P0A1F / INF593

DTC P0A1F-593 Battery Energy Control Module

DESCRIPTION

DTC Detection Condition:

The battery ECU transmits information on the IG2 voltage of the battery ECU to the HV control ECU via CAN communication.

MONITOR DESCRIPTION

Monitor Strategy:

Typical Enabling Conditions:

Typical Malfunction Thresholds:

Component Operating Range:

When the IG2 voltage of the battery ECU, which is transmitted while the power switch is ON (IG), is low, the HV control ECU determines that a wiring malfunction has occurred at the IG2 terminal of the battery ECU. When the HV control ECU detects the malfunction, it illuminates the MIL and sets a DTC.
