App radio wont shut off draining battery - Pioneer DEH-1430R CD Player

try closing your app open apps by clicking left hand button then should come up with your apps what you been on at bottom it should say close app it draining your battery if that does not work you may need a new battery

The RAP relay RAP Relay

Ignition switch may be worn out or the safety switch on the transmission linkage when it is put in park may be bad ,

Check if it has a relay. The contact in it could be shorted. Replace the relay.

The battery itself may have an issue? You could try disconnecting the cable when you park and see if something is truly draining the battery. If it is you may notice a slight spark when you disconnect the cable. The alt may have a bad diode so it will charge the battery but drain it once the motor is shut off? Or it could be something like you suggested. The radio remembers its settings by being connected all the time. However a stock radio does not take much from the battery.

If this is an aftermarket radio, they hooked it up wrong when they installed it. Either way, this is a wiring issue. Remove the radio and make sure the wiring harness is corrected before installing again. Good luck!

sounds like a 12V drain on the system, like a trunk or glove box light that won't shut off.> Could be many. many other reasons why. The way I would find the draining circuit would be to remove the neg cable of the battery. I then would connect a 12V test light between the neg battery TERMINAL and the neg battery CABLE. With a 12V drain the light will shine. I would install into the light a 9V battery powered recepticle to hold computer and radio station memory. Then I remove fuses 1 at a time, then reinstall, at the same time looking for the 12V light to go out. Hope this helps.

test the alternator it could be draining your battery.

All newer vehicles have a safety battery shut off. Youll need to turn your key back to accessory. say your listening to your radio with the keys out, it will shut off after 10 mins so it dont drain your battery. dont worry about it killing your battery charging a phone...ect.

your radio is staying on? you have a bad door switch.the bcm does not see door opening and thus does not turn radio off. most likely the drivers door.
