Disconnect the negative (-) battery terminal.
Pull out the relay from the engine compartment relay box.
Check for continuity between the terminals.
A : Fuel pump relay
B : A/C relay
C : Horn relay
D : Windshied deicer relay
E : Fuel filter heater relay
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.
There should be no continuity between the No.30 and No.87 terminals when power is disconnected.
Check for continuity between the terminals.
A : Wiper relay (Low)
B : Wiper relay (High)
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.
There should be continuity between the No.30 and No.87 terminals when power is disconnected.
Check for continuity between the terminals.
A : Condenser pan relay #1
B : Start #1 relay
C : Condenser pan relay #2
D : Blower relay
E : Rear glass defogger relay
F : PTC heater relay #2
G : PTC heater relay #1
H : PTC heater relay #3
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.
There should be no continuity between the No.30 and No.87 terminals when power is disconnected.
Check for continuity between the terminals.
A : Main relay
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.
There should be continuity between the No.30 and No.87 terminals when power is disconnected.
Be sure there is no play in the fuse holders, and that the fuses are held securely.
Are the fuse capacities for each circuit correct?
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 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.
