System Wiring Diagram

• Not applicable

Function Explanation (DTC Detection Outline)

• The PM sensor performs diagnosis independently and if it detects that the internal heater is operating, it sends a malfunction signal to the PCM.

• When the malfunction signal is received from PM sensor, the PCM stores a DTC.

Repeatability Verification Procedure

1. Start the engine and leave it idling for 30 s.

Inspection

Results

Action

1

PURPOSE: 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.

2

PURPOSE: IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA

•  Is DTC P24B3:00 causing the 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-D)].)

3

PURPOSE: RECORD FREEZE FRAME DATA/SNAPSHOT DATA AND DIAGNOSTIC MONITORING TEST RESULTS TO UTILIZE WITH REPEATABILITY VERIFICATION

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

•  Record the FREEZE FRAME DATA/snapshot data and DIAGNOSTIC MONITORING TEST RESULTS (PM sensor related) on the repair order.

Troubleshooting Diagnostic Procedure

Intention of troubleshooting procedure

• Step 1—2

― Perform inspection of PM sensor signal related parts.

• Repair completion verification

― Verify that the primary malfunction is resolved and there are no other malfunctions.

Step

Inspection

Results

Action

1

PURPOSE: INSPECT PM SENSOR CONNECTOR FOR MALFUNCTION

•  Inspect the applicable connector and terminal.
(See CONNECTOR INSPECTION.)

•  Are the connector and terminal normal?

Yes

Go to the next step.

No

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

2

PURPOSE: INSPECT PCM CONNECTOR FOR MALFUNCTION

•  Inspect the applicable connector and terminal.
(See CONNECTOR INSPECTION.)

•  Are the connector and terminal normal?

Yes

Go to the next step.

No

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

Repair completion verification 1

PURPOSE: 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.

―  Implement the repeatability verification procedure.
(See Repeatability Verification Procedure)

•  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

PURPOSE: 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.
