DESCRIPTION
The inverter with converter assembly monitors its internal operation and will store this DTC if it detects a malfunction of its EEPROM.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
P062F44 | Internal Control Module EEPROM Data Memory Failure | ECU internal malfunction (EEPROM error) (1 trip detection logic) | Inverter with converter assembly | Comes on | Master Warning Light: Does not come on |
MONITOR DESCRIPTION
The motor generator control ECU monitors its internal operation. If the internal operation is malfunctioning, the motor generator control ECU illuminates the MIL and stores a DTC.

[*1]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
-
Enter the following menus: Powertrain / Motor Generator / Utility / All Readiness.
-
Check the DTC judgment result.
HINT:
-
If the judgment result shows NORMAL, the system is normal.
-
If the judgment result shows ABNORMAL, the system has a malfunction.
-
If the judgment result shows INCOMPLETE or N/A, perform the normal judgment procedure again.
