There should be no continuity between the No. 1 and No. 2 terminals when power is disconnected.


type 1:


type 2:

· PGM-FI main relay 1
· PGM-FI main relay 2

type 1:


type 2:


Normally-open type B:

Check for continuity between the terminals.

There should be continuity between the No. 1 and No. 3 terminals when power and ground are connected to the No. 2 and No. 4 terminals.

There should be no continuity between the No. 1 and No. 3 terminals when power is disconnected.




Five terminal type

Check for continuity between the terminals.

There should be continuity between the No. 1 and No. 2 terminals when power and ground are connected to the No. 3 and No. 5 terminals.

There should be continuity between the No. 1 and No. 4 terminals when power is disconnected.
