EVO-ALL not receiving lock input after we had to unplug and replug in.

Question

2018 Hyundai Elantra PTS.

We had the remote start working after a little while but we realized we had a bad/loose connection from the pts button so it would not let us press the brake even after pressing the PTS button when we would get in. We diconnected the harnesses and fixed the PTS connection issue and hooked it all back up. Now when we press the lock button on the fob the blue LED doesn't light up for when it receives the lock input. When we start the car the yellow led turns on like normal. I have checked most of the connectors, the 12v is solid and the ground is solid. We got the remote start for MPC so we do not have the flasher. Is there some sort of security feature that disables it when you disconnect the harnesses?

I assume the evo reads the lock input via the CAN bus's?

We are kind of at a loss for now, but will probably go back and check all the connections again at some point.

Evo-One don't lose his programmation when you unplug it, you have to follow the correct order when you unplug it, always disconnect large 6pin connector IN LAST.

 

Yes , doorlock feature is supported via CAN-Bus. When you unlock the doors, is the blue led of the module flashing twice ? Recheck your CAN connection if not. Then you can try to re-do the programming procedure if all your wire are ok. You have correctly used Diode to isolate the 2 wires at the PTS button ? Not connected backwards ?

 

Ive seen PTS connection error on some Hyundai/Kia that haved fryed Evo output...

Yes I used the diodes facing the proper way. Everything was working great until we had to fix the pts connection. The blue led was not flashing which makes me think it's a bad CAN connection. I'll double check that when I get a chance!
