Wiring Diagram

DTC Detecting Condition and Trouble Area

DTC Confirmation Procedure

1) With ignition switch OFF, connect scan tool to DLC.
2) Turn ON ignition switch and clear DTC using scan tool.
3) Start engine and warm up normal operating temperature.
4) Run engine at idle speed for 3 min. or more.
5) Check DTC.

I5JB0A110064-02

1. IMT vacuum solenoid valve

4. Fuse box No.2

7. “FI” fuse

2. Main relay

5. Ignition switch

8. “IGN” fuse

3. “IG COIL” fuse

6. ECM

DTC detecting condition

Trouble area

Monitor signal of IMT vacuum solenoid valve is different from
command signal. (Circuit open or short)
(1 driving cycle detection logic but MIL does not light up)

• IMT vacuum solenoid valve
