CONFIRMATION DRIVING PATTERN
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG).
- Turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the Techstream off.
- Turn the power switch off.
- Disconnect the Techstream.
- Disconnect the cable from the negative (-) auxiliary battery terminal and wait for 1 minute.
- Connect the cable to the negative (-) auxiliary battery terminal.
- Connect the Techstream to the DLC3.
- Start the engine and wait 30 seconds or more.
- Turn the Techstream on.
- Enter the following menus: Powertrain / Engine / 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 / Utility / All Readiness.
- Input the DTC: P062F44.
-
Check the DTC judgment result.
Techstream Display
Description
NORMAL
ABNORMAL
- DTC judgment completed
- System abnormal
INCOMPLETE
- DTC judgment not completed
- Perform driving pattern after confirming DTC enabling conditions
HINT:
- If the judgment result is NORMAL, the system is normal.
- If the judgment result is ABNORMAL, the system is malfunctioning.
CAUTION / NOTICE / HINT
NOTICE:
-
After turning power 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.

Vehicle Control History may be stored in the hybrid vehicle control ECU assembly if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the freeze frame data and Vehicle Control History can be useful for troubleshooting.

(Select Powertrain in Health Check and then check the time stamp data.)

-
If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU assembly, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.

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. |
CLEAR DTC |
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Clear the DTCs.
Powertrain > Engine > Clear DTCs
(e) Turn the power switch off.
|
|
2. |
READ OUTPUT DTC (DTC P062F44) |
(a) Disconnect the cable from the negative (-) auxiliary battery terminal and wait for 1 minute.
(b) Connect the cable to the negative (-) auxiliary battery terminal.
(c) Connect the Techstream to the DLC3.
(d) Start the engine and wait 30 seconds or more.
(e) Turn the Techstream on.
(f) Enter the following menus: Powertrain / Engine / Trouble Codes.
(g) Read the DTCs.
Powertrain > Engine > Trouble Codes
