Inspection

1.
Disconnect the negative (-) battery terminal.
2.
Pull out the relay from the engine compartment relay box.
Power Relay (Type A)
Check for continuity between the terminals.
A : Power outlet relay
B : Start relay
C : Front deicer relay
D : Blower relay
E : ACC relay
F : IG1 relay
G : IG2 relay
H : Rear defogger relay
I : Horn relay
J : Vaccum pump relay
1.
There should be continuity between the No.30 and No.87 terminals when power and ground are connected to the No.85 and No.86 terminals.
2.
There should be no continuity between the No.30 and No.87 terminals when power is disconnected.

Power Relay (Type B)
Check for continuity between the terminals.
A : Wiper relay (Low)
B : Wiper relay (High)
1.
There should be continuity between the No.30 and No.87 terminals when power and ground are connected to the No.85 and No.86 terminals.
2.
There should be continuity between the No.30 and No.87 terminals when power is disconnected.

Power Relay (Type C)
Check for continuity between the terminals.
A : Cooling fan relay
1.
There should be continuity between the No.30 and No.87 terminals when power and ground are connected to the No.85 and No.86 terminals.
2.

Fuse
1.
Be sure there is no play in the fuse holders, and that the fuses are held securely.
2.
Are the fuse capacities for each circuit correct?
3.
Are there any blown fuses?
If a fuse is to be replaced, be sure to use a new fuse of the same capacity. Always determine why the fuse blew first and completely eliminate the problem before installing a new fuse.
Multi Fuse

-
Multi fuse has to replace in the mass when it damaged only one fuse.
