NOTE

:
If DTC P245A is displayed with DTC P0560 or P0657, first perform trouble diagnosis for DTC P0560 or P0657.

Refer to EC-963, "DTC Logic" (DTC P0560) or EC-976, "DTC Logic" (DTC P0657).

Diagnosis Procedure

1.CHECK GROUND CONNECTIONS

1. Turn ignition switch OFF.

2. Check ground connection E38. Refer to Ground inspection in GI-44, "Circuit Inspection".

Is the inspection result normal? YES >> GO TO 2.

NO >> Repair or replace ground connection.

2.CHECK EGR COOLER BYPASS VALVE CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect EGR cooler bypass valve control solenoid valve harness connector.

3. Turn ignition switch ON.

4. Check the voltage between EGR cooler bypass valve control solenoid valve harness connector and ground.

Is the inspection result normal?


Is the inspection result normal? YES >> GO TO 4.

NO >> GO TO 3.

3.DETECT MALFUNCTIONING PART

Check the following.

• Harness connectors E8, F1 • Harness for open or short between IPDM E/R and EGR cooler bypass valve control solenoid valve

>> Repair open circuit or short to ground or short to power in harness or connectors.

4.CHECK EGR COOLER BYPASS VALVE CONTROL SOLENOID VALVE GROUND CIRCUIT FOR OPEN AND SHORT

1. Turn ignition switch OFF.

2. Disconnect ECM harness connectors.

3. Check the continuity between EGR cooler bypass valve control solenoid valve harness connector and ECM harness connector.

4. Also check harness for short to ground and short to power.


4. Also check harness for short to ground and short to power.

Is the inspection result normal? YES >> GO TO 5.

NO >> Repair open circuit or short to ground or short to power in harness or connectors.

5.CHECK EGR COOLER BYPASS VALVE CONTROL SOLENOID VALVE

Refer to EC-1007, "Component Inspection".

Is the inspection result normal? YES >> GO TO 6.

NO >> Replace EGR cooler bypass valve control solenoid valve.

6.CHECK INTERMITTENT INCIDENT

Refer to GI-42, "Intermittent Incident".

>> INSPECTION END

Component Inspection

1.CHECK EGR COOLER BYPASS VALVE CONTROL SOLENOID VALVE

1. Reconnect all harness connectors disconnected.

2. Measure the voltage signal between ECM harness connector and ground under the following conditions.

Is the inspection result normal?


Is the inspection result normal? YES >> INSPECTION END

NO >> Replace EGR cooler bypass valve control solenoid valve.
