2015 Hyundai Genesis PTS Evo-One doesn't start

Question

I used guide 17323 revision 20140804 to wire up a 2015 Hyundai Genesis PTS to and EVO-One.  I have programmed the EVO-One and it responds as the directions say.  I have oem remote monitoring on, when I lock the doors three times, I get a blue blink every time I hit the lock button, on the third press the parking lights come on, the doors unlock, the car's dash screen comes on but it doesn't start.  The middle LED on  the EVO-One is lit orange and after about 5 seconds it locks and unlocks the doors, then about 5 seconds later it locks all the doors and the middle LED shuts off.  If I had to guess I would say that the starter out is either not sending the signal or the starter+ is not hooked up correctly?  I have it hooked to the brown orange wire in the loom indicated on the wiring diagram but there are a ton of wires there.  What else can I do to troubleshoot?  I am running firmware 76.16 with C1, D1, D1.6, D2 and D6 turned on

Answer 1

Verify your starter connection. If there is more than one brown/orange wire in the same harness you absolutly have to test the wire with a DMM BEFORE connecting anything to it.

The good start wire will show 12V for about a second when you start the car with the push button.

So, I finally got around to testing all of this and I found the issue (or what I think the issue is).  I got a power probe and hooked it to the brown/black wire (#16 on the 32 pin smart key module) per the diagrams I got off of Hyundai's tech site.  That is indeed the wire that does the signal to tell the car to turn on and then start.  The problem is that when you hit the start button it goes from +12V to ground, not the other way around.  My understanding of the EVO-One is that it would be sending a +12V to start through the yellow wire in the 6 pin harness and not a ground signal.  Is there any way to change the programming to get that behavior, or do I need to wire in a relay to convert the signal?

 

Just to double check that this was indeed the case, when I hooked the power probe to the car, if I pushed the - toggle (to send a ground signal) the car turned on and then when I hit it again it turned fully on, then I hit it a third time and it shut down, just like what the start-stop button does.

Are you sure you gave us the right service number? because checking this service number tells me that it has not been  programmed yet with the proper firmware and is still using the default factory firmware 4.18

 

You need to plug this into a Flashlink Updater-2 with a valid internet connection and flash it with the proper firmware and options.

I will check the firmware when I get home.  If I put in the new firmware then it will send a ground signal when it tries to start, correct?

The wire you need is a BROWN/ORANGE wire in the harness from the Smart key module and it is a POSITIVE 12V trigger connected to the Yellow (start wire evo one)

DO NOT CONNECT ANYTHING TO THAT WIRE YOU FOUND THAT SWITCHES NEGATIVE WHEN YOU PUSH THE PUSH TO START BUTTON.
