DTC DETECTION LOGIC

POSSIBLE CAUSE

• Electric oil pump
• Secondary pressure sensor

FAIL-SAFE

• Restart the engine during the stop/start system operation
• Turn OFF the electric oil pump relay
• When the vehicle is in stop/start system operation and the engine stops, restart the engine immediately

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 (PART 1)

With CONSULT
