6. CHECK 15A FUSE
1. Turn ignition switch OFF.
2. Disconnect 15A fuse.
3. Check 15A fuse.
OK or NG
OK >> GO TO 7.
NG >> Replace fuse.
7. CHECK FUEL PUMP POWER SUPPLY CIRCUIT-IV
1. Disconnect IPDM E/R harness connector E8.
2. Check harness continuity between IPDM E/R terminal 39 and “fuel level sensor unit and fuel pump” termi- nal 1.
Refer to Wiring Diagram.
3. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 11.
NG >> GO TO 8.
8. DETECT MALFUNCTIONING PART
Check the following.

Harness connectors E206, B6

Harness for open or short between IPDM E/R and “fuel level sensor unit and fuel pump”
>> Repair open circuit or short to ground or short to power in harness or connectors.
9. CHECK FUEL PUMP GROUND CIRCUIT FOR OPEN AND SHORT
1. Check harness continuity between “fuel level sensor unit and fuel pump” terminal 3 and ground. Refer to Wiring Diagram.
2. Also check harness for short to power.
OK or NG
OK >> GO TO 10.
NG >> Repair open circuit or short to power in harness or connectors.
10. CHECK FUEL PUMP
Refer to EC-1323, "
Component Inspection" .
OK or NG
OK >> GO TO 11.
NG >> Replace “fuel level sensor unit and fuel pump”.
11 . CHECK INTERMITTENT INCIDENT
Refer to EC-812, "
TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" .
OK or NG
OK >> Replace IPDM E/R. Refer to PG-17, "IPDM E/R (INTELLIGENT POWER DISTRIBUTION MOD-
ULE ENGINE ROOM)"
NG >> Repair or replace harness or connectors. Continuity should exist.
Continuity should exist.

IGNITION COIL WITH POWER TRANSISTOR
CAUTION:
Do the following procedure in the place where ventilation is good without the combustible.
1. Turn ignition switch OFF.
2. Disconnect ignition coil harness connector.
3. Check resistance between ignition coil terminals as follows.
4. If NG, Replace ignition coil with power transistor. If OK, go to next step.
5. Turn ignition switch OFF.
6. Reconnect all harness connectors disconnected.
7. Remove fuel pump fuse in IPDM E/R to release fuel pressure.
NOTE:
Do not use CONSULT-II to release fuel pressure, or fuel pres-
sure applies again during the following procedure.
8. Start engine.
9. After engine stalls, crank it two or three times to release all fuel pressure.
10. Turn ignition switch OFF.
11. Remove ignition coil harness connectors to avoid the electrical discharge from the ignition coils.
12. Remove ignition coil and spark plug of the cylinder to be checked.
13. Crank engine for 5 seconds or more to remove combustion gas in the cylinder.
14. Connect spark plug and harness connector to ignition coil.
15. Fix ignition coil using a rope etc. with gap of 13 - 17 mm between the edge of the spark plug and grounded metal portion
as shown in the figure.
16. Crank engine for about 3 seconds, and check whether spark is generated between the spark plug and the grounded part.
CAUTION:

Do not approach to the spark plug and the ignition coil
within 50cm. Be careful not to get an electrical shock
while checking, because the electrical discharge voltage
becomes 20kV or more.

It might cause to damage the ignition coil if the gap of more than 17 mm is taken.
NOTE:
When the gap is less than 13 mm or less, the spark might be generated even if the coil is malfunc-
tioning.
17. If NG, Replace ignition coil with power transistor.
Terminal No. (Polarity) Resistance Ω [at 25 °C (77 °F)]
1 and 2 Except 0 or ∞
1 and 3 Except 0
2 and 3
Spark should be generated.
