After installing my evo all with t harness the 3x lock starts the car but throws on my check engine light. When I scanned for the code it show no active code, but the lights on my dash. I'm not sure what's being done wrong since I can't locate a code to reference anything to.

2017 Hyundai Sonata throwing CEL

Fri, 26 Jan 2018 18:12:06 +0000

I did an install on a 2017 Hyundai Sonata. I did the install and everything worked perfect. Flashed it to the latest firmware. 1 week later the check engine light is on and he is blaming the remote start and is demanding it torn out, which is not going to happen. I know a number of the chryslers need the firmware rolled back because of timing of signals on the can bus. Can this most likely be fixed by changing the firmware setting? I have not checked the CEL codes yet, and the vehicle is an hour away. I also do not have the serial number on hand, It was done with an Evo-All and Viper 4806V. I have done dozens of installs with this unit combination and never had an issue. I would really appreciate any help.

I have evo chart6 installed into my 2016 challenger and now only on remote start 3x lock, i get a check engine light, no code comes up when checked? I can start car with push button and the check engine light is not on. What is the fix?

I read on another dodge check engine light problem it was noted to flash with 74.18 Will this fix the problem?

I have flashed unit to 74.18 but I still need to know an answer as my son will put the unit in his car and I will need to know before I give it to him.

thanks
