Lexus ES: Generator Control Module(EEPROM Learning Value) Calibration / Parameter Memory Failure (P062F46)
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 |
|---|---|---|---|---|---|
| P062F46 | Generator Control Module(EEPROM Learning Value) Calibration / Parameter Memory Failure | ECU internal malfunction (EEPROM error) (1 trip detection logic) | Inverter with converter assembly | Comes on | Master Warning Light: Comes 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.
MONITOR STRATEGY

-
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- 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 15 seconds or more. [*1]
HINT:
[*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.
PROCEDURE
| 1. | CHECK DTC OUTPUT (HEALTH CHECK) |
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Enter the following menus: System Select / Health Check.
(d) Check for DTCs.
| Result | Proceed to |
|---|---|
| P062F46 is output from the motor generator control system. | A |
| P062F46 is output from any system other than the motor generator control system. | B |
(e) Turn the power switch off.
