Diagnostic Procedure

Step

Inspection

Results

Action

1

RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION

•  Record the freeze frame data/snapshot data.

Note

•  Recording can be facilitated using the screen capture function of the PC.

—

Go to the next step.

2

VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY

•  Verify related Service Bulletins, on-line repair information, or Service Information availability.

•  Is any related Information available?

Yes

Perform repair or diagnosis according to the available information.

•  If the vehicle is not repaired, go to the next step.

No

Go to the next step.

3

ALLOW THE VEHICLE TO COOL DOWN FOR WHILE

•  Switch the ignition to off and allow vehicle to cool down.

—

Go to the next step.

4

INSPECT TRANSFER FOR MALFUNCTION

•  Shift the selector lever to the N position.(ATX)

•  Shift the shift lever to the neutral position.(MTX)

•  Lift up the vehicle.

•  Turn the propeller shaft and rotate the front wheels.

•  Do the front wheels rotate smoothly?

Yes

Go to the next step.

No

Repair or replace the malfunctioning location and perform the repair completion verification.

(See TRANSFER REMOVAL/INSTALLATION [C66MX-R (SKYACTIV-X 2.0)].)

(See TRANSFER REMOVAL/INSTALLATION [ET6AX-EL (SKYACTIV-X 2.0)].)

5

INSPECT COUPLING COMPONENT AND REAR DIFFERENTIAL FOR MALFUNCTION

•  Shift the selector lever to the N position.

•  Connect the M-MDS to the DLC-2.

•  Switch the ignition ON (engine off).

•  Access the following simulation item using the M-MDS:

―   CUP_SOL

•  Lift up the vehicle.

•  Turn the simulation item CUP_SOL on and turn the AWD solenoid on.

•  Turn the propeller shaft and rotate the rear wheels.

•  Do the rear wheels rotate smoothly?

Yes

Go to the next step.

No

Repair or replace the malfunctioning location and perform the repair completion verification.

(See COUPLING COMPONENT REMOVAL/INSTALLATION [(E)].)

(See REAR DIFFERENTIAL REMOVAL/INSTALLATION [(E)].)

Repair completion verification 1

VERIFY THAT VEHICLE IS REPAIRED

•  Clear the DTC recorded in the memory.
(See CLEARING DTC.)

•  Replicate the vehicle conditions at the time the DTC was detected using the following procedure.

―  Switch the ignition ON (engine off)

•  Perform the DTC inspection for the PCM.
(See DTC INSPECTION.)

•  Is the same Pending DTC present?

Yes

Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.

(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].)

If the CAN communication is normal, perform the diagnosis from Step 1.

•  If the malfunction recurs, replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [SKYACTIV-X 2.0].)

No

Go to the next step.

Repair completion verification 2

VERIFY IF OTHER DTCs DISPLAYED

•  Perform the DTC inspection.
(See DTC INSPECTION.)

•  Are any other DTCs displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

No

DTC troubleshooting completed.
