2GR-FXE ENGINE CONTROL: SFI SYSTEM: P062F: Internal Control Module EEPROM Error
P062F - Internal Control Module EEPROM Error

DESCRIPTION

The ECM monitors its internal operation and it stores this DTC when it detects an internal malfunction.





MONITOR DESCRIPTION

The ECM monitors its internal operation. If the internal operation is malfunctioning, the ECM illuminates the MIL and stores a DTC.

TYPICAL MALFUNCTION THRESHOLDS





CONFIRMATION DRIVING PATTERN

1. Connect the Techstream to the DLC3.

2. Turn the power switch on (IG) and turn the Techstream on.

3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

4. Turn the Techstream off.

5. Turn the power switch off.

6. Disconnect the Techstream.

7. Disconnect the cable from the negative (-) auxiliary battery terminal and wait for 1 minute.

8. Connect the cable to the negative (-) auxiliary battery terminal.

9. Connect the Techstream to the DLC3.

10. Turn the power switch on (IG) and turn the Techstream on.

11. Put the engine in inspection mode Component Tests and General Diagnostics.

12. Start the engine and wait 30 seconds or more.

13. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

14. Read the pending DTCs.

HINT
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.

15. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

16. Input the DTC: P062F.

17. 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.

18. If the judgment result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for permanent DTCs Reading and Clearing Diagnostic Trouble Codes.

HINT
- If a permanent DTC is output, the system is malfunctioning.
- If no permanent DTC is output, the system is normal.

INSPECTION PROCEDURE

NOTICE:
- There is a possibility that the DTC P062F is issued from the ECUs of the EFI and HV ECU.
Use Techstream to conduct a health check to confirm which ECU the DTC is issued from and then inspect the related system.
- w/ HDD Navigation System
After the power switch is turned off, the display and navigation module display (HDD navigation system) records various types of memory and settings. As a result, after tuning the power switch off, make sure to wait 60 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal.

HINT
Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE

1. READ OUTPUT DTC (DTC P062F)

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Turn the Techstream on.

(d) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.

(e) Turn the power switch off and turn the Techstream off.

(f) Disconnect the Techstream.

(g) Disconnect the cable from the negative (-) auxiliary battery terminal and wait for 1 minute.

(h) Connect the cable to the negative (-) auxiliary battery terminal.

(i) Connect the Techstream to the DLC3.

(j) Turn the power switch on (IG).

(k) Turn the Techstream on.

(l) Put the engine in inspection mode Component Tests and General Diagnostics.

(m) Start the engine and wait 30 seconds or more.

(n) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

(o) Read the DTCs.
