DTC SUMMARY
MALFUNCTION DESCRIPTION
These DTCs indicate an abnormal resolver output signal. The cause of this malfunction may be one of the following:
Internal inverter malfunctionHINT:
If any of these DTCs is output, a malfunction of the MG ECU circuit board or poor installation of a low voltage connector is suspected. It is not necessary to inspect the motor resolver.

MONITOR DESCRIPTION
The motor generator control ECU monitors the Generator resolver output signal. If the motor generator control ECU detects output signals that are out of the normal range or specification, it will conclude that there is a malfunction in the Generator resolver. If a malfunction is detected, the motor generator control ECU will illuminate the MIL and store a DTC.
