- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the GTS off.
- Turn the ignition switch off.
- Disconnect the GTS.
- Disconnect the cable from the negative (-) auxiliary battery terminal and wait for 1 minute.
- Connect the cable to the negative (-) auxiliary battery terminal.
- Turn the ignition switch to ON.
- Wait for 1 second 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 / Transmission / Utility / All Readiness.
- Input the DTC: P061347.
- Check the DTC judgment result.
GTS 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 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.
CAUTION / NOTICE / HINT
NOTICE:
- Perform the universal trip to clear permanent DTCs.

- After turning the ignition switch off, waiting time may be required before
disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore,
make sure to read the disconnecting the cable from the negative (-) auxiliary
battery terminal notices before proceeding with work.

HINT:
Read Freeze Frame Data using the GTS. The TCM 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.
