What the CHGS system covers

CHGS alerts belong to Tesla's proprietary diagnostic alert system and are grouped under the network category.

Read all active alerts together instead of diagnosing a single code in isolation.

Check recent service, firmware updates, and low-voltage battery condition.

Use Tesla Service or a qualified EV technician for safety-critical systems.

Code	Severity	Type	Description
CHGS_d001 CHGS_d001_replaceCharger	Info	Diagnostic	CHGS_d001 - replace Charger Tesla diagnostic code in the CHGS (CHGS) module. The alert indicates a potential internal hardware issue with the charger.
CHGS_d011 CHGS_d011_proxRationality	Info	Diagnostic	CHGS_d011 - prox Rationality Tesla diagnostic code in the CHGS (CHGS) module related to prox rationality.
CHGS_f083 CHGS_f083_allPhasesFaulted	Critical	Fault	CHGS_f083 - all Phases Faulted Tesla fault code in the CHGS (CHGS) 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.
CHGS_f114 CHGS_f114_phEnRationality	Critical	Fault	CHGS_f114 - ph En Rationality Tesla fault code in the CHGS (CHGS) module. This alert indicates that the phase enabled state for a particular phase is different than what is expected.
CHGS_f116 CHGS_f116_HVJBOT	Critical	Fault	CHGS_f116 - HVJBOT Tesla fault code in the CHGS (CHGS) module. The Slave Charger (CHGS) is detecting an over-temperature condition in the High Voltage Junction Box (HVJB).
CHGS_f118 CHGS_f118_VDiffHwRationality	Critical	Fault	CHGS_f118 - V Diff HW Rationality Tesla fault code in the CHGS (CHGS) module. The Voltage Differential Rationality Check fails, which is possibly due to a failed isolator between the phases or a failed signal line for the voltage differential.This alert can be present when the contactors are closed or opened.
CHGS_w083 CHGS_w083_allPhasesFaulted	Warning	Warning	CHGS_w083 - all Phases Faulted Tesla warning code in the CHGS (CHGS) 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.
CHGS_w124 CHGS_w124_ph3VersionMismatch	Warning	Warning	CHGS_w124 - ph3Version Mismatch Tesla warning code in the CHGS (CHGS) module. There is a version mismatch.
