</div>
<div>I've been following along mostly and have been periodically
going over the poller code trying to work out if there are any
points where there could be timing issues with long-held
mutexes (or even deadlocks). I did push up some small tweaks
recently but there was no aha! moment.</div>

</div>
<div>I have been working on some changes that would move forward
on the idea of building a vehicle implementation from duktape
scripts... and I had been getting some points where ovms went
berserk, kicked out the ssh session and stopped responding on
ssh http but then eventually came back (without a reset) after
some minutes. The script was simply adding a new
PollSeriesEntry which then uses the dbc decoder (with
improvements) to decode to metrics, noting that the script is
setup only and that there are no call-backs into the duktape
engine/task.</div>
<div> </div>
<div>Anyway, those patches mentioned above seem to have resolved
that issue with the hangups which is why I made the p/r.</div>
<div> </div>
<div>BTW I have been running my Ioniq5 with the latest of the
timing patches for a while now.</div>
<div><br>
</div>
<div>Because of the correlation of the bus issues with the
poller changes, I am still concerned that the poller changes
are contributing to the problem (even if not directly causing
it), so would be happy to chase down any leads people might
have. </div>

<div>Check your DTCs with leafspy,
if it shows a bunch of DTCs
including a B2604 BCM Shift PN

<div>I did indeed have B2604-00, along
with nineteen others. Most of these
mention CAN errors, and it seems
plausible that low 12v could be a common
cause.</div>
<div> </div>
<div>Do you think this rules out a poor
OVMS OBDII connection? I'm thinking if I
have high resistance in that connector,
then OVMS will experience low voltage
but the rest of the car modules will
have good voltage.</div>
<div> </div>
<div>However I see codes that suggest
communication errors between Nissan
modules:</div>
<div>C118C-01 ABS Brake: Malfunction is
detected in VCM system. Control module
communication issue.</div>
<div>B2064-00 BCM Shift PN Diag CAN:
Park-Neutral position switch signal
discrepancy</div>
<div>C1A70-01 BRAKE: Malfunction is
detected in ABS actuator control unit
system</div>
<div>U1266-02 MULTI AV: Malfunction is
detected between the AV control unit and
TCU</div>
<div>U0428-00 AVM: Invalid data received
from steering angle sensor module</div>
<div> </div>
<div>So I'm thinking perhaps the whole car
briefly had low voltage.</div>
<div> </div>
<div>To try to fix this, I cleaned the 12v
battery terminals and performed a long
charge. After clearing the codes, I have
only two codes that reappear.</div>
<div> </div>
<div>P317E-00 EV/HEV HV Battery System
EVC-249 (perhaps caused by <a href="https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/issues/1061" rel="noopener noreferrer" target="_blank">#1061</a>)</div>
<div>U1A06-15 TCU Communication incorrect
calibration (probably because I've
removed its antenna)</div>
