VIN REGISTRATION
DescriptionINFOID:0000000009462561
VIN Registration is an operation to register VIN in
ECM. It must be performed each time ECM is replaced.
NOTE:
Accurate VIN which is registered in ECM ma y be required for Inspection & Maintenance (I/M).
Work ProcedureINFOID:0000000009462562
1.CHECK VIN
Check the VIN of the vehicle and note it. Refer to GI-24, "Identification Plate"
.
>> GO TO 2.
2.PERFORM VIN REGISTRATION
With CONSULT
1. Turn ignition switch ON with engine stopped.

FUEL PRESSURE RELEASE
1.FUEL PRESSURE RELEASE
With CONSULT
1. Turn ignition switch ON.
2. Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT” mode with CONSULT.
3. Start engine.
4. After engine stalls, crank it two or three times to release all fuel pressure.
5. Turn ignition switch OFF.
Without CONSULT
1. Remove fuel pump fuse located in IPDM E/R.
2. Start engine.
3. After engine stalls, crank it two or three times to release all fuel pressure.
4. Turn ignition switch OFF.
5. Reinstall fuel pump fuse after servicing fuel system.

FUEL PRESSURE CHECK
CAUTION:
• The fuel hose connection method used when taki ng fuel pressure check must not be used for other
purposes.
• Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
• Be careful not to scratch or get the fuel hose conn ection area dirty when servicing, so that the quick
connector o-ring ma intains seal ability.
• Use Fuel Pressure Gauge Kit [SST: — (J-44321)] an d Fuel Pressure Adapter [SST: — (J-44321-6)] to
check fuel pressure.
NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pres-
sure cannot be completely released because th is models do not have fuel return system.
1.FUEL PRESSURE CHECK
1. Release fuel pressure to zero.
2. Remove fuel hose using Quick Connector Release [SST: — (J-45488)]. CAUTION:
• Do not twist or kink fuel hose because it is plastic hose.
• Do not remove fuel hose from quick connector.
• Keep fuel hose connections clean.
3. Install Fuel Pressure Adapter [SST: — (J-44321-6)] (B) and Fuel Pressure Gauge kit [SST: — (J44321)] (A) as shown in figure.
CAUTION:
• Do not distort or bend fuel rail tube when installing fuel
pressure gauge adapter.
• When reconnecting fuel hose, check the original fuel hose
(1) for damage and abnormality.
4. Turn ignition switch ON (reactivate fuel pump) and check for fuel leakage.
5. Start engine and check for fuel leakage.
6. Read the indication of fuel pressure gauge kit [SST: — (J- 44321)].
CAUTION:
• During fuel pressure check, check for fuel leakage from fuel connection every 3 minutes.
Is the inspection result normal?

6.PATTERN 2
1. Drive the vehicle. And depress the accelerator pedal until vehicle speed is 90 km/h (56 MPH), then
release the accelerator pedal and keep it released for more than 10 seconds.
2. Depress the accelerator pedal until vehicle speed is 90 km/h (56 MPH) again
NOTE:
• Checking the vehicle speed with GST is advised.
• When steady-state driving is performed again even afte r it is interrupted, each diagnosis can be conducted.
In this case, the time required for diagnosis may be extended.
>> GO TO 7.
7.PATTERN 3
• Operate vehicle following the driving pattern shown in the figure.
• Release the accelerator pedal during deceleration of vehicle speed
from 90 km/h (56 MPH) to 0 km/h (0 MPH).
>> GO TO 8.
8.PATTERN 4
• Operate vehicle, following the driving pattern shown in the figure.
- Drive the vehicle in a proper gear at 60 km/h (38 MPH) and main-
tain the speed.
- Release the accelerator pedal fully at least 5 seconds.
- Repeat the above two steps at least 5 times.
>> GO TO 9.
9.PATTERN 5
• The accelerator pedal must be held very steady during steady-state driving.
• If the accelerator pedal is moved, the test must be conducted again.
>> GO TO 10.
10.PATTERN 6
• Cool down the engine so that the engine c oolant temperature lowers between 15 – 35°C (59 – 95 °F).
CAUTION:
Never turn the ignition switch ON while cooling down the engine.
• Engine coolant temperature at engine start is between 15 – 35 °C (59 – 95 °F) and has lowered 45 °C (113 °F)
or more since the latest engine stop.
