Code No. P252F: Engine Oil Level Malfunction <Vehicles with closed type DPF>

FUNCTION

The engine oil level may ascend if the fuel runs into the engine oil on the DPF regeneration.
The engine-ECU monitors the engine driving conditions to estimate the ascend of engine oil level.

TROUBLE JUDGMENT

Check Condition

Ignition switch is in "ON" position.

Judgement Criterion

The estimated increased amount of the engine oil exceeds the 1,000 cc.

PROBABLE CAUSE

The engine oil is increased.

DIAGNOSIS PROCEDURE

STEP 1. Replace the engine oil.

Replace the engine oil, When the engine oil is replaced, initialise the learning value (Refer to GROUP 00 - Precautions before Service - Initialisation Procedure for Learning Value in Diesel Particulate Filter (DPF) System ). After initialising the learning value, reconfirm diagnosis code.

Q. Is the diagnosis code set?

Replace the engine-ECU. When the engine-ECU is replaced, write the chassis number (Refer to GROUP 00 - Precautions Before Service - How to Perform Chassis Number Writing

). After replacing the engine-ECU, register the injector identification code and learn fuel injection (Refer to GROUP 00 - Precautions Before Service - What The Common Rail Engine Learns

). After registering the injector identification code, carry out the forcible DPF regeneration (Refer to GROUP 17 - Diesel Particulate Filter (DPF) System - Forcible DPF Regeneration
