Hi all,

Long time lurker but have had some great help from some of the guys here over the years.

I currently have an 01 M35 Stagea. Great car and I've kept it standard, so far, other than removing the front prop shaft as the forward universal was shot and nobody seems to be able to supply or repair.

But, went to drive off today after being parked overnight and ...

No climate control, which was stuck on the last setting with the fan on full bore. No radio, no climate control display. No pop-up screen display. Also, the wing mirrors don't swing out as they usually do.

Nobody I've spoken too today has heard of this, so thought I'd ask here.

I've checked all three fuse boxes and all fuses test good.

Any ideas ???

Cheers

Scott

check all the fuses, I had go in my R32 GTR that stopped the windows and instrument cluster and the fuse was marked something else all together

Thanks for that.

Pulled and checked all fuses one by one, with multimeter. All good.

Cheers

yup, its a known issue.

I don't know the details but there are many accounts of something that goes dry solder os something that gives up in the central fascia unit. It takes out the radio and AC at the same time.

Have a search, I think the V Series section has some more info on it, but basically your looking at an expensive fix, or by a secondhand unit and fit it in. Do some searching on the site, I'm sure you'll find more info.

Thanks for the Info PN-Mad

I searched previously, but couldn't find anything other than mention of the ignition key position and wear factors in the ignition barrel.

No mention of the wing mirrors being involved either.

Another possibility is apparently the BCM failing? Although its strange, as the car starts and drives with everything else working normally ?

Yeah, thats what I thought at first too, except there's no mention of the wing mirrors failing. And they're nowhere near any stereo wiring etc.

Plus, the stereo head unit was replaced 5 months ago, with one from a 50,000 km car.

Checked for water/moisture behind the battery, and in the drivers kick panel fuse box?

Thats cause a few weird ones of late.

Yep, and I had the same thing happen just a few months back.

Major corrosion in the module behind the battery, that'd obviously been going on for years. Removed and replaced all corroded parts and has been working fine for almost 5000kms now. But it was the first thing I checked and all appears ok there. I guess it's possible that its developed another fault related to the first, but the issues with the radio, climate control and mirrors all point towards something else, IMHO anyway.

Tested battery? May be working but weak? Checked earth(s)?

Battery tests ok, and it should have full voltage when running anyway.

Tested most of the visible earths, but will hunt for the hidden ones today and check.

whenever i get anything electrical i always start with removing, scrubbing and re attaching all groundwires, they do the most random things when they dont get the contact they wish.

chepaest and easiest things first.

Firstly do the mirrors fold and unfold using the folding switch? Have you checked that the button to enable the automatic folding feature hasn't been accidentally bumped?

Does it have a japanese dealer fitted alarm? Is the alarm working? Usually the folding mirror box is located under the steering column mine was plugged into the alarm box, first thing I would do is check the scotch locks, on everything fitted by the japanese. Motion disable, folding mirror feature.

You haven't mentioned if the head unit is actually getting power? Is it turning on?

Since this is all happening at once sounds like a ground issue/loose connection?

In the series 2 with the climate control going full ball and AC on lowest is usually caused by a flat cable that connects the front panel to the bose unit which is passed through to the cars loom. So if the bose unit isn't getting power correctly, I suppose an issue like this would occur.

Who replaced the head unit?

Mirrors don't fold or unfold using the switch. But the mirrors fold in with the alarm remote, as usual, if you manually pull them to the out position first.

Alarm remote is in the key ? Checking scotch locks now - didn't think anyone used them since the '80's ? They were great for fitting Cobra & Piranha alarms when I used to work for them though ;)

Head unit is not turning on at all, but haven't pulled it out to check power yet.

I replaced the head unit. No problems that I remember.

Sounds like the common Bose stereo issue to me...

Ditch it for an aftermarket head unit and dual din facia, why would you waste your time sticking an OEM back in.

Yep, I agree. But an aftermarket unit won't work either without power going to it !

No power coming through the loom to the head unit. No constant, ignition or standby.

Also, powered the battery in the car with another via jumper leads, just to check that the current drop on start wasn't too great. Nothing changed.

Had the head unit out and checked earths, connectors, loom etc. All looks normal. Checked BCM wiring and loom - nothing obviously wrong. Alarm is connected next to BCM via 4 x scotch locks. All connections test ok.

Cleaned and re-fitted all visible earthing points under bonnet.

Cheers

Scott

      Thanks heaps Duncan and GTSBoy. I'll get my old man to sit in the driver's seat and turn it on and off while I test with the meter. Or maybe other way round, depending on whether he remembers where his glasses got to

      This is the GTR fuel pump. Yellow shows 12V, orange shows earth. The ECU provides the earth to activate the fuel pump relay. The ECU side of teh relay will pull low when the ECU activates. This is the RB20 fuel pump. Almost the same, but a little simpler. You can see I indicated (above) where the 12V line goes down to the RB20 diagram on the overall diagram, whch shows both RB26 and RB20. This is where I show it coming in on the RB20 diagram below. You can see that the dropping resistor is handled differently. When the fuel pump control is not providing earth to the pump, the pump earths through the dropping resistor and thus runs at lower voltage (some is wasted over the resistor) and runs slower. I showed that "not 12V and not quite earth" portion of the wiring in a paler orange. The rest of the wiring that I did not colour on that little section below the pump would be orange when the fuel pump coontroller is providing earth. This drop is handled inside the fuel pump controller in the GTR. Regardless, you can see where 12V is supposed to be, where earth is supposed to be. The key on prime is via the ECU providing the pump for only a few seconds the switching off. You should be able to see that happen.
