| CHG_w070 CHG_w070_inputVoltMismatch | Warning | Warning | CHG_w070 - input Volt Mismatch Tesla warning code in the Charger (CHG) module. This alert indicates the voltage sensor in the Gen 3 charger's VI board does not match the voltage sensed by the charger's phase board. |
| CHG_w083 CHG_w083_allPhasesFaulted | Warning | Warning | CHG_w083 - all Phases Faulted Tesla warning code in the Charger (CHG) module. The alert is set if all phases have used up their retries and are in a faulted state. The cause is most likely exterior to the charger. |
| CHG_w111 CHG_w111_AttemptToFastCharge | Warning | Warning | CHG_w111 - Attempt To Fast Charge Tesla warning code in the Charger (CHG) module. The vehicle is unable to supercharge or fast charge. |
| CHG_w116 CHG_w116_HVJBOT | Warning | Warning | CHG_w116 - HVJBOT 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. |
| CHG_w117 CHG_w117_HVJBOTFault | Warning | Warning | CHG_w117 - HVJBOT Fault Tesla warning code in the Charger (CHG) module. The charger has detected an overtemperature event in the high voltage junction box (HVJB). |
| CHG_w118 CHG_w118_VDiffHwRationality | Warning | Warning | CHG_w118 - V Diff HW Rationality Tesla warning code in the Charger (CHG) module. The Voltage Differential rationality check fails possibly due to a failed isolator between phases or a failed signal line for the voltage differential. This alert can affect the ability to supercharge when aligned with the alert BMS_A096_FC_NO_VOLT_MATCH. This alert does not seem to affect AC charging. It can be present when the contactors are closed or opened. |
| CHG_w120 CHG_w120_HVJB_powerFault | Warning | Warning | CHG_w120 - HVJB power Fault Tesla warning code in the Charger (CHG) module. The high voltage junction box (HVJB) 12V power supply is below 11.54V. |
| CHG_w124 CHG_w124_ph3VersionMismatch | Warning | Warning | CHG_w124 - ph3Version Mismatch Tesla warning code in the Charger (CHG) module. There is a version mismatch. |
| CHG_w125 CHG_w125_leakageTestFailure | Warning | Warning | CHG_w125 - leakage Test Failure Tesla warning code in the Charger (CHG) module. This fault indicates that the voltage decay after the supercharger external isolation test has happened too quickly. During supercharger startup, the supercharger will open the output contactors after performing the external isolation test at 300V. The vehicle then monitors the time it takes for the 300V to decay. If the decay time is sufficient, the start-up sequence proceeds. The purpose of this test is to check the common mode isolation (DC+ to DC-) of the high voltage chain from the supercharger cabinet to the vehicle's fast charge contactors. |
