Work Procedure
INFOID:0000000009178086
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 2 or 3 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 2 or 3 times to release all fuel pres-
sure.
4. Turn ignition switch OFF.
5. 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 this models do not have fuel return system.
• Be careful not to scratch or get the fuel hose connection area dirty when servicing, so that the quick
connector o-ring maintains seal ability.
• Use Fuel Pressure Gauge Kit [SST: — (J-44321)] and Fuel Pressure Adapter [SST: — (J-44321-6)] to
check fuel pressure.
1. Release fuel pressure to zero.
2. Remove fuel hose using Quick Connector Release [SST: — (J-45488)].
• 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.
• Do not distort or bend fuel rail tube when installing fuel pres-
sure gauge adapter.
• When reconnecting fuel hose, check the original fuel hose 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)].
• During fuel pressure check, check for fuel leakage from fuel connection every 3 minutes.

7. If result is unsatisfactory, go to next step.
8. Check the following.
• Fuel hoses and fuel tubes for clogging
• Fuel filter for clogging
• Fuel pump
• Fuel pressure regulator for clogging
9. If OK, replace fuel pressure regulator.
If NG, repair or replace malfunctioning part.
10. Before disconnecting Fuel Pressure Gauge kit [SST: — (J-44321)] and Fuel Pressure Adapter [SST: — (J-
44321-6)], release fuel pressure to zero.

HOW TO SET SRT CODE
Description
INFOID:0000000009178087
OUTLINE
In order to set all SRTs, the self-diagnoses as in the “SRT ITEM” table must have been performed at least
once. Each diagnosis may require actual driving for a long period of time under various conditions.
SRT ITEM
The table below shows required self-diagnostic items to set the SRT to “CMPLT”.
*1: Though displayed on the CONSULT screen, “HO2S HTR” is not SRT item.
*2: If completion of several SRTs is required, perform driving patterns (DTC confirmation procedure), one by
one based on the priority for models with CONSULT.
