My friend owns the AEV converted Hemi LJ in the link below. Recently the cruise control has stopped functioning. The shop working on it has reached out to AEV several times, but has not received a call back.
The Jeep is displaying the code P0585. The possible fixes for this code are replacing the clock spring and replacing the cruise control switches in the steering wheel which both have been done.
The original cruise control setup on a TJ is vacuum operated, but a Hemi is drive-by-wire so it is controlled through the PCM. The thought now is possibly something wrong in the PCM. Everything else seems to be working.
A scan tool doesn't show any response from the throttle position sensor, so technically the Jeep shouldn't even drive, but it does. We obviously don't know much about how the 4.0 to 5.7 Hemi conversion works. The PCM reads that it still is the 4.0 six cylinder engine with no reference to the Hemi.
Any ideas on possible fixes? Any idea on how to get AEV to return phone calls/voicemails?
Thanks for any help.
