Iod fuse My phone button doesnt work all of a sudden. No error message. Could this be a 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???????????

The IOD fuse is located in the IPM (Intelligent Power Module - a fancy term for the main fuse box) which is in the engine compartment right next to the battery.

The IOD ( ignition Off Draw ) fuse is a 60amp fuse located in the underhood fuse block in cavitiy j13 I beleive it's yellow...This is the IOD - Main fuse.

B2100 code. this is a bumm code ( P2100 cry) B2100 low battery.
three is no b2001 in the 7000 pages, just looked,

well what if its real and dont want to reset.?
yes, we do that, and see if t comes back. as most do.
the answer is same on all cars 1996 to now, heck back to 93 in fact.
answered 100s of time, here goes again.

1. press the reset button in the OBD2 scan tool, works 93 to 2016 all cars, in usa.
2. pull the cars battery neg lug for 5min., the can have the bad effect of losing all programming on radio, nav, and things. mirro loc, seat memory, on and on an on, pain.
3. or PULL the IOD fuse on PCM. fuse # PDC fuse 20 is IOD for PCM . this is the PCM memory wire, when the fuse is pulled the PCm forgets, stored error codes.

#1 always works and works best.

the free fsm covers all that. wk, jeep

i have this car so , its not new to me.

I had an issue where my backup lights stopped working. I was told to remove the IOD for 30 seconds, replace and test. Sure enough the BU lights returned! I see different values for the IOD, mine is a 20 amp in a 2003 Dodge Caravan SE, no electric anything and a 2.4L engine. Is this the correct fuse?

a jeep phone?

That fuse has nothing to do with the door. IOD stands for Ignition Off Draw-it's the circuit responsible for small amounts of battery power to keep computer memory, radio presets, the clock, and security system alive when key is in off or removed.
I don't know which fuse for the door, but not the IOD fuse.

A cheap solution is to remove the IOD fuse (under hood in power distrabution center) for a few minutes, which resets the BCM.

im not to good electrical but i would say you have a bare wire touching metal or something. maybe a wiring glicth.

IOD NR18 on in "power distribution center" behind air filter. Here is the link to photo: [url]http://www.ptcruiser.fi/ptgalleria/albums/userpics/Power_distripution_center.jpg[/url]
