Good thought - it would also be good to know the rough temperature when the fault occurred in case it is related also. I don't think anyone has reported it happen whilst driving, it always seems to be found when they get in in the morning.

Yup, I use OPD extensively. And the fault first occurred in the morning, but not a cold one TBH.... like 10 degrees C.

Don't know about fault codes or detailed diagnostics, but my dealer explained that the part in question has two separate sensors to measure brake pressure. When the sensors have unequal measurements, problems arise.EEEE wrote: ↑Wed Mar 06, 2024 1:54 pm And they wonder why people are reluctant to switch to EVs. Whilst people might see that as hyperbole unrelated to the car being an EV - the part in question wouldn't be nearly so complicated/expensive/fault prone if it was an ICE equivalent.
I would hazard a guess that the failure of the module is not even absolute. It would be interesting to know exactly what fault code is reported by the module to see if it can be repaired somehow. ABS units often have simple failings and can be rebuilt for a fraction of what was mentioned above. If anyone can get detailed fault diagnostics that would help people in the future (just think, 10 years from now someone will want the info and the original owners will have long abandoned their accounts on this forum).
I don't use OPS at all, as I use ACC quite often. I was eased into the issue a few weeks before Christmas 2023, as it would disappear after restarting the car. This happened a few times in the morning (my garage) or after standing outside half a day during work. Finally one week before Christmas the problem didn't go away anymore. I think at the time temperatures were cold but not freezing. More or less typical (Belgian) winter weather.MattHero wrote: ↑Thu Mar 07, 2024 3:16 pmYup, I use OPD extensively.

That's great information Peter-E!
It means a couple of things to me. ABS regulators fail with pressure sensor faults, common enough to be found via google searches, and they can be rebuilt by third party rebuilders.
It also means that the fault is not logged as a permanent failure. That is to say if the sensor is intermittent, as long as it passes the continuity/pressure check initially , then the unit is probably good to go. EG it's not like an airbag ECU or sensor which permanently goes into deployed mode after an accident.
Given the massive cost of replacement, I'd say its worth a punt taking it to an independent, have the unit removed from the car and sat idle for a week, and send the booster/modulator off to a refurbishment outfit and see what they make of it.
I was quite surprised to see how common ABS modulator problems (pump/block/electronics) are on modern cars and was happy to find several refurbishment companies that undertake repair.
Assuming the error is not in the booster part or some other mechanical failure, I suspect the pressure sensors are common parts (or common enough to ABS modulator refurbishment companies). Even so, the ABS refurbisher will most likely be an excellent electrical repair specialist also.

Just back from my appointment with my dealer on my own failure and they've diagnosed as expected the (now dreaded) simulator failure (part: Electric Servo Brake (“Brake Booster”) - 01469-TYF-J01 SIMULATOR SET, BRAKE OPERATING (REWRITABLE) as discussed in the spares part thread). I've been given the same ~£2600 odd estimate for repair as others and a time estimate of a few weeks minimum, to be updated once the part has been ordered.
A few points of interest from the dealer;
- Honda have offered a contribution of £500 in some cases towards the cost of the repair on some vehicles. This is dealer requested, and I'm sure we'll all have opinions on how generous or otherwise such an offer might be, should it be made.
- While this is the first e they've seen with the issue, it's know to them as the part is shared with the current Jazz (unclear on specific MY and models here) and they already have a number of those awaiting repair in their yard. Given how many Jazz Honda sells, this is significant number of failures in the offing you'd presume? The characteristics of the failure are identical across both models.
- Honda Japan have a recall on the models affected by this part, but it is not in place in Europe yet. Again, I don't know whether they mean just the Jazz, the e or all vehicles that use that same part.
Not had a chance yet to do any further research to confirm either of these pieces of information, so don't treat them as fact just yet.

A quick google and here's a suggestion on some of the other models with failures;

And the apparent recall in Japan;
https://www.honda.co.jp/recall/auto/inf ... Nc6C38cmZ4
"July 27, 2020 ~ January 24, 2020"
Seems to indicate only the first 6 months or so of manufacture here? I'm certainly in that cohort, but is everyone affected also an early car?
EDIT: Just noticed that the date on that recall is "Notification date: December 8, 2020", which given that the estimate at that point was that there over 500k vehicles carrying the faulty part, is incredibly frustrating that we've had to find out by accident through individual failures.

My Google translate says:
Notification date: December 8, 2020 and that the dates for the e are July 27, 2019～January 24, 2014 which don't make sense.
Have checked with the wife (Japanese) and she says the notification date is 08/12/2023 and that the date range for the e is 27/07/2020 - 24/01/2022.
Still quite a while for the recall not to have made it to Europe - doesn't exactly fill you with hope that it ever will.
@MattHero - does your car fall within those dates?
