I work with Windows professionally Russ and apart from my Lexia I have no Windows machines at home at all. I'm all Linux... Make of that what you will Let's just say I'm not a fan.... I couldn't go back either. I love my Linux
A good and successful day today. feeling a bit perkier so I've been gently playing XM electricals. I've fixed my aircon I now have a blower that works properly last time I looked I saw an unvarying +5V at the blower regulator control line and assumed the climate ECU was dead. Swaps of two good ones later I realised it wasn't.. Today I paid a bit more attention to the blower regulator and noted it was an after-market job and it looked brand new. I had a spare Xantia one in stock but that didn't work either but caused the fan not to run at all! After a set of new transistors were fitted to the Xantia one all was happy and the blower works, temperatures regulate and the aircon blows cold. Excellent!
I was curious to see wht the new after-market one wouldn't work. All seemed OK and then I noted the markings on the transistors was a bit indistinct but it looked like they were MJ11016 rather than the correct MJ11015. odd.
I looked up the data on the MJ11016 and found they are the complementary NPN to the PNP MJ11015 so no wonder they wouldn't work. Gawd knows where this module came from but it was never going to work with the wrong trannies in it, that's for sure and it was how it was made as the transistors are riveted in...
EDIT: I prove they were the wrong (NPN) sort by testing them so they're definitely MJ11016!!!
I then turned my attention to the non-operational cruise control. All tests tell me the ECU is dead as the vacuum pump and dump valves work a treat, all signals and voltages are correct, including the speed signal which I tested by rigging up a battery-powered oscilloscope on the passenger seat, some very temporary wiring and going for a very short drive.
Easy I thought. I have a spare S2 Xantia cruise ECU in stock but they're just different enough not to want to play
So, I need a new ECU. Anyone got one please? The Hella part number is 5GA 004 397-17. I know a Xantia S1 one is the same as well but not the Xantia S2. How bizarre...
A good day but a bit knackered now. Next I'll see why I can't speak diagnostics to the gearbox ECU...
