NO >> GO TO 3.
3.DETECT MALFUNCTIONING PART
Check the following.
• Harness or connectors E8, F1 • IPDM E/R connector E13 • Harness for open or short to ground and short power
>> Repair open circuit or short to ground or short to power in harness or connectors.
4.CHECK FUEL PUMP POWER SUPPLY CIRCUIT-III
1. Turn ignition switch OFF.
2. Reconnect all harness connectors disconnected.
3. Disconnect “fuel level sensor unit and fuel pump” harness connector.
4. Turn ignition switch ON.
5. Check voltage between “fuel level sensor unit and fuel pump” harness connector and ground.
Is the inspection result normal? YES >> GO TO 8.
NO >> GO TO 5.
5.CHECK 15 A FUSE
1. Turn ignition switch OFF.
2. Disconnect 15 A fuse (No. 60) from IPDM E/R.
3. Check 15 A fuse.
Is the inspection result normal? YES >> GO TO 6.
NO >> Replace fuse.
6.CHECK FUEL PUMP POWER SUPPLY CIRCUIT-IV
1. Disconnect IPDM E/R harness connector.
2. Check the continuity between IPDM E/R harness connector and “fuel level sensor unit and fuel pump” harness connector.
3. Also check harness for short to ground and short to power.
Is the inspection result normal? YES >> GO TO 10.
NO >> GO TO 7.
7.DETECT MALFUNCTIONING PART
Check the following.
• Harness connectors E105, M77 • Harness connectors B1, M18 • 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.
8.CHECK FUEL PUMP GROUND CIRCUIT
1. Check the continuity between “fuel level sensor unit and fuel pump” and ground.
2. Also check harness for short to power.
Is the inspection result normal? YES >> GO TO 9.
NO >> Repair open circuit or short to power in harness or connectors.
9.CHECK FUEL PUMP
Refer to EC-782, "Component Inspection".
Is the inspection result normal? YES >> GO TO 10.
NO >> Replace “fuel level sensor unit and fuel pump”.
10.CHECK INTERMITTENT INCIDENT
Refer to GI-42, "Intermittent Incident".
Is the inspection result normal? YES >> Replace IPDM E/R.
NO >> Repair or replace harness or connectors.
Component Inspection
1.CHECK FUEL PUMP
