Diagnosis steps

1. Check fuse

(a). Ignition switch:"ON"..

(b). Check the fuse F10(10A) in the engine
compartment fuse box and the fuse
F19(5A) in the internal fuse box for
burnout.

Check if the result is normal?
YES ＞ Replace the fuse.
Note :
The new fuse to replace must have and equivalent rated amperage. F10 fuse has an
amperage of 10A and F19 has an amperage of 5A.
NO> To step 2.
