I-stop malfunction
« on: January 15, 2019, 12:43:46 PM »
Hi all.
Mazda3 Sport satnav 2010:
The I-stop amber indicator warning light has just decided to remain flashing on my vehicle.
As I never use the car in I-stop mode I was wondering if there would be any major negative consequence long-term in ignoring the issue rather than setting myself up for a vast bill from Mazda in dealing with it?

It could be something as straightforward as swapping out the 2nd battery for a new one to make the I-stop work correctly again. I don't think you'd have any other problems if you don't use the I-stop, I never used it in all the time I had the Gen 2 Sport (6 years) although it was still operating on my car when I sold it. Main ignition works off the big battery so it shouldn't cause problems with that in any case.

Hi.
Ok - will take a chance on ignoring it for the time being as I have read in several places (right or wrongly) that it is also possible to over-ride it altogether by disconnecting a microswitch by the bonnet release.

Given the time of year have you been using the air conditioning/heating more than usual maybe? Possible the battery could be on the way out and/or you've been drawing on it a lot. Mine is the next generation and I let it do it's thing but I've noticed it gets stuck like you describe as it's giving the battery a chance to catch up again sometimes. On mine there's a monitoring app on the Mazda Connect screen that confirms it's the battery that's not "ready".
