Never touch terminals of ECM itself or connect voltmeter or ohmmeter (2).

2) Connect special tool to ECM connectors securely.
NOTE
Do not connect the other connector of special tool to ECM.

3) Check resistance between each pair of terminals of disconnected connectors (1) as listed in the following table.
CAUTION!
• Be sure to connect ohmmeter probe from wire harness side of coupler.
• Be sure to turn OFF ignition switch for this check.

Fuel Pressure Relief ProcedureS7RS0B1706003
CAUTION!
This work must not be done when engine is
hot. If done so, it may cause adverse effect to
catalyst.

NOTE
If ECM detects DTC(s) after servicing, clear
DTC(s) referring to “DTC Clearance in
Section 1A”.

1) Make sure that engine is cold.
2) Shift transaxle gear shift lever in “Neutral” (shift select lever in “P” range for A/T model), set parking
brake and block drive wheels.
3) Remove relay / fuse box cover.
4) Disconnect fuel pump relay (1) from relay / fuse box (2).
5) Remove fuel filter cap in order to release fuel vapor pressure in fuel tank, and then reinstall it.
6) Start engine and run it until engine stops for lack of fuel. Repeat cranking engine 2 – 3 times for about 3
seconds each time in order to dissipate fuel pressure
in lines. Fuel connections are now safe for servicing.
7) After servicing, connect fuel pump relay (1) to relay / fuse box and install re lay / fuse box cover.
Fuel Leakage Check ProcedureS7RS0B1706004
After performing any service on fuel system, check to
make sure that there are no fuel leakages as follows.
1) Turn ON ignition switch for 3 seconds (to operate fuel pump) and then turn it OFF.
Repeat this (ON and OFF) 3 or 4 times and apply
fuel pressure to fuel line until fuel pressure is felt by
hand placed on fuel feed hose.
2) In this state, check to see that there are no fuel leakages from any part of fuel system.
Fuel Lines On-Vehicle InspectionS7RS0B1706005
CAUTION!
Due to the fact that fuel feed line (1) is under
high pressure, use special care when
servicing it.

Visually inspect fuel lines for evidence of fuel leakage,
hose crack and deterioration or damage.
Make sure all cl amps are secure.
Replace parts as needed.
Fuel Pipe Removal and InstallationS7RS0B1706006
WARNING!
Before starting the following procedure, be
sure to observe “Precautions on Fuel System
Service” in order to reduce the risk or fire
and personal injury.

Removal
1) Relieve fuel pressure in fuel feed line according to “Fuel Pressure Relief Procedure”.
2) Disconnect negative cable at battery.
3) Disconnect fuel pipe joint and fuel hose (3) from fuel pipe (2) at the front and rear of each fuel pipe
referring to “Fuel Hose Disconnecting and
Reconnecting”.
4) Mark the location of clamps (1) on fuel pipes (2), so that the clamps can be reinstalled to where they
were.
5) Remove pipes (2) with clamp (1) from vehicle.
6) Remove clamp (1) from pipes (2).

Generator Test (Undercharged Battery Check)S7RS0B1A04003
This condition, as evidenced by slow cranking or
indicator clear with dark or light yellow dot can be
caused by one or more of the following conditions even
though indicator lamp may be operating normal.
The following procedure also applies to cars with
voltmeter and ammeter.1) Make sure that undercharged condition has not been caused by accessories left on for extended period of
time.
2) Check drive belt for proper tension.
3) If battery defect is suspected, refer to “Battery Description”.
4) Inspect wiring for defects. Check all connections for tightness and cleanliness, battery cable connections
at battery, starting motor, ignition ground cable and
no “C” terminal circuit at ground.
5) Connect switch (6), load (5), battery (4), voltmeter (3) and ammeter (2) to generator (1) as shown in
figure.
Voltmeter: Set between generator “B” terminal
and ground.
Ammeter: Set between generator “B” terminal
and battery (+) terminal.
NOTE
Use fully charged battery.

6) Measure current and voltage.
No-Load Check 1) Run engine from idling up to 2000 rpm and read meters.
NOTE
Turn off switches of all accessories (wiper,
heater etc.).

Specification for undercharged battery (No-load
check)
Current: 10 A
Voltage: 14.2 – 14.8 V (at 20 °C, 68 °F)
NOTE
Consideration should be taken that voltage
will differ somewhat with regulator case
temperature as shown in figure.

2) Using service wire, ground “C” terminal (1) of
generator.
3) Measure voltage between “B” terminal of generator and body ground.
Voltage: 12.5 – 13.1 V (at 20 °C, 68 °F)
• If voltage is higher than standard value
If voltage is higher than standard value, check ground
of brushes.
If brushes are not grounded, replace IC regulator.
If voltage is lower than standard value, proceed to the
following check.
Load Check 1) Run engine at 2000 rpm and turn on head light and blower motor.
2) Measure current. If measure current is less than 30 A, repair or
replace generator.
