Repair procedures
Inspection
1.
Disconnect the negative (-) battery terminal.
2.
Pull out the relay from the engine compartment relay block.
Power Relay (Type A)
Check for continuity between the terminals.
1.
After supplying power to between No. 85 and 86 power relay terminals, check that there is continuity between No. 30 and 87 terminals.
2.
After disconnecting power between No. 85 and 86 power relay terminals, check that there is no continuity between No. 30 and 87 terminals.
Engine Room Relay Block
Power Relay (Type B)
Check for continuity between the terminals.
1.
After supplying power to between No. 85 and 86 power relay terminals, check that there is continuity between No. 30 and 87 terminals.
2.
After disconnecting power between No. 85 and 86 power relay terminals, check that there is no continuity between No. 30 and 87 terminals.
Metal Core PCB block
1.
Disconnect the negative (-) battery terminal.
2.
Remove the multi fuse.
3.
Push the four hooks (B) in the direction of the arrow and lift up the metal core PCB block (A).

4.
Remove the metal care PCB block by disconnet the connector.

Fuse
1.
Check that the fuse holders are loosely held and that the fuses are securely fixed by the holders.
2.
Check that each fuse circuit has the exact fuse capacity.
3.
Check the fuses for any damage.
  
•
If a fuse is to be replaced, be sure to use a new fuse of the same capacity. Always identify the cause of the blown fuse and completely eliminate the problem before installing a new fuse.
Multi Fuse
Engine room fuse is to optimize the package.

  
•
The entire multi fuse (A) has to be replaced even if only one fuse is damaged.
•
When replacing it, refer to "the Engine compartment- component location" diagram to check fuse capacities and circuit arrangement.
•
Use the multi fuse of the exact fuse capacity for each circuit.
