ICC not working

Nicholas53 · 15-01-2020, 08:38 PM

Hi I'm new to this forum I have a BF xr6 mk2. The radio doesn't come on the, controls for the vents, and the aircon controls aren't working either the hole unit is dead. Can anyone tell me what could be the possible cause.

If you slightly turn the key switch, do they come on?

Check fuses with a test light
Was it working previously
Have you had ICC out
Check accessory relay in interior fuse box
Does radio work but no display if so push and hold main power button for 5-10 seconds
Try disconnecting main plug into front of interior fuse box and reconnecting
Try removing icc reset plug at rear by pulling it towards you slightly and refitting
Does everything else work ie. wipers flashers etc.
Do reverse lights work

Nicholas53 · 16-01-2020, 08:23 PM

The wipers and flashers do work. The reverse lights don't work but they havent worked since I had the car. There is a problem with the TCM but the radio was working then. Will check the accessory relay. Fuses are all ok.

Double check reverse fuse with a test light

Could be the motherboard in the back of the ICC (The central dash unit with the radio, A/C buttons, screen, etc). The solder joints on the board start to seperate/dislodge/corrode /whatever the technical term is

... and things stop working.

I've replaced a few ICC's over the years (in different cars) when this has started happening... but late last year we decided to have a go at fixing one instead.

I took the ICC out, and pulled the motherboard out of the big rectangular metal box at the back of it (not the CD player... but the one with the big main plug on it)... then I gave it to my mate James who's good with electronic boards... and he touch soldered all the solder joints on the board... then I re-installed it and put the ICC bac together.

That was around Sept last year and everything is still working reliably

Before you try this yourself, just note that the car won't start once the ICC has been removed ( I've got other cars, so didn't matter for me). I've also got a couple of spare ICC's (kept some previous stuffed ones) so I had back up.

If you choose to fit another ICC, you'll probably need to get it security coded to the car (though, sometimes you can be lucky it just works). Car will start but the rest won't work until it's coded.

Good luck sorting your issue

Thanks for pointing me the right direction will try that I have a spare unit at home. also have another vehicle so I can give it a go will let you know how it turns out.

Replace icc and push am and menu buttons at same time will allow you to test for about 5 minutes until programming is done with a scan tool remember to reset plug at rear by pulling towards you slightly
change the bem at bottom of original icc into new icc if you want it to start

Nicholas53 · 25-01-2020, 03:30 PM

I replaced the main board as you suggested and it all works fine now. Thanks for the tip really pleased with the result.

Hi everyone, I have been installing/programming ICCs in falcons BA BF and FG series and Territory SX SY series.

Recently encountered a weird problem.

A guy came for dead ICC replacement for his BA XT falcon.

I installed another unit which didn't work either. I decided to install a tested working unit from my own territory to make sure that the unit being installed is fully working.

Event that unit didn't work.

At this point the owner of the car disclosed that he had bought another working ICC and tried to install but didn't work. So, he installed it back in the original car from which it came but unit was dead or in simple words unit was killed by his BA Falcon.

I was sure that his car has burnt 2 of my ICCs also.

To verify that I installed my previously working unit back into my territory and it was dead as expected. No display, now switches working.

I was left with 2 of my units rendered useless by his BA along with 2 hours of time.

Story didn't end here. Now I've tried another tested working unit in my territory but still the no display and none of the switches working.

I suspect that the BA Falcon may have a faulty BCM which is causing some voltage surge killing the ICCs.

But have no clue about my own Territory as even another tested working ICC is not working in it.

Before I start to replace and program the BCM in my territory I would appreciate the inputs from experts.

I have a few spare BCMs and ICCs, professional scan tool and tools for repairing motherboard if needed.

Thanks in advance.

Check reverse lights work
Check pins on rear of icc haven’t bent over

Thanks mate. No bent pins and reverse lights working.

Car starts fine, centre locking works, interior lights do come on and off. But none of the switches on ICC itself is working.

Have you checked all of your fuses ?

Hey mate did you ever solve the problem? I’m currently in the same position and can’t get a rwc without my icc working, may I know what you did to solve your problem.

Oh ok thank you

foxtrot3 · 04-12-2020, 07:40 PM

Hi. Pull the ICC out and see if any of the terminals in the plug on the dash have been pushed out of the back of the plug by a bent pin on the first faulty ICC. Main pins to check are the B+ on the bottom edge far right and the acc and ign feeds on the top row near the centre of the centre section of the plug and the ground wire above the B+ power wire on the right hand edge. The main thing I would be looking at is the B+ feed as radio should work in key-less mode without acc or ign and it should earth through the side brackets upper bolts and the antenna module if the earth pin is gone. If all the terminals are in place the next thing is to see if there is power on the B+ terminal. Good luck. MD

Did u get it fixed? I was told by auto elect that console has to be replaced. An earlier thread said someone resoldered the points on the motherboard. I had a solar inverter which electrician said needed throwing out(including panels). Found someone who resolders the boards. Saved thousands. still working after 3 years

Dez096 · 27-07-2022, 06:34 PM

Hey guys I’m pretty new to the ford forums just got accepted in thank god I did!! I’m having some trouble with a bf xr8 icc pretty much it was working a few days ago and it was working fine kinda cut in and out but as soon as I smacked the side it would start working again, after a while it completely stopped on me I pulled out the icc and checked all connections were correct and everything looked fine replaced all fuses and relays and that still did nothing at all. Would like to know if there is a certain sequence to put the plugs back in also I’ve put in rear speakers because the car never did come with any and I didn’t earth them would that be causing a short? Also did take out the icc with the battery connected if that would mess with it to? Thanks!!

Hi.

sounds like the pins at the back have 'broken' away from the motherboard & need to be resoldered [the ones that plug into the white socket in the dash]. re speakers - don't earth them. re battery .... i always disconnect the battery so there is no issues when actually disconnecting/removing the ICC/BEM, nor any problems when reconnecting the ICC/BEM.

Cheers

Dez096 · 27-07-2022, 09:11 PM

Just to make sure I’m thinking of the right pins but as soon as the icc comes out your talking about the connector plug to the actual icc unit? If so I checked them pins they are absolutely fine but if you mean the actual motherboard on the icc?? I’ve tested it all like the plugs on the bottom of the icc they all give power and it all lights up just nothing on it works, sorry just making sure before I go pulling out a motherboard and soldering. Thanks

Tomb · 27-07-2022, 10:00 PM

I went to auto electrician. They had the exact same model there.alternative was to send it away to be resolderef for around 300 to watch 400

you mentioned thumping the side of it .. hence why i mentioned the motherboad/pins.

No absolutely nothing happens

Its a feature. I do use it if for example doing a long trip at night on un lit roads. So to turn this feature on/off you hold the power button for a few seconds. Every time you make an input the screen will turn on for 5 or so seconds then back off again. So your icc is not faulty, its just a feature.

yep & it's good to know. hers does it as well as mine - does it on all colour screens but no idea re mono DZ screen [dual zone] or mono screen SZ [single zone].
