Why does Heat and radio stay on when plugging in unit Nissan Frontier 2016?

Question

After installing unit EVO-ALL with Nissan T Harness, when I plug in the unit to program as soon as I plug in the first connector the Heat/AC and radio all power up? What am I doing wrong?

 

I did flash and set up the unit via the flash updater.

Answer 1

What t-harness exactly?

Fortin THAR-ONE-NIS2

in your initial post you stated evo-all, yet that harness only work with evo-one...

---

Apologize I did incorrectly state that. It is the EVO-ONE with the THAR-ONE-NIS2. Do you know why this would be happening with this setup?

---

did the issue arise after the installation? as in you installed it programmed it tested it and now this problem exists...

Sorry I missed that part, Aside from connecting the t-harness what other connections were made in the vehicle?

---

There were I think 8 wires total to connect, but the power to the radio and climate controls come on once connecting the t harness? Its almost like the t harness is wired wrong, but I didnt have time yet to confirm that.

How did you wire up the parking lights?

 

If you used a relay please tell me what wires went to pins 85,86,87,87a & 30.

I am not for sure if you really have an answer for me. Without anything hooked up (Nothing hooked up, nothing!), and plugging in the T-Harness from the ignition to the Fortin EVO-ONE the power comes on to the radio and the heater/AC controls. No other connections made, just plugging in the T Harness. Please if you do not have the answer or useful info no need to respond.

Your EVOONE has no ground on black wire or the module is damaged.

Derek is asking questions about your connections because a bad connections could damaged the module and do weird stuff like you are experiencing.

Fair enough, I wasn't trying to be a jerk by no means, and you guys probably understand it better. I will double check my connections for sure!

---

Verified connections, and all seem well. Also took new module and flashed with correct firmware, hooked up and the radio/heat controls do not come on, so my assumtion is something is wrong with the module?

Yes, more than likely has been damaged. If it does it again I would suggest calling tech support to verify your installation.
