DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK OUTPUT SIGNAL OF ECM. Turn the ignition switch to ON. Measure the voltage between ECM and chassis ground. Connector & terminal (B134) No. 17 (+) - Chassis ground (-):	Is the voltage 10 V or more?	Go to step 2 .	Go to step 3 .
2 CHECK FOR POOR CONTACT. Check for poor contact of ECM connector.	Is there poor contact of ECM connector?	Repair the poor contact of ECM connector.	Even if DTC is detected, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again. NOTE: In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.
3 CHECK POWER SUPPLY TO THE INTAKE OIL CONTROL SOLENOID RH. Measure the voltage between intake oil control solenoid RH connector and engine ground. Connector & terminal (E38) No. 1 (+) - Engine ground (-):	Is the voltage 10 V or more?	Go to step 4 .	Repair the power supply circuit.
4 CHECK HARNESS BETWEEN ECM AND INTAKE OIL CONTROL SOLENOID RH CONNECTOR. Turn the ignition switch to OFF. Disconnect the connectors from the ECM and intake oil control solenoid RH. Measure the resistance between intake oil control solenoid RH connector and engine ground. Connector & terminal (E38) No. 2 - Engine ground:	Is the resistance 1 MΩ or more?	Go to step 5 .	Repair the short circuit to ground in harness between ECM and intake oil control solenoid RH connector.
5 CHECK HARNESS BETWEEN ECM AND INTAKE OIL CONTROL SOLENOID RH CONNECTOR. Measure the resistance of harness between ECM and intake oil control solenoid RH. Connector & terminal (B134) No. 17 - (E38) No. 2:	Is the resistance less than 1 Ω?	Go to step 6 .	Repair the harness and connector. NOTE: In this case, repair the following item: Open circuit in harness between ECM and intake oil control solenoid RH connector Poor contact of coupling connector
6 CHECK INTAKE OIL CONTROL SOLENOID RH. Measure the resistance between intake oil control solenoid RH terminals. Terminals No. 1 - No. 2:	Is the resistance 6 - 12 Ω?	Repair the poor contact of intake oil control solenoid RH connector.	Replace the intake oil control solenoid RH. Refer to OIL CONTROL SOLENOID .
