TVR Tuscan immobiliser problem resolved
Discussion
Had a brand-new conundrum thrown at me today by my equally beloved and detested Tuscan. Resolved it in the end and felt I should post the resolution here if it can prevent some other poor bugger from taking a sledgehammer to the delicate bodywork.
So, out of the blue, the immobiliser refused to disarm, i.e. pressing the key fob did not light the oil lamp. Nor did it help to insert the plug into the dashboard socket. (Strangely enough, as the ancient ritual of inserting thingies into other thingies has been seen as highly beneficial and pleasurable throughout millennia.)
I thus proceeded with that other ritual only known to the TVR tribe and proven to work, and disconnected/reconnected the main fuse in the passenger footwell, following the 30s waiting time as proscribed in miscellaneous holy electronic scriptures. Alas, to no avail, as it only resulted in the window LEDs flashing feebly. NOT as has until now been the case – the flashing of turn indicators and alarming of car, and the car reaching Nirvana.
‘Tis time to check the immobiliser connections, I thought; but then I might as well check the fuses first, as they’re in an equally impossible-to-reach location. Or, rather, I had my wife, the contortionist, do it. (I did ask prettily.) Both fuses were OK, but as she put in new ones, just to be safe – everything reset itself. And now everything functions!
Conclusion: Don’t assume the all-mighty main fuse workaround will always be successful! Get to the bottom (literally) of the problem, particularly when dealing with the immobiliser.
