CAUTION:

• Do not use compressed air or a high pressure pump.
• Do not exceed 4.12 kPa (0.042 kg/cm

2

, 0.6 psi) of pressure in EVAP system.

NOTE:

• Do not start engine.

• Improper installation of EVAP service port adapter [commercial service tool: (J-41413-OBD)] to the EVAP

service port may cause a leak.

1.

EVAP LEAK CHECK

With CONSULT

1. Install EVAP service port adapter [commercial service tool: (J-

41413-OBD)] and pressure pump to EVAP service port.

2. Turn ignition switch ON.

3. Select the “EVAP SYSTEM CLOSE” in “WORK SUPPORT” mode of “ENGINE” using CONSULT.

4. Touch “START”. A bar graph (Pressure indicating display) will appear on the screen.

5. Apply positive pressure to the EVAP system until the pressure indicator reaches the middle of the bar

graph.

6. Remove EVAP service port adapter [commercial service tool: (J-41413-OBD)] and hose with pressure

pump.

7. Locate the leak using a leak detector [commercial service tool:

(J-41416)]. Refer to 

EC-49, "EVAPORATIVE EMISSION SYS-

TEM : System Description"

.

Without CONSULT

1. Install EVAP service port adapter [commercial service tool: (J-

2. Apply battery voltage between the terminals of EVAP canister vent control valve to make a closed EVAP

system.

3. To locate the leak, deliver positive pressure to the EVAP system until pressure gauge points reach 1.38 to

2.76 kPa (0.014 to 0.028 kg/cm

2

, 0.2 to 0.4 psi).

4. Remove EVAP service port adapter [commercial service tool: (J-41413-OBD)] and hose with pressure

pump.

5. Locate the leak using a leak detector [commercial service tool:

(J-41416)]. Refer to
