This a perfectly written research and instruction guide. This enhancement is a must-have
The module is PTG (not PTS).
I recoded both #1 + #4

+++++
One problem.... now when I use keyfob to open my trunk, it recloses automatically up+down right away.
This has to do with #1 option.
Its like the keyfob trunk-buton is now a "close trunk".
I am going to back track on #1 "inactive" until further testing.

I want to limit additional variables to suspect screwing things up.
Tweaking programmable firmware is awesome but proceed with caution. Go ahead do more poking and testing, there's more room for improvements.

I am in trouble with a turn signal coding(flickers twice) and could not backup. (OLC_turn Signal_model)
I tried to restored the setting back but did not work.
Is there a way to solve the problem?




I will send you the exact screen with my modification once I return to my house in the evening. (Currently living in South Korea)
This really gives me headache, and hope it will get recovered.
I have another question.
I did perform backup before writing codes, not the above one but other codes, few days ago.
Is there a way to recover the previous state to where I performed last backup before coding?
I dont know what it means 'backup' before writing code. (Whether it is just for that particular menu or whole coding itself)
Thank you so much.

What backup you don't have, you can not restore
