Inspection

Power Relay Test (Type A)

- | Do not use pliers.

- | Pliers will damage the relays, which could cause the engine to stall or not start.

- | Carefully remove the relay using the relay puller.

Check for continuity between the terminals.

A. Front deicer B. Back up lamp relay C. IGN2 D. Start #1 relay (H1) E. HAC relay
F. IGN1
G. Start #2 relay
H. Cooling fan (HI) relay
I. Cooling fan (LO) relay
J. Blower relay
K. Rear defogger
L. Horn relay
M. ACC
N. Fuel 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 Test (Type C)
Check for continuity between the terminals.
A : Main relay

1. | There should be continuity between the No.30, 87a 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, 87a and No.87 terminals when power is disconnected.

Power Relay Test (Type B)
Check for continuity between the terminals.
A : Rain sensor relay
B : Wiper 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 continuity between the No.30 and No.87 terminals when power is disconnected.

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.

Multi Fuse
Multi Fuse is for optimizing the engine room package.

- | Multi fuse is needed to replace entirely when there is damage to only one fuse.

- | When replace the multi fuse, refer to the "Engine compartment - component location" diagram exactly.

- | Use the multi fuse capacities for each circuit correctly.
