Mitsubishi Outlander XL. Manual - part 362

STEP 3. Check the trouble symptoms.

(1)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic  Function  -  OBD-II  Drive  Cycle  Pattern  17  P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P1238 set?

YES:

 Replace the ECM. When the ECM is replaced, register

the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 4.

NO:

 It can be assumed that this malfunction is

intermittent. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points - How to Cope
with Intermittent Malfunctions P.00-15.

STEP 4. Test the OBD-II drive cycle.

(1)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic  Function  -  OBD-II  Drive  Cycle  Pattern  17  P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P1238 set?

YES:

 Replace the troubleshooting.

NO:

 The procedure is complete.
