DTC |
P062F44 |
Hybrid/EV Powertrain Control Module EEPROM Data Memory Failure |
DESCRIPTION
The hybrid vehicle control ECU assembly monitors its internal operation and will store these DTCs when it detects an internal malfunction. If these DTCs are output, replace the hybrid vehicle control ECU assembly.

-
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off and wait for 2 minutes or more.
- Turn the ignition switch to ON and turn the Techstream on.
-
With ignition switch to ON 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 / Hybrid Control / 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, perform the normal judgment procedure again.
CAUTION / NOTICE / HINT
NOTICE:
There is a possibility that the DTC P062F44 is issued from the ECUs of the ECM and hybrid vehicle control ECU assembly. Use Techstream to conduct a health check to confirm which ECU the DTC is issued from and then inspect the related system.
PROCEDURE
|
1. |
CHECK DTC OUTPUT (HEALTH CHECK) |
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: System Select / Health Check.
(e) Check for DTCs.
