Check main relay component resistance

(1)

IG KEY "OFF", ENGINE "OFF".

(2)

Disconnect main relay.

(3)

Measure the resistance between main relay control terminals (Component side).

Specification : 73±10 Ω (20°C)

(4)

Is the measured resistance within the specification?

	▶ Go to "2. Check main relay component operation" as follows.
	▶ Replace main relay and go to "Verification of Vehicle Repair".

Check main relay component operation

(1)

IG KEY "OFF", ENGINE "OFF".

(2)

Disconnect main relay.

(3)

Supplies random B+ and ground to coil sides of main relay. (Component side)

(4)

Check continuity between main relay power supply terminals - 30 and 87. (Component side)

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

When power is not supplied : Discontinuity ( Infinite Ω )

(5)

Is the continuity test within the specification?

	▶ Go to "Verification of Vehicle Repair".
	▶ Replace main relay and go to "Verification of Vehicle Repair".

※ Repeat this process 2~3 times.
