What options to activate to have ground impulse on AUX1

Question

Kia Sedona with OEM remote start.

What options should be activated to have 1 short ground impulse on AUX1.

Answer 1

option 25 controls the AUX1 yellow/black wire of the evo-one.

25.1 for a short pulse

Comments

Was not able to make it work. Can not get negative pulse on yellow/black wire.  Was thinking over it, and came to the following conclusion as to the logiс of this , please confirm or correct me if i'm wrong.

If you put option 25 to 25.1 and temperature option 39 to disable (39.1) - then negative pulse will never appear on yellow/black wire until you press AUX1 button on the remote (and it should not be the OEM remote). This means if your system only has OEM remotes, you will not be able to activate this functionality.

The only way it will work having just OEM remotes is to activate temperature control to 39.2 and then it should automatically have negative pulse if the temperature is below +5.  (since it is +13 now, can not check my theory).

The bottom line - is is possible to make AUX1 produce pulse negative without 3rd party RF remotes every time regardless of the temperature reading?  If yes, please advise all the bypass and remote starter options (options - 35, 34, 25, a4, a5, a6)

Correct

Correct. Also keep in mind that if +4C outside, in the inside of the car, it may be +6. The thermostat is built into the evo.

Unfortunately no. With factory remotes you will be limited since there is no controllable AUX command. Enabling 39.2 is the only option.

Thank you so much Robb.  It is too bad there is nothing about in in tech docs. 

The last question is how options like 35, 34, a4, a5, a6 influence the logis of AUX1 when it is set to be temperature triggered by 39.2?

and what type of diodes would you recommend if I need to separate the heated seats and rear defrost to be both triggered by AUX1.

A4-5-6 controls Heated XYZ on vehicles that we can control them through CAN.  It will say in the guide, first page, when it's controlled on CAN. We also use A5-6 for random things to.

34 and 35 have nothing to do with AUX or 39.2. 

• 34 control truck output on the analog wire AND when trunk is controlled through CAN. 
• 35 is to pulse ignition on unlock. Used only on some Fords. 

 

39 only affects AUX1. So option 25 for analog wire, and option A5 when available (it will be in the guide).
