Check fuel pump relay component coil resistance
IG KEY "OFF", ENGINE "OFF".
Disconnect fuel pump relay.
Measure the resistance of fuel pump relay component coil.
Specification : 75±5 Ω (20℃)
Is the measured resistance within the specification?
YES
Go to "2. Check fuel pump relay component operation" as follows.
NO
Replace fuel pump relay and go to "Verification of Vehicle Repair".
Check fuel pump relay component operation
IG KEY "OFF", ENGINE "OFF"
Disconnect fuel pump relay.
Supplies random B+ and ground to coil sides of fuel pump relay ( terminal 85, terminal 86).
Check continuity between fuel pump relay terminal 30 and terminal 87.
Specification : When power is supplied : Continuity ( below 1.0Ω )
When power is not supplied : Discontinuity ( Infinite Ω )
Is the measured resistance within the specification?
YES
Go to "Verification of Vehicle Repair".
NO
Replace fuel pump relay and go to "Verification of Vehicle Repair".
Repeat this process 2~3 times.
