Circuit diagram:

Circuit diagram，refer to 11.8.6.1 electrical schematic diagram

Diagnostic steps:

1

Check the fuses IF13, IF25

A. Inspect whether the fuses IF13 and IF25 are broken.

Fuse Rating: respectively 20A, 10 A

2

Inspect the circuits of the fuses, IF13 and IF25.

A. Check whether fuse if13 and fuse if25 lines are short circuited.

B. Repair the circuits, Confirm that there are no short circuits.

C. Replace the fuses with rated current.

Confirm whether the sunroof is working properly.

3

Carry out the sunroof initial program.

A. Execute the sunroof initial program, refer to 11.2.7.3 sunroof Initializing.

Confirm whether the sunroof is working properly.

4

Inspect the sunroof switch harness connector RF13 and body ground.

Yes

The system is normal.

No

A. Remove the sunroof switch

assembly, reffer to 11.2.8.3
Replacement of Sunroof Switch
Assembly.

B. Measure the resistance between

terminal No.5 of the sunroof
switch harness connector RF13
and body ground with a
multimeter.

Standard resistant value :is less
than 1Ω

Confirm whether the resistance is at a
specified value.
