EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE EC-1201 < DTC/CIRCUIT DIAGNOSIS > [MR EXCEPT FOR NISMO RS MODELS] C D E F G H I J K L M A EC N P O EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE Component Function Check INFOID:0000000012198733 1. CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE FUNCTION With CONSULT 1. Turn ignition switch OFF. 2. Disconnect the EVAP purge hose from EVAP canister purge volume control solenoid valve (EVAP canis- ter side). 3. Start engine and let it idle. 4. Select “PURG VOL CONT/V” in “ACTIVE TEST” mode wit CONSULT. 5. Touch “Qu” and “Qd” on CONSULT screen to adjust “PURG VOL CONT/V” and check vacuum existence under the following conditions. Without CONSULT 1. Turn ignition switch OFF. 2. Disconnect the EVAP purge hose from EVAP canister purge volume control solenoid valve (EVAP canis- ter side). 3. Start engine and let it idle for at least 100 seconds. 4. Check vacuum existence under the following conditions. Is the inspection result normal? YES >> INSPECTION END NO >> Proceed to EC-1201, "Diagnosis Procedure" . Diagnosis Procedure INFOID:0000000012198734 1. CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE POWER SUPPLY 1. Turn ignition switch OFF. 2. Disconnect EVAP canister purge volume control solenoid valve harness connector. 3. Turn ignition switch ON. 4. Check the voltage between EVAP canister purge volume control solenoid valve harness connector and ground. Is the inspection result normal? YES >> GO TO 3. NO >> GO TO 2. 2. CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT 1. Turn ignition switch OFF. 2. Disconnect IPDM E/R harness connector. 3. Check the continuity between EVAP canister purge volume control solenoid valve harness connector and IPDM E/R harness connector.
