2013 Sorento ex, while playing radio, with ignition pressed once for assessory, car makes a single beep every few minutes, what could this be

the chime can be from a few systems that may have a fault going on --seat belt female connection -seat weight switch-turn indicator left on - low fuel-door open -air bag -lights left on -etc

No such thing as a single ECU diagram. Wiring diagrams are arranged by system, not component. See this post on how to get the right wiring diagram How to get car wiring diagram Ricks Free Auto Repair Advice

Just a thought , is the indicater still in the turn position, this will operate the parking light so the beeps are letting you know the lights are on, if not make sure all windows and sunroof are completely closed , disconnect the battery a wait for the power to drain down for a few minutes before reconnecting, this may reset any malfunction, otherwise get the OBD read as may give a code to the problem

It's a safety feature. telling you that you have left something opened or not done some thing. Area's are lights, key in ignition, seat belts, and doors. A bad sensor some where. Body control module diagnostics can find the problem.

Remove the oil jug and try again.

I just think that you have it set to SIRIUS and have no Sirius subscription. Just press the radio button on the dashboard to go to classic AM/FM mode.

We experienced an intermittent problem where the entire audio system on our new 2013 Kia Sorento would fail to turn on at all after a brief stop (at a thruway rest area) on a long trip. When it happened twice the dealer replaced the entire unit and we had been trouble free for almost a year when my daughter reported something flaky happening to the radio recently again. I am keeping me eyes on this problem once again.

According with the Owners Manual:

* Setting the Time for Radios without Radio Data Systems (RDS)
Press and hold the HR or MIN arrow for two seconds. Then press HR until the correct hour appears on the display. Press and hold MIN until the correct minute appears on the display. The time may be set with the ignition on or off.

* Setting the Time for Radios with Radio Data Systems (RDS)
Your radio may have a button marked with an H or HR to represent hours and an M or MN to represent minutes.
Press and hold the hour button until the correct hour appears on the display. Press and hold the minute button until the correct minute appears on the display. The time may be set with the ignition on or off.
To synchronize the time with an FM station broadcasting Radio Data System (RDS) information, press and hold the hour and minute buttons at the same time until RDS TIME appears on the display. To accept this time, press and hold the hour and minute buttons, at the same time, for another 2 seconds. If the time is not available from the station, NO UPDAT will appear on the display.

RDS time is broadcast once a minute. Once you have tuned to an RDS broadcast station, it may take a few minutes for your time to update.


Hope this helps.
