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.

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.
