Diagnostic ProcedureEBS01145
1. CHECK OVERALL FUNCTION
With CONSULT-II
1. Turn ignition switch OFF.
2. Disconnect the EVAP purge hose connected to the EVAP canister.
3. Turn ignition switch ON, and select “PURG VOL CONT/V” in
“ACTIVE TEST” mode with CONSULT-II.
4. Start engine and let it idle.
5. Change the valve opening percentage with touching “Qu” or
“Qd” on CONSULT-II screen, and check for vacuum existence at
the EVAP purge hose under the following conditions.
Without CONSULT-II
1. Turn ignition switch OFF.
2. Disconnect the EVAP purge hose connected to the EVAP canis-
ter.
3. Start engine and let it idle for at least 80 seconds.
4. Check for vacuum existence at the EVAP purge hose under the
following conditions.
OK or NG
OK >> GO TO 2.
NG >> GO TO 3.
2. CHECK EVAP CANISTER
