Checking and replacing fuses
Turn the power switch off.
After a system failure, see “Fuse layout and amperage ratings”
for details about which fuse to check. (P. 787)
Open the fuse box cover.
Engine compartment:
Remove the engine compart-
ment cover (P. 740) and
remove all of the clips.
Push the tabs on either side to
detach the lock and lift the lid
off while pulling the lock
plate.
When installing the lid, check
that the lock plate and the tabs
on either side are connected cor-
rectly.
If any of the electrical components do not operate, a fuse may have
blown. If this happens, check and replace the fuses as necessary.
