BLOWN FUSE F1 20A
CARRY OUT 3D CHECKS
If the fuse F1 20A is blown, there is a short or a ground in electrical parts
or wire harness. Check them and replace the defective parts or repair the
wire harness.

BLOWN FUSE F2 F8A
CARRY OUT 3D CHECKS
1. If the fuse F2 F8A is blown when the door is opened, check the
monitored latch switch SW1 and monitor switch SW3.
2. If the fuse F2 F8A is blown by incorrect door switching replace the
defective switch(es) and the fuse F2 F8A.
