Fuel pump control Circuit Inspection

■ Open check 

1. IG "OFF". Disconnect fuel control module, fuel pump connector.
2. Measure each harnesses' resistance of fuel pump control circuit (+), (-) between fuel control module and fuel pump harness connector.

   Specification:  below 1 Ω

3. Is the measured resistance within specification?

   YES 

   • Go to next procedure.

   NO 

   • Repair open in harness. Go to "VERIFICATION OF VEHICLE REPAIR " procedure.

■ Short to power check 

1. IG "OFF". Disconnect fuel control module, fuel pump connector.
2. Measure the resistance between + terminal and - terminal of fuel pump harness connector.

   Specification:  infinite

3. Is the measured resistance within specification?

   YES 

   • Go to "SYSTEM INSPECTION " procedure.

   NO 

   • Repair short in harness. Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
