DESCRIPTION The ECM monitors its internal operation and it stores this DTC when it detects an internal malfunction. |
DTC No. | DTC Detection Condition |
Trouble Area | | P062F |
An ECM internal error (EEPROM). (1 trip detection logic) |
ECM | MONITOR DESCRIPTION
The
ECM monitors its internal operation. If the internal operation is
malfunctioning, the ECM illuminates the MIL and stores a DTC. MONITOR STRATEGY |

- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON and turn the Techstream on.
- Clear DTCs (even if no DTCs are stored, perform the clear DTC operation).
- Turn the ignition switch off and wait for at least 30 seconds.
- Turn the ignition switch to ON and turn the Techstream on.
- Wait 30 seconds or more.
- Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
- 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.
- Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
- Input the DTC: P062F.
- Check the DTC judgment result.

Tester Display |
Description |
|
NORMAL |
- DTC judgment completed
- System normal
|
|
ABNORMAL |
- DTC judgment completed
- System abnormal
|
|
INCOMPLETE |
- DTC judgment not completed
- Perform driving pattern after confirming DTC enabling conditions
|
|
N/A |
- Unable to perform DTC judgment
- Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit
|
HINT:
If the judgment result shows ABNORMAL, the system has a malfunction.
- If the test result is INCOMPLETE or N/A and no pending DTC is output,
perform a universal trip and check for permanent DTCs (See page
 ).
HINT:
- If a permanent DTC is output, the system is malfunctioning.
- If no permanent DTC is output, the system is normal.
CAUTION / NOTICE / HINT NOTICE: After
turning ignition switch off, waiting time may be required before
disconnecting the cable from the negative (-) battery terminal.
Therefore, make sure to read the disconnecting the cable from the
negative (-) battery terminal notices before proceeding with work (See
page ). HINT:
Read
freeze frame data using a Techstream. Freeze frame data record the
engine condition when malfunctions are detected. 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
