NOTE:
DC stands for “DRIVING CYCLE” and indicates a series of driving cycle of “Ignition switch OFF
→
ON
→
driv-
ing
→
OFF”.

• Harness or connector (G sensor circuit)
• G sensor
FAIL-SAFE
• Stop/start system prohibited
• Restart the engine during the stop/start system operation
• Turn OFF the electric oil pump relay
DTC CONFIRMATION PROCEDURE
CAUTION:
Be careful of the driving speed.
1.
PREPARATION BEFORE WORK
If another “DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at
least 10 seconds, then perform the next test.
>> GO TO 2.
2.
CHECK DTC DETECTION
With CONSULT
1.
Start the engine.
2.
Drive the vehicle for 5 seconds or more.
3.
Stop the vehicle.
CAUTION:
Never stop the engine.
4.
Repeat step 2 through 3.
5.
Check the DTC.
