Check A/C relay component resistance
IG KEY "OFF", ENGINE "OFF".
Disconnect A/C relay.
Measure the resistance of A/C relay coil.
Specification :80±5 Ω (20℃)
Is the measured resistance within the specification?
YES
Go to "2. Check A/C relay component operation" as follows.
NO
Replace A/C relay and go to "Verification of Vehicle Repair".
Check A/C relay component operation
IG KEY "OFF", ENGINE "OFF".
Disconnect A/C relay.
Supplies random B+ and ground to coil sides of A/C relay ( terminal 85, terminal 86).
Check continuity between A/C 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 continuity test within the specification?
YES
Go to "Verification of Vehicle Repair".
NO
Replace A/C relay and go to "Verification of Vehicle Repair".
