Component Inspection
1.

Check A/C relay component resistance

(1)

IG KEY "OFF", ENGINE "OFF".

(2)

Disconnect A/C relay.

(3)

Measure the coil resistance of A/C relay.

1)

Secification : 85±5 Ω (20℃)

(4)

Is the measured resistance within the specification?

YES

a.

Go to "2. Check A/C relay component operation" as follows.

NO

a.

Replace A/C relay and go to "Verification of Vehicle Repair".

2.

Check A/C relay component operation

(1)

IG KEY "OFF", ENGINE "OFF".

(2)

Disconnect A/C relay.

(3)

Supplies random B+ and ground to coil sides of A/C relay ( terminal 85, terminal 86).

(4)

Check continuity between A/C relay terminal 30 and terminal 87.

1)

Secification : When power is supplied : Continuity ( below 1.0Ω )

When power is not supplied : Discontinuity ( Infinite Ω )

(5)

Is the continuity test within the specification?

YES

a.

Go to "Verification of Vehicle Repair".

NO

a.

Replace A/C relay and go to "Verification of Vehicle Repair".

※ Repeat this process 2~3 times.
