Component Inspection
CANISTER DRAIN CUT VALVE (CDCV) INSPECTION
Simulation Test
1. Carry out the "Evaporative Emission (EVAP) Control System Inspection". (See Evaporative Emission (EVAP) System Leak Inspection Using
Vacuum Pump.)
-
If not as specified, perform the further inspection for the CDCV.
Airflow Inspection
NOTE: Perform the following test only when directed.
1. Remove the CDCV.
2. Inspect airflow between the ports under the following conditions.
-
If as specified but the "Evaporative Emission (EVAP) Control System Inspection" is failed, inspect evaporative hoses for improper routing,
kinks or leakage, and inspect "Circuit Open/Short Inspection".
-
If not as specified, replace the CDCV.
Circuit Open/Short Inspection
Open circuit
-
GND circuit (CDCV connector terminal B and PCM connector terminal 3E through common connector)
-
Power circuit (CDCV connector terminal A and main relay connector terminal D)
Short circuit
-
CDCV connector terminal B and PCM connector terminal 3E to GND
