Pioneer car stereo

This is an anti-theft measure and most likely cannot be fixed but you could try going online to Pioneer and see if they have a fix, Good Luck

You probably will need to call support for your car. You will need the VIN number for the car.
if it is not the factory radio, call pioneer.

If it was plugged into a surge protector, check the surge protector warranty. There are A LOT of surge protectors that will cover damage to items plugged into them through their warranty system. I've had full home computers and TV's replaced by surge protector companies to avoid having a hit to homeowners insurance.

I have the DEH-1200MP model super tuner 3 and it would not power up after battery died and was jumped. There is a fuse at the back of the stereo that I unplugged and plugged back in and then the stereo powered up. I had already checked all of the other fuses. Took me a while to figure this out.

Hi there,

Well you can please follow the below steps -
1. Disconnect your car battery. It is vitally important to your safety that you never work on any type of electronic in your car with the battery still connected, as this puts you at risk for electrocution.
2. Remove the old stereo by taking off all the dashboard panels surrounding your stereo, sliding out your old stereo head unit, and unplugging all the wires that are connected to the head unit. Discard the old stereo.
3. Take your Pioneer car stereo head unit and plug each of the positive wires from your car speakers to the positive terminals on the head unit. Take all of the negative speaker wires and connect them to the negative terminals on the head unit.
4. Attach the stereo's black ground wire to a metal bolt or screw located near where the stereo is mounted in the dash.
5. Connect all of the ignition power wires to your Pioneer stereo.
6. Take the harness connector and plug it into your car stereo. Now plug the antenna into the back of your head unit.
7. Slide the stereo back into the dash, screw it in place, and replace the dashboard pieces you removed earlier.
8. Reconnect your car battery, turn the car on and test out your new Pioneer car stereo. Please post comments for more help or information..........

Good Luck!!

Thanks

Car stereos typically have an "ignition" and a "battery" wire. The ignition wire is connected to your ignition switch, and only supplies power to the stereo when the car is turned on. The battery wire is connected directly to the battery, and always supplies electricity to the stereo -- even when the car is off. This maintains presets, clock, and other settings in your stereo.

It sounds like your battery wire was either not hooked up, or has come loose. On your stereo, a Pioneer, this wire is yellow. Locate the yellow wire on the wiring harness on the back of your stereo. This wire should be connected directly to your battery (or another source that gets constant +12VDC).

i have alpine stereo's in all my vehicles and i have had this problem. if you run a 10-14 gauge constant wire from the stereo directly to the battery the stereo will not shut down in protection mode. it is not the cd it is the stereo going into protection mode because of lack of current not voltage. i hope this helps after i did this i could play the stereo as loud as it can go until my battery died

did your battery die after you installed cd player or did it die because of some other reason. please first confirm this since wrong connections are the biggest culprit .best of luck.

It definitely sounds like it took a surge. yhe Power Amop IC in those things are pretty sensitive. Any decent repair shop should be able to repair it for under $125.

Hi, The "sec" could probably stand for security lock. It is a feature to discourage car stereo theft but is prooving to be more of an owner's problem when battery dies or are replaced or simply when disconnected for maintenance or whatever. The sad part is you have to get in touch with the original dealer of the car who would probably ask you for registration papers, proof of ownership (deed of sale), VIN, make/model/serial number of the stereo and/or other documents. I know its a bit of inconvenience but there is not other way since they have to check a database and fill in so many data themselves. I just hope the dealer is friendly enough. Good luck and kind regards.
