Re: stop start not working

red-van-man/k333fer,

do you guys have links to a wiring diag for the S-S system? anyone else?

my 2013 fiorino with dualogic is coming to end of its 2 yr warranty (i live in turkey) in mid april. start stop pretty much hasnt worked from day 1 so i thought i would try to push the issue and get them to change my battery before the warr stopped. from my reviews in this forum, the inputs to the S-S system are batt voltage via the IBS sensor atop the battery (which from what ive read takes inputs from even door switches and the amount of fuel in the tank!), the state of the DPF being regen'd, and others.

i do admit that, as a retiree, i dont drive the car everyday. one time i didnt drive it for a week and 1/2 and the battery actually required a jump start which i did. i think that previously, K333fer said that jumpers cant kill the IBS and i didnt know this at the time. even so, how do you disconnect (disco) it? i dont see a wire going from the IBS to the battery to disco?

the turkish fiat dealer did (another) top-off charge on the battery...like the first time i took it in for this problem. which didnt fix it. in turkey, fiat HQ's actually remotes into the dealership diagnostic equipment and the factory engineers have a look for themselves before any parts are replaced under warranty. they said there's nothing wrong with this battery, were not replacing it and here's a printout of the battery report. they said your problem is you dont drive the car enough in stop-start style traffic...the ACIDIC levels (or lack thereof) inside the battery enable/disable the S-S system. they said the people who drive this car are usually commercial merchants doing maybe 100 stop-starts per day. this changes the acidic levels in the battery and makes the system WORK/NOT WORK. they said you, on the other hand, drive maybe 15 mi 1-way to your wife's mothers home via the high speed highway loop and while this charges the battery, it's not enough to enable S-S system (acidically internal to the battery).

some factors may have been lost in the translation but they seemed vehement in insisting it was not a battery voltage problem but a battery internal acidity level wasnt being maintained.

the turk dealers DO REPLACE parts under warr. last time i took it in for the S-S problem, another problem came up just 2 days before: a loud "clunk" could be heard/felt when going into reverse...only reverse no other gears. i mentioned this in passing to service rep because it only happened in last days and i hadnt done any research on it yet. turned out they straight-away replaced the "clutch/clutch servo" unit assembly inside the tranny and this involved removing the tranny. didnt sound $ cheap for them or time cheap. they just did it. the main problem i was there for was the 2nd S-S issue, but they performed the tranny repair pronto.

but they simply wont replace this battery so maybe they're right. i still would like to see a S-S wiring diagram? anyone have? thanks.

on a side note: my S-S sytem wont even turn off. upon turning the system "off" with the button and obtaining the amber light, the system still works. however, i get around it by pressing only lightly on the brake pedal at stop lights...not hard. the system will not engage.

i think the system is just poorly designed and with too many superfluous inputs but id like to see a wiring diagram if possible, and, to hear any other inputs from the experts here.

Re: stop start not working

You may have just hit the nail on the head by saying you have to push on the brake pedal lightly , the pedal switch isn't a on off switch as we know it its a position switch hence when you brake proper hard the hazards come on so it may not be set right I know if the vag ones aren't set right they will make the stability system play up

Sorry, completely wrong though.

The brake switch is an on/off switch, and has no control over the hazzard flashing system under heavy breaking. Its the ABS system / body computer which controls that and activates when breaking speed is in excess of 7m/s(squared).

This is why they won't come on when hammering the brake when stationary, or below about 20MPH.

Indeed - I second that. Far too much technical bosh that's unnecessary.

Latest thing I've discovered (the fault that led me to be stranded in the outside lane of a dual carriageway in rush-hour) is an overheating issue related to the transmission.

If you're in slow traffic (or me, maybe not you?) and crawling so that the infernal S-S sytem isn't coming on after the first annoying 'death', the engine is running and the car is creeping a bit at a time as you do in slow queues. Then you notice the warning triangle comes on, It tells you the Hill Hold has ceased working, the Start Stiop is now dead and the there's another one I've forgotten. probably Anti-Slip/Traction thingy.
You delete them with the Menu button - then the transmission warning comes on (flashing little red gearbox) and you can no longer go up over gear #3 . You curse of course, but nothing can be done. Don't be tempted turn off to reboot as it will not restart but give some non-understandable warning saying you have to refer to the Owners Manual (which will be at home) and there's some delayed start procedure to follow. WHAT use is that when you're out in the sticks or wherever??

I got round this the second time (not turning off) by keeping driving once the queue was easing and moving and after about 150 yards I was able to get into 4th and 5th gear, some cooling had taken place. Another time it happened I wound the fan up to max speed and opened the windows and that cooled it down.

Yet another occasion when it happened, (which is quite amazing for the situation) I was going down a long Derbyshire hill behind a very large gravel lorry (rigid not artic) who was too large for the road and was travelling at under 30 most of the way. The Dualogic box of course wouldn't let me go into 5th and that 1.5 miles or so of downhill was all done in 3rd and 4th. Then I got the warnings and max of 3rd gear as it was getting too hot again.

What stupid designer decided to put all this sh*te so-called technology into a car as simple as a Qubo should be? These guys take most of the fun or enjoyment out of motoring with their extras and add-ons and stupid under-the-bonnet things we only discover we have, when something decides to fail. Is it to cause frustration or generate revenue for the dealers? It certainly does the former!

Grrr. Anyone else suffered this overheat thing?

Re: stop start not working

R-V-M,

thanks. your issues may be beyond start-stop system issues. like you, i have a 2013 dualogic tranny.

in 2014 (exactly 1 year after bought the car) i changed the oil ahead of manf standards using fiat brand oil filter and the fiat equivalent castrol C4 spec oil, the equivalent of fiat's C4 brand (and probably superior because it has the oil molecule technology that lets oil molecules stick to engine surfaces during "stop-start" conditions within high traffic). oil in turkey is VERY expensive and the dealer is likewise FURTHER expensive and i know how to change oil and know about minding oil specs for motors. this was the first car i bought new...after initial breakin phase i wanted that factory dose of new engine oil "outta there quickley" and the filter as well. so i changed it. @ 3800 miles

"(the fault that led me to be stranded in the outside lane of a dual carriageway in rush-hour) is an overheating issue related to the transmission"

ive never had any related such faults and as i recall, were using the same castrol C4 spec oil because i read this before in your posts.

can trannies in fact overheat? i thought engines did...but do trannies? if the tranny had a heat sensor in it and it went off, but the engine (which has ALOT more sensors than the tranny) was normal in its temps indications, this seems your tranny is low on oil maybe? how can a tranny overheat without its brother the engine overheating? unless some unit in the tranny is defective?

your post:
"I got round this the second time (not turning off) by keeping driving once the queue was easing and moving and after about 150 yards I was able to get into 4th and 5th gear, some cooling had taken place. Another time it happened I wound the fan up to max speed and opened the windows and that cooled it down"

and this one:
"Yet another occasion when it happened, (which is quite amazing for the situation) I was going down a long Derbyshire hill behind a very large gravel lorry (rigid not artic) who was too large for the road and was travelling at under 30 most of the way. The Dualogic box of course wouldn't let me go into 5th and that 1.5 miles or so of downhill was all done in 3rd and 4th. Then I got the warnings and max of 3rd gear as it was getting too hot again"

this leads me to believe that your dualogic clutch control box may be defective as mine was (read above in my post for this free (otherwise expensive repair by dealership). if your unit is having problems shifting gears (errr...restricting oil flow thru dualogic shifting solenoids restricting oil flow = extra heat!) then the tranny is going to heat up, tripping heat sensors (if present in tranny?) and shut down other systems, like stop start.

when i brought my car in to the dealership for the 2nd stop start incident, i was trying to get them to replace the battery under warranty because i had read here that the IBS sensor was/could be (K333per) main culprit in S-S issues.

in this same 2nd visit, the turk service dept immediately replaced the "clutch servo assembly" device when i complained of loud noises going into only reverse gear.

could it be your "clutch servo assembly" unit is also defective? inside the clutch/tranny? and that this might be causing the overheat and triggering the other malfunctions?

A bit harsh pal, i've been doing my job 35 years and still learning, sometimes the obvious smacks you in the face and you still don't see it.
I think the way to go is take on board what people say, and look at things from a different perspective.
no disrespect meant

Re: stop start not working

I'm with 2668 GRIFFIN, Mines a 2009, no fancy stuff like the newer ones, thank heavens. I'm afraid, I would not buy a new car now, because of all the stuff I don't want. So my last new car, current Qube, is here to stay...........for a long, long time.

Yep Ditto here
I'm going to get a respray and recon the engine and gear box instead of getting another van, which i was going to do next year.

Re: stop start not working

Hi members.

As someone that does very little milage (2000 pa) and what milage I do is based on very short 6 mile round trips picking the wife up from work, I was very surprised just how long the EFB battery fitted to our Qubo lasted without charging from an external charger.

But like all good things, they come to an end at some point. Stop/start stopped working one day no warning, turned it off then back on again, still nothing.

Having read up on S/S technology the Qubo has what they call a BMS (battery management system) this will if detected turn off the S/S function, also items like air/con function can be reduced. other things that may affect this is if the weather is too cold or too hot.

I have a local garage, I say local, I can see the garage opposite my window the other side of the road, glow/plug warning light was coming on from time to time, a knock from the front nearside strut on rebound, so it was time for some TLC new plugs/struts/top mountain bushes.

I purchased a NOCO G2700 charger armed with the above information, charged the battery over the weekend, all now good on the S/S first time I came to a stop, S/S cut in.

I hope this info helps anyone in the future if you need it.

Phillip.

Re: stop start not working

I use a AA Smart Charger, got it from Amazon at a good price. Works great on keeping my battery well topped up, even though my Qubo is too old for stop/start, it can sit on the drive for 2/3 days & nights. Just monitors the battery and keeps its ready to go.........I used the supplied simple connection kit so only takes moments to connect/disconnect. Great tools...........Cheers Qube O.
