What does EFUSE-W155 mean?
Tesla warning code in the Electronic Fuse (EFUSE) module. The temperature sensor for the 12V battery is disconnected from the E-fuse and reporting open circuit on the harness. This will result in a default voltage set-point being used for charging the 12V battery, which will not be optimized for the present temperature. As a result, it is likely the 12V battery life will be reduced.
