Fault codes reference table? w008 f008

Hi guys,

I was wondering if anyone has a table of tesla fault codes that they are willing to share with me, I recently repaired an isolation fault which i could work out with the relevant diagnostics computers I have but one there is virtually no info out there of what these faults relate to.... So i find myself spending countless hours looking though data to try working out what it doesnt like

my current intermittent faults are BMS_w008_HW_HVIL and BMS_f008_HW_HVIL, only seem to be present when car is at standstill in park with doors open, contactors turn off and require you to press the brake to re-enable

I know my current intermittent faults are a BMS fault as it states it as part of the fault but if we had a table with would be very useful for me and Im guessing many others.

Any help is greatly appreciated

Thanks

Gary
 
Hi yes, I reset the original isolation fault and car is running now, I have done approx 500 miles with no faults until today, currently in factory mode

faults that trigger multiple times now are:

DI_W166_HVILOUTOFBOUNDS
DIS_W166_HVILOUTOFBOUNDS
BMS_W008_HW_HVIL
CHG_W034_SWHVIL

1 time
DIS_W086_HVILNOTPRESENT
deltaStatorT missing

You don't say what year your car is, but earlier years had a problem with defective switches and connectors.

In any case you've read the Tech Note. It's likely a bad connection somewhere in the HVIL loop. DI_W166_HVILOUTOFBOUNDS and DIS_W166_HVILOUTOFBOUNDS are general and expected. BMS_W008_HW_HVIL too.

First place I'd check is CHG_W034_SWHVIL, the charger lid switch. Hell I'd go ahead and replace it if you can get the part. Pull the low-voltage connector on the charger, check all pins, and re-seat it.

Do not do this if you are not highly trained in working with high voltage. 400vDC will kill you dead.

I did this, it actually fixed itself but went ahead and checked connections, I couldn’t see anything wrong but cleaned and greased all connections with contact cleaner and non conductive grease. Ran fine for a while, now I have CHG_w101_lostCommsPhase as a permanent fault, it tripped the rcd when charging at work, got to a SUC and failed to charge, charges on AC now but no DC,
