Purpose
Relays and fuses used by each system are grouped and housed together for smooth inspection and replacement servicing.
Function
Relays and fuses used by each system are grouped and housed together.
Construction
Installed in the engine compartment.

Operation
Relay operation
1. When electric current flows to the coil, electromagnetic power is generated.
2. The switch is attracted by the generated electromagnetic power and it switches on.
3. Electric current flows to each part that is downstream of the switch.

Fuse operation
1. If electric current to each fuse is the specified value or more, the fuse melts due to heat generation.
2. Interrupts electric current flow downstream of the fuse.
Fail-safe
Function not equipped.
