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.

so was it a dead end re BEM?
