Step	Inspection	Results	Action
1	IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA • Is the DTC P0500:00 on freeze frame data?	Yes	Go to the next step.
No	Go to the troubleshooting procedure for DTC on freeze frame data. (See DTC TABLE [PCM (SKYACTIV-X)].)
2	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.
3	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.
4	VERIFY ELECTRONICALLY CONTROLLED BRAKE UNIT DTC • Perform the DTC inspection for the electronically controlled brake unit. (See DTC INSPECTION.) • Are any DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [ELECTRONICALLY CONTROLLED BRAKE UNIT].)
No	Go to the next step.
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED • Install/connect the part removed/disconnected during the troubleshooting procedure. • 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. ― Access the ENG_RPM and LOAD_CALC PIDs using the M-MDS. (See PID/DATA MONITOR INSPECTION.) Warning • While performing this step, always operate the vehicle in a safe and lawful manner. • When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the M-MDS using the PID/DATA MONITOR AND RECORD capturing function and inspect later. ― Drive the vehicle under the following conditions for 14 s. • Neutral sensor No.1 does not determine neutral position (MTX) • Neutral sensor No.2 does not determine neutral position (MTX) • Clutch pedal released (MTX) • Shift position: except P or N position (ATX) • Absolute load: above 40 % • Engine speed: above 2,000 rpm • Brake switch: 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.

IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA

• Is the DTC P0500:00 on freeze frame data?

Yes

Go to the next step.

Go to the troubleshooting procedure for DTC on freeze frame data.

(See DTC TABLE [PCM (SKYACTIV-X)].)

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.

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.

Go to the next step.

VERIFY ELECTRONICALLY CONTROLLED BRAKE UNIT DTC

• Perform the DTC inspection for the electronically controlled brake unit.

(See DTC INSPECTION.)

• Are any DTCs displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

(See DTC TABLE [ELECTRONICALLY CONTROLLED BRAKE UNIT].)

Go to the next step.

Repair completion verification 1

VERIFY THAT VEHICLE IS REPAIRED

• Install/connect the part removed/disconnected during the troubleshooting procedure.

• 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.

― Access the ENG_RPM and LOAD_CALC PIDs using the M-MDS.

(See PID/DATA MONITOR INSPECTION.)

Warning

• While performing this step, always operate the vehicle in a safe and lawful manner.

• When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the M-MDS using the PID/DATA MONITOR AND RECORD capturing function and inspect later.

― Drive the vehicle under the following conditions for 14 s.

• Neutral sensor No.1 does not determine neutral position (MTX)

• Neutral sensor No.2 does not determine neutral position (MTX)

• Clutch pedal released (MTX)

• Shift position: except P or N position (ATX)

• Absolute load: above 40 %

• Engine speed: above 2,000 rpm

• Brake switch: 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].)

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.
