What PCS_a041 means
PCS_a041 means voltage from the charging equipment is outside acceptable range. Most commonly a problem with the charging station or electrical supply rather than your Tesla.
What to do
✓ Try a different charger first. This is usually not a vehicle problem.
1
Try different charging location — Move to different outlet Level 2 station or Supercharger.
2
Avoid extension cords — Never use extension cords for EV charging — they cause voltage drop.
3
Check home electrical circuit — Have electrician verify circuit voltage is within spec (240V plus or minus 10%).
4
Contact charger provider — Report consistently faulty public chargers to the network operator.
