Interrupt Relay: Inspection

WARNING: This page is about a different car, the 2005 Subaru Baja. However, it is still accessible from the selected car via links, so may be relevant.

Measure the interrupt relay resistance between terminals (indicated in the table below) when connecting terminal No. 1 to battery positive terminal and terminal No. 4 to battery ground terminal.

INTERRUPT RELAY TERMINALS RESISTANCE

Current	Terminal No.	Standard
Flow	2 - 6	More than 1 MΩ
No flow	2 - 6	Less than 1 Ω
