Monitor Description

The HV control ECU performs diagnostic monitoring to verify proper operation of internal and external ECU systems. In this diagnostic monitor, the HV control ECU checks for an R/D (Resolver / Digital Converter) malfunction involving the motor resolver.

If the HV control ECU detects an R/D error, it will conclude that there is an internal malfunction involving the motor resolver. The HV control ECU will illuminate the MIL and set a DTC.
