Help with code u0184

Driving home today my abs, bas and esp light came on. When I got home I plugged in my supercal that gave me 4 codes. Three were about my right headlights were drawling low power on both high and low beam. The last code was u0184 - lost communication with radio.

After clearing the codes out with the supercal, the u0184 remained along with the abs, esp, and bas lights. Radio works just fine. The last time those lights came on my wheel speed sensor went bad but the supercal picked up on it.

Anyone have this problem before?

There are three IOD fuses, and one main IOD fuse.
The main one is in the white holder in the fuse box. Look at the fuse to make sure it's not blown. Pull up on the holder to raise the fuse, then push down, making sure the fuse is reseated.

The other three are M10, M11, and M13. Make sure they are not blown.

If all is well there, here is some info for the U0184 code:

U0184-LOST COMMUNICATION WITH RADIO



When Monitored:
With the ignition on.
Battery voltage between 10 and 16 volts.
IOD fuse installed.
TIPM is configured correctly.
Set Condition: Bus messages not received from the Radio for approximately 2 to 5 seconds.



Possible Causes
CAN C INTERIOR BUS (125K) CIRCUITS OPEN OR SHORTED

TIPM NOT CONFIGURED CORRECTLY
RADIO POWER AND GROUND
RADIO
MODULE THAT SET THIS DTC

Ronjenx,

thanks for the info. Checked the fuses and they're good. Though upon a double check, I looked at the abs sensor I replaced a few months ago and saw that it had rubbed against the tire. Though it was a mopar replacement. The replacement was about 8 inches longer. I figure this is because it was an 07. The new cable was showing bare metal so that makes sense on the ABS, ESP, and BAS lights. As far as the fault code is concerned. All I can think of is it somehow tripped the ECU into thinking something was there when it wasn't.

This happened partially because I ordered 4" break line extensions and currently run a 3" lift (because I have a 3.5 awaiting shipping) Zip tying the abs to the brake line allowed too much slack and it rubbed against the tire, exposing metal.
I definitely could have routed the cable better as we'll.

Amen for jeep forums. This forum along with a few (crappier) ones have really saved my ass from time to time !
