What does EFUSE-W130 mean?
Tesla warning code in the Electronic Fuse (EFUSE) module. This alert will raise when the EPAS1 E-fuse output is faulted as seen by the E-fuse electronic control unit (ECU). This can occur if an unexpectedly high inrush current into the EPAS1 (primary) module or a short circuit event has occurred at the 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 EPAS1 will measure ~0V when it s loaded or ~9.8V when there is an open circuit.?
