CAUTION:
-
Confirm that DTC P0AA649 (Hybrid / EV Battery Voltage System Isolation Internal Electronic Failure), P1C7C49 (Hybrid / EV Battery Voltage System Isolation (A/C Area) Internal Electronic Failure), P1C7D49 (Hybrid / EV Battery Voltage System Isolation (Hybrid/EV Battery Area) Internal Electronic Failure), P1C7E49 (Hybrid / EV Battery Voltage System Isolation (Transaxle Area) Internal Electronic Failure) or P1C7F49 (Hybrid / EV Battery Voltage System Isolation (Direct Current Area) Internal Electronic Failure) is not output before removing or installing the HV battery. If this DTC is output, perform troubleshooting for this DTC first.
- To reduce the risk of electric shock, do not perform troubleshooting before checking for DTCs.
