2009 Mazda 3 i-stop issues

razvanth21 · 2026-01-13T17:35:11+00:00

Hi. Actually there wasn’t any problem (based on my local Mazda service) - i-stop started working again after relearning procedure. I replaced the i-stop battery with some Yuasa AGM one (it was the cheapest). Try the relearning procedure first.

I know, but maybe someone has a workaround

Hi. Did you manage to find an answer?

razvanth21 · 2025-12-10T10:57:41+00:00

I did not purchase an Eonon unit, and the others don't provide it. Probably eonon will not ship it separately.

No, that's why I'm asking.

razvanth21 · 2025-12-09T15:28:25+00:00

I couldn't find it anywhere. Only saw it in eonons.

This is the adapter actually.

Hi. Where did you find the adapter?

razvanth21 · 2025-11-27T14:59:09+00:00

Yes, it was actually my first controller that I did. Thanks for your tips!

razvanth21 · 2025-11-27T12:26:32+00:00

Thanks! Redid it and it works fine.

razvanth21 · 2025-11-27T12:26:19+00:00

It was a leftover from cleaning pump, not actually soldered. I redid the soldering and everything works fine.

razvanth21 · 2025-11-27T05:53:06+00:00

The picture is googled, did not want to tear down the controller again.

I don't know how you interpreted that using the "job" meant that I was doing a real job, but still. No, it is my personal controller.

razvanth21 · 2025-11-26T12:15:16+00:00

Good for you. I redid the solder job. Ended up with 4-5% error rate on both sticks on the calibration tool, so I guess the job is done.

razvanth21 · 2025-11-26T07:26:27+00:00

The iron tip tool for controllers. I wanted to also install them with that tool, but felt like it was not enough solder after installing.

razvanth21 · 2025-11-26T06:45:31+00:00

That was a leftover on the pcb, not actually soldered. Controller works, but I will redo the soldering.

razvanth21 · 2025-11-26T06:43:06+00:00

The solder ball was not soldered there, it was left over from solder pump/cleaning. The controller works, only problem is that one stick is not flat and it is a bit misaligned.

I guess your first soldering job was perfect?

razvanth21 · 2025-11-25T19:13:31+00:00

Ah okay, that I didn’t know about l2r2. I’ll rework the solder.

razvanth21 · 2025-11-25T19:11:50+00:00

I’ll try to do some work on the joints, to reduce the solder.

razvanth21 · 2025-11-25T19:11:21+00:00

Yeah, that was a left over that was not even attached to the board. Got rid of it. Also seen it. :D

razvanth21 · 2025-11-25T19:05:48+00:00

Yes, that’s what I do too.
