What does CHG_w116 mean?

Tesla warning code in the Charger (CHG) module. The master charger detects an over-temperature condition within the high voltage junction box (HVJB). The temperature sensor is internal to the HVJB and is communicated to the master charger. The temperature reading of the HVJB sensor should be 66�C by default because that is the floor of the sensor value, and it will start logging temperatures above 66�C. This warning is set when temperature is above 70�C.
