D4 Light Flashing on YRV Turbo

Forum: 

Wife starts car this morning and gets to end of road and realises its stuck in 1st gear and there's no number on the display. After a restart, all was ok and has been all day. I checked the battery voltage earlier, 12.02 volts adfter being sat for 2 hours, and 14.4 volts whilst engine running. During cranking, the voltage drops to 10v. Went out earlier and it was fine.

So what do you think lol?

Some owners have had this

Some owners have had this happen although never happened to me.

It only ever seems to do this then go away again, never permanent failure. Maybe its damp, temperature, fluid condition or any combination ???

Im curios to know if anything records on diagnostics when this happens.

This has indeed come up in a previous posting last year. Usually around winter some owners have reported the flashing 'D' light. Wasn't the fix to have a new car battery?
Don't forget the Auto-box also has a type of Electronics that talks to the ECU, so as Dave says could be reporting a fault somewhere due to damp on the sensor.

Fix was a new batery apparrently Smile

Dave you and I had replied to this one as well Wink

I wasnt sure if anything was

I wasnt sure if anything was definately the cause, i just recalled it was a glitch that seemed to happen on cold damp starts. My thoughts were more on thrashed gearboxes and/or worn fluid etc.

Regards recorded fault codes etc i was thinking more on the lines of the in depth diagnostics like the dealership DS21 and DS2 would show up. I have a DS21 but not worked out how to use it yet Help
It definately reads alot more than just codes. When the Daihatsu Area Service manager used his on my car it showed even when my battery was disconnected and reconnected etc

bad battery connection or very cold...

I've had this happen 3 times (all within the first few months of owning the car)... twice when it was sub-zero temps and I drove off after a few seconds without warming the car up. Drove a few hundred metres and realised the D4 was flashing and no changing gears, then pulled over, let her idle till up to temperature, switched off and started again and the flashing D4 went off... only other time, the negative terminal was loose on the battery. Took me a while to figure it out, but the moment I tightened it up, no more hassles.

Thanks for the replies guys.

Thanks for the replies guys. In relation to any fault code, it appears this member found no code with his Scangauge 2...............

Quote:

"I also got a scan gauge 2 and no fault code when gear box goes funny? Went funny again this morning but did notice the car didn't sound so good turning over so maybe battery on the way out will look in to the battery problem and get back. Cheers daihatsu-stu"

So I guess, from this, no code is flagged up.

From what I've read I'm thinking voltage problems. Might accidently leave my lights on for a bit and then try starting it to see what happens. Incidently, the wife tells me she started it and immediately drove off when it went wonky whereas we both normally let it idle for 30 secs or so before setting off. Time will tell I guess Smile

---------------------------------------------------

Yes but the Scangauge II plugs into the ECU

Wayne, Don't forget that the Gearbox has it's own Electronics and may not tell the ECU the problem. Therefore it makes perfect sense that the Scanguage 2 wouldn't pick up any error codes. Be interesting to see what you get with the battery, just out of a matter of interest how long has the battery been in the car for?

Not sure how long the battery

Yes, I'm sure you're right about the ECU not getting the any form of error code. Not sure how long the battery has been on there, it's a Banner non maintenance free thing and I have checked that there's water covering the plates etc. Will source a beefy battery at some point. Went to Halfrauds for last one for previous YRV as I have a discount card, and had a few probs finding one that fitted and one where the terminals were round the right way round etc!
The car has been fine since it first faulted earlier in week.

Curently have a 40Ah VARTA

Curently have a 40Ah VARTA ASIA battery in my car, chances are you may have a lower ampage type battery and more prone to lower voltage when it gets warn out. Considering that the last owner may not be car and tech savvy I would point the finger to the battery, unless you can hook up something like a volt metre to the battery to measure what the voltage is when the car has been left standing.

Will check voltage in

Will check voltage in morning. I checked it the day the light flashed after the car was standing for 4 hours and iirc it was 12.02v, 14v whilst running and 10v when cranking.

Incidently, really enjoying the car. Found that in steershift mode, flat out in 1st and second is remarkable. Yes it does do 80 units per hour (lol) in 2nd gear as I discovered earlier Blum 3 Can honestly say I don't really thrash it that much and it gets treated really well; always warm up/warm down etc etc. Had a few comments on its condition etc and a few people asking what the hell it is. Got to admit I like driving something a little different, especially when you blow the chavs away off the lights.............;-)

---------------------------------------------------
2004 Yellow YRV Turbo

Oh yes good old 2nd gear......................

Your battery sounds about fine from what you are saying, mine is around that as well. The only thing I can think of is that someone mentioned about the connections not being tight enough to the battery. The one I have is a Maintenance free one. And yes these batteries are a bit of challenege to source, as you have found out Halfrauds don't stock our battery at the best of times, as the one we have the Japanese type terminals (I.e smaller than the european ones), then again our cars were imported from Japan and set-up for the Euro-market Smile
If you want another battery then the place I found on the web to get them is from here:

Did it again earlier >:( Car

Did it again earlier. Car had been sat for four hours this time, not overnight. I did notice that when selecting Reverse it really clonked in hard when the D4 light is flashing. Once restarted, all was ok again and when selecting reverse it was nice and smooth. Didn't, however, check the battery voltage - wish I had now. I hope it is sa voltage issue and nothing more sinister otherwise it will have to go.............:(

Hi Wayne. Ummm... maybe

Hi Wayne. Ummm... maybe worth swapping the battery or to try first take the battery out and put it on a full charge using a battery charger to see. I take it you have enough transmission fluid?
Sorry to hear you are having these issues, be sorry to see a new owner have to leave so soon due the issues you're facing Sad

I don't currently have a charger but I will have a poke around at the weekend to make sure everything is clean and tight. A few members have spoke about "the sensor" on here, are they reffering to anything inparticular on the gearbox? There is a plug/loom on the front of the gearbox, does this unplug do you know? I wonder if there's damp or something there.
I will only get shot of it if it persistently gives me grief! I was in a mood earlier, you won't get shot of me that easily. I love the car and I just hope it loves me and behaves itself!

Had a poke around earlier and

Had a poke around earlier and found the negative terminal omn the battery a little loose. Removed both terminals and cleaned them and the battery posts. Also cleaned the earth connection to the inner wing. Upon starting it up, the speedo went up to 70 mph then both the speedo and rev counter went to zero and then up to normal again. Must have been some kind of initialisation thing after the battery is disconnected? Weird. Here's hoping the loose neg term is the cause.

Hope it solves the issue for you Smile Not disconnected the battery on mine yet, so couldn't comment on the Speedo. But have heard the ECU will reset with the battery off, so could be somehting to do with a reset perhaps.

Did it again today, again the wife was at the wheel whilst I was out. Not had time to check volts again but will do first thing in morning. So, it wasn't the loose negative terminal Sad

---------------------------------------------------
2004 Yellow YRV Turbo

Just started doing again this

Just started doing again this week grrr. Rang dealer who said they have only heard of it once and that it might "just want resetting"..........sorry I'm not buying that one.
I then rang Daihatsu UK, AKA I.M. Group (The importers of Daihatsu, Isuzu and Subaru) and spoke to a nice chap who pulled up the details of my car. I then explained what was happening to my car and he thinks it is a voltage issue too. He is ringing me back tomorrow once he has done some digging. Will of course report back when I have spoken to him Smile I could take it to a stealer and get it plugged in but if it could be the battery I'll try it first.

---------------------------------------------------
2004 Yellow YRV Turbo

Spoke to I.M. Group earlier

Spoke to I.M. Group earlier who has confirmed that the most likely culprit IS the battery and that the gearbox ECU isn't getting the required voltage on start up (as already stated on here a few times). I wanted to see if there were any other know issues regarding this problem but according to these guys there isn't. Going to buy a battery and go from there...............

---------------------------------------------------
2004 Yellow YRV Turbo

Suprised they spoke to you.

Suprised they spoke to you. Ive tried several times over the years and unless your a dealership mechanic they dont want to know.
Regards known faults i think its like the governments secrets act....30 years and can go public!

Make sure you get a good battery

Wayne,

Make sure you get yourself a good battery. Varta A14 or A15 get the thumbs up from me as they have the most ah on a battery @ 40ah. Bought a new one from TAYNA batteries (Varta Blue) but had to send it back due to chraging problems. Still waiting them to get back to me on wheather a new battery is heading my way Sad

i got the d4 lol.

well i put my air filter on and bov, the next day stuck in 1st with flashing d4, but it is cold, my scangauge showed ecu was fine, switched off and back on fine all day, today i removed my clock and replaced with a boost gauge(which is 0.6bar), and i had d4 flahing again, think i might get a new battery as it seems to fix it and due to the car being forsale for so long as the price was to high an i think it happened when i was test driving it but sales man never said . tut tut tut,

which is the best battery to get for the yrv, ive always had 063 batterys, cheers guys

054 is the correct battery

054 is the correct battery size type.

But I cant see it being that, As once you start engine you are running off alternator output with 14+ volts.

Probably more related to the cold temp and the gearbox oil thickness when cold.

When very cold i'm now in the habit of sitting at idle for about 1 minute before moving (not too long as thats not too good either for a engine). The gearbox oil is being pumped around torque converter.

I have not seen the flashing D4 yet, But having said that now it will probably happen next time I go out in the car!!

Oh yes this one has been

Oh yes this one has been going on for years. Also to consider is the Gearbox oil change. It is actually stated in the owners manual on one of the back pages that this should be changed every 6 years.

Oh and to come back to the battery question. The biggest battery I have seen that will fit the battery tray is a Varta or Bosch 40aph type battery. But to answer that age old question can you fit a bigger battery?

The answer is yes, but you will have to get a bigger battery tray and depending on the battery put on euro style battery terminal connectors, currently I have done this with mine, and now have a Excide 53aph type 053 Battery fitted with quick release battery terminals:

Mine flashes regularly, in

Mine flashes regularly, in all weathers and in all temps. Cranking voltage seems to be irrelevant. I have even deliberately flattened the battery so it JUSTS starts and it didnt't flash. It has been said, many times, that if the battery voltage drops below 9v (iirc) it upsets the transmission ECU. Member mick49 confirmed this (ex dai. mechanic) and was certain this was the cause. I am lazy and haven't changed my battery YET but it struggled to start this week in the cold so it maybe time - BUT it hasn't flashed this week!! I have changed the ATF, cleaned the sensors, cleaned the connectors - all to no avail. Will change battery and report back after a fortnight!!!!

From my experiences over the years I certainly would not trust the opinion of any Daihatsu UK staff! Be it Sales/Parts/Marketing or Mechanics!

No offence to anyone that relates to! But I have always been less than impressed with the dealers I have dealt with and their knowledge (or lack of)

I'l second that Nathan

I'l second that Nathan. The dealerships ive dealt with seem to have little knowledge and play a guessing game for faults....while racking up the hourly rate bill.
One dealers many years back suggested i take my GTti to their sister branch because they had never seen one and knew nothing. The other branch had a Mechanic who had done his apprenticeship short training course on that model so off i went smiling. Not for long tho, he too said he'd not seen one since and had forgot alot. He suggested i buy the Technical manuals....if they would sell them to me. They wouldnt saying its Dealers only but the other branch after much persuasion eventualy did. Not cheap neither the robbers!
Anyway thats what i do now...buy the manual and repair it yourself...less headache!
I've also chatted and gained knowledge from fellow owners like Nathan (pocketrocket) and Mike Oaks at Camskill etc who have always be more than happy to help.....good guys Smile

I've still not had the flashing D4 issue? Battery is ok and have not yet got round to doing the A/T fluid change.
Daihatsu electronics are usualy Denso which are very reliable but i note the gearbox ECU is made by Fujitsu....ummm and its location in the passenger footwell might not be the best place for moisture and heat etc? I do think makers do inbuilt glitches to help releive us of our hard earned Wink
