EFUSE_w135_condenserFanEFuseTrip
What does EFUSE_w135 mean?
Tesla warning code in the Electronic Fuse (EFUSE) module. This alert will trip on whenever the HVAC rail is turned off. This is expected and should be ignored, shall be fixed in future versions of firmware. This alert will raise when the condenser fan channel is faulted as seen by the E-fuse electronic control unit (ECU). This can occur if an unexpectedly high inrush current into the condenser fan or a short circuit event has occurred at the condenser fan output of the E-fuse. Another possibility is that a long current event, which exceeds the current carrying capability of the cable, has occurred. Once the E-fuse is tripped (turned off), the output will measure ~0V.
