2012 Ram 3500 with a U0184 OBDII Code

Post by m0unt41nm4n » Mon May 20, 2019 10:12 pm

Hi,

I installed a new Pioneer stereo with an RR and all the usual cables needed to run with the vehicle. The stereo works well as does all the AV, the steering controls, and rear entertainment system. However a scan tool tells me:

U0184 - CGW -- Central gateway - Lost communication with radio

This is an active code but no CEL. Is this normal, or should this code not be there?

Thanks in advance.

This is normal, since the OEM radio is no longer present. The only time we will send codes emulating the OEM radio is when it being absent causes other issues in the vehicle. This code won't cause you any issues. My husband has had the RR in his 12 Ram 2500 for nearly a year now and no issues, so I'd say you're in the clear.

Whew... well that's good to know. I was about to whip out an oscilliscope to trace the CAN bus. :-)

Thank you... you made my day!
