DOES 2013 FIAT HAVE A IOD FUSE

A dodge RAM truck, that?
RHR means what?
all radios (most) have wire called, 12vdc memory wire,.
if that wire is cut broken shorted or fuse to it blown memory will be dead. it is that simple.
or installed wrong, did someone do that?, or is radio stock like it was 2011.? then is fuse blown.
RHR I think is Dodge real radio name best I can tell (vast radios exist)
Dodge (FCA) calls those fuses, IOD.
there is one for the radio too, day 1 new out the door
and the factory pulls them all , just before the cars ship to the dealer.
so the battery is not a wreak on deliver.
Iignition OFF , drains, is the name or as we ETs call it memory power. and is.
this wire on radios since 1970, first transistor car radios with station memory, so 50 years now same story ..
main power and ground, IN.
memory power In.
antenna power.>>>out.
speaker.>> out.

a scan toll will also show DTC error for and IOD fuse blown
amazing no?
or lost communications DTC errors making radio fail.(in odd ways)
newer cars the RADIO is married to the BCM
and if IOD blown or comms fail
radio can not save memory.

here is the SM quote on this car dodge RAM 2011
U0184-LOST COMMUNICATION WITH RADIO
For a complete wiring diagram, refer to the Wiring Information. When Monitored: Continuously when the ignition is on. Battery voltage between 10 and 16 volts. Ignition Off Draw (IOD) fused installed. Totally Integrated Power Module (TIPM) is configured correctly. Set Condition: Bus messages not received from the Radio for approximately two to five seconds. Diagnostic Test VERIFY THE DIAGNOSTIC TROUBLE CODE (DTC) IS ACTIVE Make sure the IOD fuse is installed and the battery is fully charged before proceeding. Turn the ignition on. With the scan tool, read the active DTCs. Is this DTC active? Yes (Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM)/Diagnosis and Testing)(Refer To List 1) and perform the U0184-87-Lost Communication with Radio - Missing Message diagnostic procedure. No (Refer to Non-DTC Diagnostics/Communication - Diagnosis and Testing)(Refer To List 2) and perform the Stored Lost Communication DTCs diagnostic procedure. List 1 28 - DTC-Based Diagnostics / MODULE, Totally Integrated Power (TIPM), DS/DJ/D2 - Pickup / Diagnosis and Testing 28 - DTC-Based Diagnostics / MODULE, Totally Integrated Power (TIPM), DD/DP - Chassis Cab / Diagnosis and Testing List 2 29 - Non-DTC Diagnostics / Communication, DS/DJ/D2 - Pickup / Diagnosis and Testing 29 - Non-DTC Diagnostics / Communication,...

as you and see , you can not fix modern cars lacking a scan too.
can not. (even 10 computer in the car) see this???????????

Have you checked your IOD fuse ? Quick Tip Signs of blown IOD Fuse on Chrysler Dodge Jeep Fiat or Ram...

Hello, please check all fuses first, if ok under hood I believe on pass front junction box locate the (IOD) fuse which will be labeled (IOD) on box cover and in owners manual fuse location and amp size. It may be a different color than all the other fuses. Pull the (IOD) fuse out and wait for a few minutes and reinstall. Try starting vehicle. Also when alternator problem addressed make sure main 40 to 80 amp max fuse is not blown out. Just to be on safe side recheck battery ground and other ground wires that may have been disturbed during repair. To check glow plugs if all else fails right rear top of engine is coolant temp sensor, disconnect sensor, this will cause ECU to think its cold and energize glow plugs, and allowing glow plug light to be illuminated.

With the key off, remove the radio fuse from the fuse box, start the car (there should be no power to the radio if you got the right fuse pulled), turn turn the car off, then then put the fuse back in. That should reset it.
In my 2013 Fiat 500 it's the 3rd fuse up from the bottom, on the left side of the bus. 10amp, red fuse. (If you're unsure, use the web to look up a map of the fuses for your make\model\year. Don't justt start unplugging fuses... you may strand yourself.) -Good Luck!

Check the IOD fuse in the under hood fuse block. If its o.k. then there is an issue with the IOD (ignition off draw) circuit. I should be able to get you some wiring info if you need it.

The IOD fuse is missing or burnt out. IOD is "ignition off draw" which serves as the dome lights, radio memory, locks and other things powered with the key off.

try testing for power at the headlight if there is none u should check the fuses

It's the IOD fuse. Trust me, I just fixed the exact problem on my '98 not ten minutes ago. The fuse is located in the fuse box inside the driver's side door. It will be the fuse on the bottom and toward the front of the panel with a black cover over it. Just pull the fuse holder straight out and snap the hinged cover forward to expose the fuse. Just a standard 10 amp automotive fuse and you're back in business!
