System Wiring Diagram

• Not applicable

Function Explanation (DTC Detection Outline)

• The PCM monitors the oil level while the above preconditions are being met and if the traveled distance is 100 km {62.2 mph} or more or the monitoring time is 30 s or more, it calculates the average oil level.

• If the averaged oil level is near the X mark two times in a row, the PCM stores a DTC and turns on the wrench indicator light in the instrument cluster.

Repeatability Verification Procedure

1. Move the vehicle to a level area and switch the ignition ON.

2. Verify engine oil level using the dipstick (verify that it is near the X mark).

STEP	INSPECTION		ACTION
1	PURPOSE: RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION Note • Recording can be facilitated using the screen capture function of the PC. • Record the snapshot data on the repair order.	—	Go to the next step.
2	PURPOSE: VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	PURPOSE: IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA • Is the DTC P252F:00 on FREEZE FRAME DATA?	Yes	Go to the next step.
3		No	Go to the troubleshooting procedure for DTC on FREEZE FRAME DATA. (See DTC TABLE [SKYACTIV-D 1.5].)
4	PURPOSE: VERIFY IF DIAGNOSTIC RESULT IS AFFECTED BY OTHER RELATED DTCs OCCURRING • Switch the ignition off, then ON (engine off). • Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].) • Is the other PENDING CODE/DTC also present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-D 1.5].)
4		No	Go to the next step.
5	PURPOSE: VERIFY IF THERE IS PID ITEM CAUSING DRASTIC CHANGES OF ACCELERATION FLUCTUATION BY INPUT SIGNAL TO PCM • Access the following PIDs using the M-MDS: (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].) PCM: ― EOL • Is there any signal that is far out of specification?	Yes	Go to the next step.
5		No	Go to the troubleshooting procedure to perform the procedure from Step 1.
6	PURPOSE: VERIFY CONNECTOR CONNECTIONS • Access the following PIDs using the M-MDS: (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].) PCM: ― EOL • When the following parts are shaken, does the PID value include a PID item which has changed? ― Engine oil level sensor ― PCM	Yes	Repair or replace the applicable connector parts. Go to the troubleshooting procedure to perform the procedure from Step 3.
6		No	Go to the troubleshooting procedure to perform the procedure from Step 1.

Troubleshooting Diagnostic Procedure

Intention of troubleshooting procedure

• Step 1

― Perform inspection of engine oil level.

• Step 2

― Inspect for clogging of the oil passage to the engine oil level sensor detection area.

• Step 3—4

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

STEP

INSPECTION

ACTION

Replace the engine oil.

(See ENGINE OIL REPLACEMENT [SKYACTIV-D 1.5].)

Perform the “ENGINE OIL DATA RESET”, then go to Step 3.

(See ENGINE OIL DATA RESET [SKYACTIV-D 1.5].)

No

Go to the next step.

2

PURPOSE: INSPECT FOR CLOGGING OF THE OIL PASSAGE TO THE ENGINE OIL LEVEL SENSOR DETECTION AREA

•  Remove the engine oil level sensor.
(See ENGINE OIL LEVEL SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)

•  Visually inspect the oil passage to the engine oil level sensor.

•  Is there any restriction detected?

Yes

Clean the oil passage, then go to the next step.

No

Replace the engine oil level sensor, then go to the next step.

(See ENGINE OIL LEVEL SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)

3

PURPOSE: PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING PART IS PCM

•  Always reconnect all disconnected connectors.

•  Clear the DTC from the PCM memory using the M-MDS.
(See CLEARING DTC [SKYACTIV-D 1.5].)

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

•  Perform the DTC Reading Procedure.
(See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].)

•  Is the same DTC present?

Yes

Repeat the inspection from Step 1.

•  If the malfunction recurs, replace the PCM.
(See PCM REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)

Go to the next step.

No

Go to the next step.

4

PURPOSE: VERIFY AFTER REPAIR PROCEDURE
