Description

INFOID:0000000004211801

The hybrid vehicle control ECU detects this DTC and effects fail-safe control if the engine or hybrid transaxle

gear has seized up, or foreign objects have been caught in either of them.

NOTE:

If this DTC is output, the engine or hybrid transaxle gear may be seized up. Be sure to check the level of the

engine oil, hybrid transaxle oil (ATF), and coolant before inspection.

1.

PRECONDITIONING

• Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with

converter assembly, take safety precautions such as wearing insulated gloves and removing the service

plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent

other technicians from accidentally reconnecting it while you are working on the high-voltage system.

• After disconnecting the service plug grip, wait for at least 10 minutes before touching any of the high-voltage

connectors or terminals.
