Unable to add sound to Automation car

The text may be strange because it uses machine translation.

I tried to add blinker sounds, reverse Warn sounds, etc. to the Automation car.
There is no blinker sound, and the reverse Warn sound cannot be adapted to a custom sound and does not sound.
I did a lot of trial and error, but it still didn't make any sound.

Please tell me who knows the cause.
I will post the text.

I may be mistaken, but I'm not sure if you can give Automation vehicles any of the stock BeamNG sounds (or other things).

Also, you have a double comma after the square bracket in two places; there should only be one

 

I didn't know that fact.
Thank you for teaching me

I've just started making mods recently, so it's certainly hard to understand the code.
I think I'll rewrite the code again.
