Can someone please help me! My ride will not start..everything is working fine in the ride lights,radio,power all fuses are good & Spark plugs.. I have a Cobb tuning and have checked codes. Has anyone else received this code
ECU
U0i67
Immobilizer communication error

 

Does your fast key have a dead battery?
Have you tried manually inserting the key into the ignition?
It's been a week. Hopefully you figure it out.

 

Have you tried to check fuses to see if one is throwing everything off...

 

Hey buddy it's still a no go. I'm really thinking I need to take it to the dealership. I was hoping I can clear the code but it won't clear with my Cobb access port. I've changed my fast key battery already and also tried the regular key in the egnition. Wen I do that I won't even get a crank. But when I try it with the fast key the car will crank but still won't turn on. I've already installed a new battery also thinking it might have been that but nope...sucks man

 

I wish I was more mechanically inclined to help ya, but unfortunately I'm not. Maybe a bad starter or bad ignition contact or something. Just seems weird it won't crank with an actual key, but attempts to start with FAST KEY
I'd go with having some one check it out, no since in stressing yourself out too much and keep us posted!!

 

The metal key still needs the 'mote to start.


Do you have another remote to use?
If not - tow to dealership (and buy TWO remotes).
