- УКАЗАНИЕ:
- These DTCs are set when the engine idles for approximately 60 seconds.
- When DTC P0252 and/or P1228 is set, check the internal fuel pressure of the common rail by selecting the following menu items on the intelligent tester: Powertrain / Engine and ECT / Data List / Common Rail Pressure.
Engine Speed
| Fuel Pressure
|
Idling
| Approximately 25 to 36 MPa
|
2000 rpm (No engine load)
| Approximately 27 to 46 MPa
|
3000 rpm (No engine load)
| Approximately 34 to 69 MPa

INSPECTION PROCEDURE
- УКАЗАНИЕ:
- Read freeze frame data using an intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
1.READ OUTPUT DTCS (DTC P0252 AND/OR P1228) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch to the ON position.
Turn the tester on.
Enter the following menu items: Powertrain / Engine and ECT / DTC.
Read the DTCs.
