Wait, your understanding is that the 1146 is a false positive?
That's <i>not</i> the impression I was given by the service center
crew and others.<br>
<br>
After consulting with the folks in Fremont, the SC is recommending
that I replace the fan motor assembly (USD $998.00). The folks on
TMC generally conclude that the error is related to the under-spec'd
connector under the PEM that drives the motor, and that the
connector pins need to be replaced (both sides). It is
insertion-cycled every year with the Annual Maintenance, but is only
rated for a few dozen cycles, and it's being operated at nearly full
current (no de-rating). A failure certain to happen.<br>
<br>
A few years ago I was getting 1144 alerts (in the cabin!), and
eventually found that the contacts on said connector had in fact
burned, and I had to replace the cable AND PEM. Normally a $10k
repair, but they found a refurbished PEM and swapped them for cost
of the pins and labor. Still an expensive repair at nearly a
grand. So you can see why I'm a little concerned about those events
in particular. <br>
<br>
To be fair, I was also getting some 1116 events in the log a while
ago, and they seemed to have amounted to nothing and mostly have
gone away on their own. I've also gotten a number of 104s and
3001s, which nobody seems to think are important.<br>
<br>
When was the server code updated? The last 1146 alert here was on
10/15. Interestingly, I've had both 104 and 3001 alerts since
then. They appear to be ignorable, and those are not shown in the
car, same as the 1146. How are these alerts categorized? I think
we have some of the logic backwards. In my opinion, the 1144 and
1146 do need to be passed through. I can sleep without the 104 and
3001, but it's good to keep a pulse on their frequency, just in case
there's a sudden up-tick. I'm actually a little more annoyed about
the Possible Theft / Flatbed alerts - they seem to have increased in
frequency since this past spring (before the roll-over), and wonder
if the GPS module is starting to fail.<br>
<br>
If nothing else, we really should ask the Roadster community about
silencing these alerts. I really want to know what's going on with
the car. Matching the limitations of the in-car VMS and decade-old
diagnostic code is not high on my list of project objectives. We
can do a lot better than that.<br>

The server doesn’t have any per-vehicle configuration (other than
authentication), so not sure how this could be easily done server
side.

<div class="">A kludge might be to pickup the notification event

<div class="">But, that said, I’m not really sure why we would
want this. Our goal has always been to mirror what it says on
the little VDS in the car, and that doesn’t show these
debug-only alerts. The solution we have is not perfect, but it
does avoid the worst of them. I have received so many support
questions and concerns from roadster users of OVMS asking
about these over the years - Tesla is aware that they false
positive so labelled them as debug-only, so why would we want
to bombard the user with these alerts every time he
drives/charges the car?</div>

Can we make this configurable? While I understand
that debug messages aren't intended to be seen by the
user, in the 10 years since these cars launched we
have come to know a lot more about some of the, um,
"quirks" in their design. These alerts can be
important! <br class="">

<div class="">Hi folks (Mark, probably),<br
class="">
<br class="">
Interesting... My Tesla Roadster has been
having trouble with its PEM<br class="">
fan, causing a bunch of 1146 Alerts to be
generated while driving and/or<br class="">
charging. I've been monitoring the
situation via OVMSv3. <br class="">
<br class="">
The alerts suddenly stopped a bit over a
week ago. Other events<br class="">
continue to be received (charge start,
stop, key in / door open, etc.),<br
class="">
but not the 1146's. I do a monthly
download of the car logs, and to my<br
class="">
surprise (and disappointment), the 1146s
are still happening.<br class="">
<br class="">
Was there a change to the plumbing
somewhere such that these diagnostic<br
class="">
alerts (perhaps versus user-visible
events) are now being filtered out? <br
class="">
<br class="">
Thanks,<br class="">
<br class="">
Greg<br class="">
