Lexus NX: Internal Control Module EEPROM Error (P062F-489)
DESCRIPTION
The hybrid vehicle control ECU monitors its internal operation and will store the DTC when it detects an internal malfunction.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
|---|---|---|---|---|---|
| P062F-489 | Internal Control Module EEPROM Error | ECU internal malfunction (1 trip detection logic) | Hybrid vehicle control ECU | Comes on | Master Warning Light: Comes on |
MONITOR DESCRIPTION
The hybrid vehicle control ECU monitors its internal operation. If the internal operation is malfunctioning, the hybrid vehicle control ECU illuminates the MIL and stores a DTC.

TYPICAL MALFUNCTION THRESHOLDS
| TMC's intellectual property | - |
COMPONENT OPERATING RANGE
| Hybrid vehicle control ECU | DTC P062F (INF 489) is not detected |
CONFIRMATION DRIVING PATTERN
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG) and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the power switch off. and wait for 2 minutes or more.
- Turn the power switch on (IG) and turn the Techstream on.
- With power switch on (IG) and wait for 30 seconds or more.
- Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
-
Read the current DTCs.
HINT:
- If a current DTC is output, the system is malfunctioning.
- If a current DTC is not output, perform the following procedure.
- Check that permanent DTCs are cleared. If no permanent DTC is output, the system is normal.
- If the permanent DTCs are not cleared, perform the universal trip, and then check for permanent DTCs again.
