Check main relay component resistance
IG KEY "OFF", ENGINE "OFF".
Disconnect main relay.
Measure the resistance between main relay coil component terminal 85 and terminal 86.
Specification : 80±10 Ω (20℃)
Is the measured resistance within the specification?
YES
Go to "2. Check main relay component operation" as follows.
NO
Replace main relay and go to "Verification of Vehicle Repair".
Check main relay component operation
IG KEY "OFF", ENGINE "OFF"
Disconnect main relay.
Supplies random B+ and ground to coil sides of main relay. ( terminal 85, terminal 86)
Check continuity between main relay component terminal 30 and terminal 87, terminal 87a.
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 main relay and go to "Verification of Vehicle Repair".
※ Repeat this process 2~3 times.
