If simulation function of M-MDS is used
- Start the engine.
- Disconnect the vacuum hose between the purge solenoid valve and the charcoal canister.
- Put a finger to the purge solenoid valve and verify that there is no vacuum applied when the engine is cold.
- If there is a vacuum, inspect the following:
- Verify that the DTC P0443:00 is displayed. (See ON-BOARD DIAGNOSTIC TEST
.)
- If the DTC P0443:00 is shown, perform the DTC inspection. (See DTC P0443:00
.)
- Access the EVAPCP PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST
.)
- Put a finger to the purge solenoid valve with Step 2 condition and verify that there is vacuum applied when set the present to 100%
duty value of the purge solenoid valve using the EVAPCP PID simulation function.
- If there is no vacuum, inspect the following:
- Increase the duty value of the purge solenoid valve to 50%
and inspect if the operation sound of the valve is heard.
- If the operation sound is heard, inspect for loose or damaged vacuum hoses. (Intake manifold-Purge solenoid valve-Charcoal canister)
- If the operation sound is not heard, inspect the purge solenoid valve. (See PURGE SOLENOID VALVE INSPECTION
.)
- Warm up the engine to normal operating temperature.
- Monitor the EVAPCP PID using the M-MDS, and drive the vehicle approx. 2000 rpm
for 30 s or more
.
- If the EVAPCP PID is 0%
, inspect the following.
