P112 HYBRID VEHICLE CONTROL: HYBRID CONTROL SYSTEM: P0A1D-568: Hybrid Powertrain Control Module

DTC P0A1D-568 - Hybrid Powertrain Control Module

DTC P0A1D-569 - Hybrid Powertrain Control Module

DESCRIPTION

The HV control ECU performs self-checks to detect an internal operating malfunction in the ECU.





MONITOR DESCRIPTION

The HV control ECU performs diagnostic monitoring to verify proper operation of internal and external ECU systems. In this diagnostics monitor, the HV control ECU checks the REF signal from the motor main ECU for errors.
If the HV control ECU detects an error in the REF signal, it will conclude that there is a malfunction in the motor main CPU, the REF signal or the HV control ECU. The HV control ECU illuminates the MIL and sets a DTC.
