment' would be obvious I'd have thought.

How does the NIT figure in all of this? Does anyone know? If it's a poor connection on the buses this would be prime suspect given the poor cabling and times that the NIT has been pulled?
Just uncomfortable that it came out of the blue

You're right. Fully charged and conditioned, hour and half cruising. Stopped for a pee. Engine start. 10 second blank screen, then the dreaded white screen and cold boot. Should have been a hot start.

Here we go again. I thought that I'd solved all my NIT issues with a bad sector copy.

Anyone know a source of the NIT harness and how much of the dash needs to come out ?

It's horrible behind there.
Pulled the NIT. Dreadful spaghetti tangle.

The main levered connector has a further connector insert, which as best I can tell from Maserati guides contains the B-CAN liners. It was floating about in the cavity. I'd be surprised if pulling the NIT out had snagged and removed it, it's a click fit into the main connector.
Clicked it back after switch cleaner on all male and female connectors.

Seems fine, BUT.

I had this on Mrs C's 147 (cf electrical incompetence threads passim)
Thought it was properly seated. It wasn't

Sounds like a very good possibility

Sounds promising! Love it when you actually find something obviously wrong.
