FUEL PRESSURE RELEASE

NOTE:

If following procedure performed, a certain DTC may be detected.

With CONSULT-III

1. Lift up the vehicle.
2. Turn ignition switch ON (READY).
3. Depress the accelerator pedal and keep it.
4. Shift the selector lever to N position with engine running.

CAUTION:

Never leave the selector lever in the N position for a long period of time. In the N position, the

engine operates but electricity cannot be generated.

5. Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT” mode with CONSULT-III.
6. After engine stalls, turn ignition switch OFF.

Without CONSULT-III

1. Turn ignition switch OFF.
2. Remove fuel pump fuse located in IPDM E/R.
3. Turn ignition switch ON (READY).
4. Depress the accelerator pedal and keep it.
5. After engine stalls, turn ignition switch OFF.
6. Reinstall fuel pump fuse after servicing fuel system.

FUEL PRESSURE CHECK

CAUTION:

Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.

NOTE:

• Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel

pressure cannot be completely released because HL32 models do not have fuel return system.

• Use Fuel Pressure Gauge Kit [SST: (J-44321)] to check fuel pressure.
1. Release fuel pressure to zero.
2. Disconnect the fuel quick connector on the engine side.
3. Install fuel pressure gauge adapter (B) with fuel pressure gauge

(A).

4. Turn ignition switch ON and check for fuel leakage.
5. Check DTC.

If DTC is detected, erase DTC and go to next steps.

If DTC is not detected, go to next steps.

6. Activate “INSPECTION MODE 1” (

HBC-104

) to start engine,

and check for fuel leakage.

7. Read the indication of fuel pressure gauge.

8. If result is unsatisfactory, check fuel hoses and fuel tubes for clogging.

If OK, Replace “fuel filter and fuel pump assembly”.

If NG, Repair or replace.

At idling : Approximately 350 kPa (3.57 kg/cm

, 51 psi)

EVAP LEAK CHECK

EVAP LEAK CHECK

Inspection

INFOID:0000000004211675

CAUTION:

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

, 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.

WITH CONSULT-III

1. To locate the EVAP leak, install EVAP service port adapter [com-

mercial service tool: (J-41413-OBD)] and pressure pump to

EVAP service port.

2. Turn ignition switch ON.
3. Select the “EVAP SYSTEM CLOSE” of “WORK SUPPORT”

mode with CONSULT-III.

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-63, "System Diagram"

WITHOUT CONSULT-III

1. To locate the EVAP leak, install EVAP service port adapter [com-

mercial service tool: (J-41413-OBD)] and pressure pump to

EVAP service port.

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

, 0.2 to 0.4 psi).

4. Remove EVAP service port adapter [commercial service tool: (J-

41413-OBD)] and hose with pressure pump.
