You could consider: skim key module as a possible cause.. check this informaiton https://store.allcomputerresources.c...im-delete.html

I am having a similar problem with my 2007 JKU. Have you had a chance to install the ignition switch yet? I have replaced the battery, the terminals, and most recently the starter and still having the same issue. The ignition switch was where I was headed next. Just curious if you have installed it and what happened. Thanks!

JKJB

thanks for the link. started digging into that and after some googling found my jscan app has an option to disable the wcm but i dont really feel like being a guinea pig for it lol.



yep and still have same problem.

JKJB

oh yeah theres this tsb as well

i contacted jscan about the wcm disable feature amd they said: "It won’t work, disabling skim is much more complex on JK platform." lol, at least they are honest.

If going this route, can you still drive the vehicle or ids it out of commission until you get the module back? Thanks!

Nevermind, I just thought it was the skim that was removed. The vehicle won't run until the PCM is reinstalled. Also looks like you never reinstall the skim after this is done. Does the skim delete affect they fob's ability to remote lock/unlock the vehicle?

Thanks!

JKJB

no because you have to send them the pcm, not the wcm. im in canada and also have a hemi swap so its not something im gonna do but if you do please post back how it works or if it works haja

Alright. Still thinking about it, but if I do, I will definitely let you know. Thanks
