Hello all. I wonder if anybody could try and help me with a little dash problem i have please?
I have just bought (a couple of weeks ago) a 2006 Stilo 1.9JTD. The car has quite obviously been sat a long time and has not been used (at least a year i would guess). It has a dash problem that i am trying to sort out but it does not seem to have the same issue as others i have seen on here.
Basically the speedo, rev counter and temp gauge don't work. The fuel gauge appears to be working as it was at the top of the red bit and has dropped a little. The fuel low light is on along with the temp red light, glow plug light, handbrake warning light, ABS light and the yellow triangle in the middle of the dash. All the other lights were also on but one by one i have fixed them as there were a lot of bad connections on fuses and earth leads.
I have plugged a scan tool in and the fault it give is U1700 which appears to be a dash communication error.
My question is could the car have lost communication between the dash and the ECU due to being sat for so long (looks like it's had a new battery so i suspect the old one died)? If this is the case i am wondering if getting it proxi aligned might solve the issues i am still having? Everything else works as it should including seat belt and door warning lights etc.
Any help would be gratefully recieved.
Thanks,
Mick

UPDATE

I have today received my FiatECUScan software and cable kit. I have deleted the errors possible (i appear to have a Can Comm fault that keeps coming back) and i have carried out the proxi alignment. This has put out all the warning lights that were previously on. My fuel gauge appears to work and the fuel light is on (gauge is in the red but not sure how much fuel is in it) but the other gauges/dials don't work. Here is a copy of the log file following proxi alignment:

I'm guessing these nodes won't complete their end of line programming due to a faulty dashboard but i would like some further confirmation before i spend anymore money!!

Has anybody got any ideas?

Thanks in advance.

Mick

Further Update

I have today driven the car and can confirm that the speedo still does not work but the fuel gauge does!!

I have an oil light that won't go out, a temp light that won't go out and an engine management light on. I suspect the engine light is due to the CAN Communication fault that is logged in the memory and won't erase.

Is it common when the dash cluster goes faulty to lose the speedo, rev counter and temp gauge but the fuel gauge continues to work?

If it is the instrument cluster can anybody suggest a good place to get it repaired please? I have tried to find a replacement but i can't find anything with a similar part number. My part number for the cluster is VP4FCF-10849-KBA.

Thanks,

Mick

The number you've quoted is just a moulding number for the plastic casing. The Fiat part number should be at the top left corner of the paper label. It will probably be an 8 digit number starting with 467.

Ohh cheers. In that case the part number is 51772815.

Can anybody help with that number please? Or can you recommend a good repairer?

Thanks,

Mick

I've still had no joy with this!! Has anybody had similar dash issues? If I was certain the dash was at fault I'd send it for repair but is there anything else it could be? Are there any other common issues?
Thanks,
Mick

Hi, I've had the same problems with all the Gauges freezing and all the warning lights coming on and staying on, sometimes whilst driving but mostly just after starting the engine and especially if the low fuel light is on at the time, sometimes it will rectify itself after 5 mins but not always. All this started just after a recall by fiat, for spring retainers to be fitted, when the car was 3 months out of warranty but Fiat didn't want to know about the the dash fault unless I paid megabucks to have it fixed! I have had the car from new and it is now 9 yrs old by the way.
I have invested in the paid up registered version of FiatECUscan, an ELM lead , VAGCom lead and 3 short adaptor leads, (red, yellow & green) that connect to the car for various functions.
I have tried everything I can to stop this fault occurring to no avail. the only way I have found of restoring the dash to normal, albeit for a short time , is to disconnect the battery and leave it for around 5 mins before reconnecting, then all is ok for a while. Its annoying but there seems no way to stop it happening. so if anyone has any Idea what can be done it would be most greatly appreciated .

i can repair your instrument clusters for a fair price but you would have to send them to the Netherlands....
repair on day of arrival, return shipping next day.
Further info by PM.

Update:
I have spent all day on the car today and i'm still no nearer
I have replaced the instrument cluster, cleaned all the earth connections, removed and cleaned every fuse and i even tried swapping a body control module (but it would not start due to the immobiliser). Still no better!!
I keep getting the same fault code which is: U1700 - CAN: Body Computer conn fault (1) no signal
Everything else now works fine except the speedo, rev counter and temp gauge. If you use the Fiat ECU Scan software and connect to the body it says the engine temp is -40 and will not read an engine speed or car speed. If you go in through engine it reads the engine speed correctly (on the laptop, not the dash) and the coolant temp. Also if you connect to the ABS you can get a speed reading through the laptop.


Can anybody please help me? I'm on the verge of scrapping the car now as it's driving me crazy.

get a copy of the can wiring from the Elearn cd and check all can lines, especially in the neighbourhood of the bodycomputer....

My CD with elearn has arrived this morning so I will have a look.
I also bought another Stilo last week to use for spares. Would I be right if thinking that if I swapped the body computer and engine ecu and held the key close to the ignition barrel that it should start and not trigger the immobilizer?

Surely if you suspect the dash is faulty it would make more sense to swap the dash, not the body and engine ECU's?

I have already replaced the instrument cluster and it is just the same. The fault I appear to have is no signal from the body computer to the engine ecu.

Sorry, I'm nursing a hangover caused by yesterdays birthday celebrations.

Just read it again.

As you've already swopped the Body ECU and it made no difference it seems to me the problem must be the CAN line between the engine and body ECU's.
You need to check the CAN wiring.

I did swap the body computer but due to the immobiliser I could start the car to check it. I couldn't find any way to programme the key with the Fiat ECU Scan software.
Have you got any advice on checking the CAN wiring please?
Thanks,
Mick

Have you tried connecting FES to the cluster to see what error codes are stored there?

Yes but there are no faults in the cluster. The body computer error is logged in the engine ecu.

try to locate the beginning and end of each wire of the CAN schematics, measure and for close to 0 ohm resistance between both ends of each wire and check for 60 ohms between the two can lines (with connectors attached to all nodes as there are two of them with a 120 ohm resistor inside to terminate both ends of the CAN bus - two 120 ohms resistors parrallel = 60 ohms....)
to find out which node has a 120 ohm termination resistor inside unplug each node seperately from the can bus whilst measuring both can lines - when the resistance jumps from 60 to 120 ohm you detached a node with termination resistor.
these kind of jobs usually take some time to find the cause of the fault.

Ohh that's doesn't sound straight forward!! I will hopefully get chance over the weekend to have a look.
Thank you for all your help.

I think i might have a look at this tomorrow as it's driving me crazy!! I do however have a couple of questions please?

1. What does a node look like? Is this going to be visible in the wiring or is it an integral part of the instrument cluster and body control module?
2. If i get 60 ohms across the two CAN lines and 0 ohms down each wire do i need to go further with the wiring checks?
3. I have looked on elearn and pins 3 and 4 from the instrument cluster look like they go direct to the body control module. Is this correct?
4. I know a fault on the CAN lines would cause the issue with my rev counter and speedo not working but would this also stop the temp gauge from working and the oil light from going out?

Sorry for all the questions but i need to understand a little further as to how the system works.

Thanks,

Mick
