WARNING:
When replacing fuel line parts, be sure to observe the following:
IDisplay a ªCAUTION: INFLAMMABLEº sign in workshop.
I Be sure to furnish workshop with a CO
2fire extinguisher service.
I Do not smoke while servicing fuel system. Keep open flames and sparks away from work area.
I Be sure to disconnect battery ground cable before conducting operations.
I Pour drained fuel into an explosion-proof container, then ensure container lid is installed securely.
CAUTION:
I For ECM models, release fuel pressure from fuel line. Refer to EC section (ªFuel Pressure Releaseº,
ªBASIC SERVICE PROCEDUREº).
I Do not disconnect any fuel line unless absolutely necessary.
I Plug hose and pipe openings to prevent entry of dust or dirt.
I Always replace top lid seal and hose clamps with new ones.
I Do not kink or twist hoses and tubes during installation.
I Do not tighten hose clamps excessively because this could cause damage to the hose.
I Ensure fuel check valve is installed in the correct orientation.
I Refer to EC section (ªFUEL CHECK VALVEº, ªEVAPORATIVE EMISSION SYSTEMº).
I After installation, run engine and check for fuel leaks at connections.
Fuel Pump and Gauge
REMOVAL
Petrol engine
1. Release fuel pressure from fuel line.
Refer to EC section (ªFuel Pressure Releaseº, ªBASIC SER-
VICE PROCEDUREº).
2. Remove inspection hole cover located under the luggage com- partment carpet.
3. Remove fuel filler lid.
4. Disconnect fuel outlet, return tube and connectors.
CAUTION:
Mark the fuel tubes to ensure correct position during installa-
tion.
5. Remove the fuel gauge assembly and disconnect tubes and connector.

Self-diagnosis
After performing this procedure, place check marks for results on
the ªDIAGNOSTIC WORKSHEETº, AT-24. Reference pages are
provided following the items.
SELF-DIAGNOSTIC PROCEDURE (With CONSULT-II)
1. Turn on CONSULT-II and touch ªA/Tº.If A/T is not displayed, check TCM power supply and ground
circuit. Refer to AT-46. If result is NG, refer to EL section
(ªPOWER SUPPLY ROUTINGº).
2. Touch ªSELF-DIAG RESULTSº. Display shows malfunction experienced since the last erasing
operation.
CONSULT-II performs REAL-TIME SELF-DIAGNOSIS.
Also, any malfunction detected while in this mode will be dis-
played at real time.

Diagnosis by CONSULT-II
NOTICE
1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of eachsolenoid).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Manual may differ slightly. This occurs because of the following reasons:
IActual shift schedule has more or less tolerance or allowance,
I Shift schedule indicated in Service Manual refers to the point where shifts start. Gear position displayed
on CONSULT-II indicates the point where shifts are completed.
3. Shift solenoid valve ªAº or ªBº is displayed on CONSULT-II at the start of shifting. Gear position is displayed upon completion of shifting (which is computed by TCM).
4. Additional CONSULT-II information can be found in the Operation Manual supplied with the CONSULT-II unit.
