OK, some research done. Those are both great resources. I had already found the Russian service manual site, but that anyflip document is also very interesting whilst also remaining somewhat vague on details (which is probably why I understand it!).
From page 80 of that document:
If EV-ECU receives the signal of "DC 330V shut off", it makes turn off the main contactor to shut off the DC 330V circuit and out at the DTC P1B28.
Once SRS ECU send the signal of "DC 330V shut off", it continues to output the signal every time while the power switch is on, unless it is replaced with brand new one.
Once the SRS ECU detects the collision, SRS-ECU and the related parts are required to repair/replacement. Make sure to erase the DTC after the repair/replacement of SRS-ECU and related parts, otherwise the DC 330V circuit never be reverted from shut off mode.
So I need to replace the SRS ECU... or have it reset by one of these online companies. I assume that works as it seems to be big business.
And then I need to be able to clear the fault codes in the car, which I currently can't see, let alone clear!
I have tried to access the canbus with my LELink OBD-II BLE dongle that I hae used for a few years with Leafspy, Torque and CarScanner. Is this a problem with the Imiev? I know it is not on the approved list for Canion. I can connect to it, and the car in Carscanner, but then it doesn't manage to scan through the various ECUs, seemingly getting stuck with those U1111 (active), U1101 (archive) and U1100 (archive). I've also got P1A4C (archive). But I'm not seeing the real picture, not even the P1B28 from the SRS.
A quote from DBMandrake: I have a Scantool OBDLink LX which I bought to use with Canion on my Ion, which it does, however out of curiosity I've tried over a dozen Android based OBD-II scanning apps including the one bundled with the OBDLink and none of them will communicate with the car. All of them report that no ECU's are responding.
That reassures me that maybe the problem isn't in the car but in my dongle/apps.
So, I don't want to try troubleshooting the CAN networks before I know I have a compatible dongle. In order to rule out dongle incompatibility, what should I be looking for instead of my (trusty) LELink? I've been reading up... choices seem to be four fold:
VLinker MC for Canion and other Android apps available for 35€
iCarsoft i909 stand alone available for about 100€
Tactrix openport 2.0 clone with hacked software mut-3 software, price (and probably effectiveness) to variable to quote.
One of my old lexia clones from when I had a Citroen C4. I don't have the software installed anymore and not even sure they would be compatible now... they date from 2010/2011. I used one to set the tarmac on fire while executing a regen cycle on my ***!
I've seen various reports on various options, but not a lot that is specific enough to direct me to a purchase, any ideas?
Oh, and eventually if all (or anything) goes well I'd like to replace the LEV50 cells with the modules from an MG HS hybrid which basically has the same 50Ah capacity just in a rather smaller cell size. They are 90S, but I'll lop off the two spares. This would require getting the bms to relearn capacity or have it programmed... a need to take into account.
Right, I hear a baby crying, have a great Sunday all; and thank you,
Tom.
