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

MONITOR DESCRIPTION
The motor generator control ECU monitors the rear motor 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 rear motor resolver. If a malfunction is detected, the motor generator control ECU will illuminate the MIL and store a DTC.
