DIAGNOSTIC PROCEDURE (DTC P0245)

Step		Check	Yes	No
1 CHECK OUTPUT SIGNAL FROM ECM. Turn the ignition switch to ON. Measure the voltage between ECM and chassis ground. Connector & terminal (B134) No. 32 (+) - Chassis ground (-):		Is the voltage more than 10 V?	Even if the malfunction indicator light illuminates, the circuit has returned to a normal condition at this time.	Go to step 2.
2 CHECK HARNESS BETWEEN WASTEGATE CONTROL SOLENOID VALVE AND ECM CONNECTOR. Turn the ignition switch to OFF. Disconnect the connectors from wastegate control solenoid valve and ECM. Measure the resistance in harness between wastegate control solenoid valve connector and engine ground. Connector & terminal (E64) No. 1 - Engine ground:		Is the resistance more than 1 M?	Go to step 3.	Repair the ground short circuit in harness between ECM and waste-gate control solenoid valve connector.
3 CHECK HARNESS BETWEEN WASTEGATE CONTROL SOLENOID VALVE AND ECM CONNECTOR. Measure the resistance of harness between wastegate control solenoid valve of harness connector and ECM. Connector & terminal (B134) No. 32 - (E64) No. 1:		Is the resistance less than 1 ?	Go to step 4.	Repair the open circuit in harness between ECM and wastegate control solenoid valve connector. NOTE: In this case, repair the following: Open circuit in harness between ECM and wastegate control solenoid valve connector
4 CHECK WASTEGATE CONTROL SOLENOID VALVE. Remove the wastegate control solenoid valve. Measure the resistance between wastegate control solenoid valve terminals. Terminals No. 1 - No. 2:		Is the resistance 30 - 34 ?	Go to step 5.	Replace the wastegate control solenoid valve. < Ref. to WASTEGATE CONTROL SOLENOID VALVE . >
5 CHECK POWER SUPPLY TO WASTEGATE CONTROL SOLENOID VALVE. Turn the ignition switch to ON. Measure the voltage between wastegate control solenoid valve and engine ground. Connector & terminal (E64) No. 2 (+) - Engine ground (-):		Is the voltage more than 10 V?	Go to step 6.	Repair the open circuit in harness between main relay and wastegate control solenoid valve connector.
6 CHECK POOR CONTACT. Check poor contact in wastegate control solenoid valve connector.		Is there poor contact in wastegate control solenoid valve connector?	Repair the poor contact in wastegate control solenoid valve connector.	Replace the ECM. < Ref. to ENGINE CONTROL MODULE (ECM) . >
