Standard Resistance:

Tester Connection	Condition	Specified Condition
3 - 5	Battery voltage not applied between terminals 1 and 2	10 kΩ or higher
3 - 5	Battery voltage applied between terminals 1 and 2	Below 1 Ω
3 - 4	Battery voltage not applied between terminals 1 and 2	Below 1 Ω
3 - 4	Battery voltage applied between terminals 1 and 2	10 kΩ or higher

If the result is not as specified, replace the No. 1 mirror relay.
