What the PLCRLY system covers

PLCRLY 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.

PLCRLY_a057 PLCRLY_a057_evseFaulted	Caution	Alert	PLCRLY_a057 - evse Faulted Tesla alert code in the PLCRLY (PLCRLY) module. PLCRLY (Power-Line Communication (PLC) relay)
PLCRLY_a062 PLCRLY_a062_scOutOfService	Caution	Alert	PLCRLY_a062 - sc Out Of Service Tesla alert code in the PLCRLY (PLCRLY) module. PLCRLY (Power-Line Communication (PLC) relay)
PLCRLY_a063 PLCRLY_a063_scUpdateInProgress	Caution	Alert	PLCRLY_a063 - sc Update In Progress Tesla alert code in the PLCRLY (PLCRLY) module. PLCRLY (Power-Line Communication (PLC) relay)
PLCRLY_a064 PLCRLY_a064_superchargingBlocked	Caution	Alert	PLCRLY_a064 - supercharging Blocked Tesla alert code in the PLCRLY (PLCRLY) module. PLCRLY (Power-Line Communication (PLC) relay)
PLCRLY_a065 PLCRLY_a065_selfTestFailed	Caution	Alert	PLCRLY_a065 - self Test Failed Tesla alert code in the PLCRLY (PLCRLY) module. PLCRLY (Power-Line Communication (PLC) relay)
PLCRLY_a066 PLCRLY_a066_proxLatchedIdlePilot	Caution	Alert	PLCRLY_a066 - prox Latched Idle Pilot Tesla alert code in the PLCRLY (PLCRLY) module. PLCRLY (Power-Line Communication (PLC) relay)
PLCRLY_a077 PLCRLY_a077_invalidMacAddress	Caution	Alert	PLCRLY_a077 - invalid Mac Address Tesla alert code in the PLCRLY (PLCRLY) module. This alert signifies that the MAC address for the power line communication (PLC) relay is not programmed or is programmed with a value that is out of range. This is not a Tesla owned MAC address. In this case, the PLC Relay will fall back to a default MAC address, meaning the charging functionality should not be impacted by this alert.
