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 : Blower relay B : Horn relay C : Cooling fan relay (Low) D : Start relay E : Burglar horn relay F : Rear glass defogger relay G : ATM relay H : Windshied deicer relay I : Cooling fan relay (High) J : A/C relay K : 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 (Type B) Check for continuity between the terminals. A : Wiper relay (High) B : Wiper relay (Low)
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 : Main 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.
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 is needed to replace in the mass when it damaged 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.
