Inspection

Power Relay Test (Type A)
Check for continuity between the terminals.
1. There should be continuity between the No.1 and No.2 terminals when power and ground are connected to the No.3 and No.4 terminals.
2. There should be no continuity between the No.1 and No.2 terminals when power is disconnected.
A : A/T relay
B : Fuel pump relay
C : Air conditioning relay
D : Front fog relay
E : Horn relay









Power Relay Test (Type B)
Check for continuity between the terminals.
1. 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.
2. There should be continuity between the No.1 and No.4 terminals when power is disconnected.
A : Wiper relay









Power Relay Test (Type C)
Check for continuity between the terminals.
1. There should be continuity between the No.1 and No.4 terminals when power and ground are connected to the No.2 and No.3 terminals.
2. There should be no continuity between the No.1 and No.4 terminals when power is disconnected.
A : Head lamp relay(Low)
B : Head lamp relay(High)
C : Start relay









Power Relay Test (Type D)
Check for continuity between the terminals.
1. There should be continuity between the No.1 and No.4 terminals when power and ground are connected to the No.2 and No.3 terminals.
2. There should be continuity between the No.1 and No.5 terminals when power is disconnected.
A : E/G control (Main relay)










Fuse Inspection
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.
