DTC P0500:00 [PCM (SKYACTIV-D)]

id0102t5704800

Outline

System malfunction location

VSS circuit problem

Detection condition

•  With the following conditions met, a condition has continued for 5 s in which an error signal from the DSC HU/CM is received or no signal can be received from the DSC HU/CM.

―  Battery voltage: Exceeds 10 V.

―  1.5 s have elapsed after ignition is switched ON (engine off or on)

Fail-safe

•  PCM restricts engine torque.

•  Inhibits the DENOx/DESOx control.

•  Inhibits the diesel particulate filter regeneration control.

•  Inhibits the EGR control.

•  Inhibits engine-stop by operating the i-stop function.

Possible cause

•  Malfunction in CAN communication line between PCM and DSC HU/CM

•  DSC HU/CM malfunction

•  DSC HU/CM connector or terminal malfunction

•  ABS wheel-speed sensor malfunction

•  PCM malfunction

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

VERIFY THAT NO DTCs ARE STORED IN DSC HU/CM

•  Verify that no DTCs are stored in the DSC HU/CM.
(See DTC INSPECTION.)

•  Has any DTC been stored?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

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

No

Inspect the DSC HU/CM connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection.

Repair or replace the malfunctioning location, then 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.

―  Leave for 10 s while idling.

•  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-D 1.8].)

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.
