Purge Control System Inspection<\/p>\n


<\/p>\n

<\/a><\/p>\n

Without Using the M-MDS<\/p>\n

1.Start the engine and idle it.<\/p>\n

\n

2.Remove the plug hole plate. (See PLUG HOLE PLATE REMOVAL\/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))]<\/a>.)<\/p>\n

\n

3.Disconnect the evaporative hose between the purge solenoid valve and the charcoal canister.<\/p>\n

\n

4.While idling the engine when cold, verify that vacuum is not applied by touching the purge solenoid valve with your finger as shown in the figure.<\/p>\n

5.Load the vehicle on the chassis dynamometer and drive it while maintaining the engine speed at approx. 2,000 rpm.<\/p>\n

\n

\n
\n
Warning<\/div>\n<\/dd>\n
\n
\u2022 When using a chassis dynamometer, be careful not to get parts such as tires or rollers caught in the rotating parts.<\/div>\n<\/dd>\n<\/dl>\n

6. Verify that vacuum is applied after approx. 30 s.<\/span><\/p>\n

<\/p>\n

<\/a><\/p>\n

Using The M-MDS<\/p>\n

1.Connect the M-MDS to the DLC-2.<\/p>\n

\n

2.Start the engine and idle it.<\/p>\n

\n

3.Remove the plug hole plate. (See PLUG HOLE PLATE REMOVAL\/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))]<\/a>.)<\/p>\n

\n

4.Disconnect the evaporative hose between the purge solenoid valve and the charcoal canister.<\/p>\n

\n

6.Connect the evaporative hose.<\/p>\n

\n

7.When the 0% duty value of the purge solenoid valve is operated at a 100% duty value using the simulation function [PRG_DUTY], verify that the PID [SHRT_FUEL_TRIM11] value fluctuates.(See SIMULATION INSPECTION<\/a>.)<\/p>\n

\n

\n
\n
\u2022 If the PID [SHRT_FUEL_TRIM11] value does not change, inspect the following.<\/div>\n
\n
\n
1. Switch the ignition OFF.<\/div>\n
2. Switch the ignition ON (engine off).<\/div>\n
3. When the 0% duty value of the purge solenoid valve is operated at a 50% duty value using the simulation function [PRG_DUTY], verify the operation sound of the purge solenoid valve. (See SIMULATION INSPECTION<\/a>.)<\/div>\n<\/dd>\n<\/dl>\n<\/dd>\n<\/dl>\n
\n
\n
\u2022 If the operation sound can be verified, inspect the following.<\/div>\n
\n
\n
\u2015 Evaporative hose disconnection or damage (between intake manifold and purge solenoid valve, and purge solenoid valve and charcoal canister)<\/div>\n<\/dd>\n<\/dl>\n<\/dd>\n<\/dl>\n
\n
\n
\u2022 If the operation sound cannot be verified, inspect the following.<\/div>\n

\u2015 Open circuit in wiring harnesses and connectors (between main relay terminal and purge solenoid valve terminal B, purge solenoid valve terminal A and PCM terminal 1AW)<\/div>\n<\/dd>\n<\/dl>\n<\/dd>\n<\/dl>\n
\n
\n
Warning<\/div>\n<\/dd>\n
\n
\n
\u2022 When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the M-MDS using the PID\/DATA MONITOR AND RECORD capturing function and inspect later.<\/div>\n
\u2022 While performing this step, always operate the vehicle in a safe and lawful manner.<\/div>\n<\/div>\n<\/dd>\n<\/dl>\n

8.Drive the vehicle at an engine speed of approx. 2,000 rpm for 30 s or more.<\/p>\n

\n

9.Verify that the PID [PRG_DUTY] value fluctuates between 0% and 100%.<\/p>\n

\n

\n
\n
\u2022 If the PID [PRG_DUTY] value fluctuation cannot be verified, inspect the following and repair or replace the malfunctioning location.<\/div>\n
