Okay. I've tried everything.

Radio was working. Replaced the ECU in the car with one that wasn't bricked. Dealer reprogrammed the new ECU since the immobilizer was active due to the key not being recognized.

Got the car back, and the radio doesn't work. Radio was working with the old bricked ECU, and Radio was working with the new ECU BEFORE it was programmed.

I've replaced fuses
Tested voltage to the faceplate
Replaced the faceplate, and the headunit

Radio and little LCD doesn't turn on. I'm going to explode. WHY? Dealer said they thought it was the faceplate. Replaced it with a new one. noooope.

FFS HELP ME

 

security key.

 

What?

 

You have an issue with the programming - the dealer should know how to reset the ECU (sounds like the radio thinks it is stolen and has turned itself off)

 

As far as I remember the stock radio, even tho no one ever wants it, has a security feature "build in"

at start up, it check against the Car's info to see if it's still in the "same car", if not, it will not start.

the manual should have a sticker somewhere that tells you the "Security code/Key" for the head unit. you need to enter that information by pressing the number button on the head unit.

I think this is the issue you're having. or like Stealth said there is something wrong with the programming, cuz the PATS info should be the same ...

 

Any instructions on checking this radio code? I so not have.the manual but if I can get this thing to sgow any lofe I will gain some confidence

 

hmm I'm not sure if Mazda even has the info so if u don't have the head unit's code then ... good bye to the head unit ?

 

Well even if I had it how would I enter it?

take it back to the dealer. they are the only ones that can help

 

off subject my fellow friend..I noticed it says ask you about the fuel pump removal tool..I have tried several ones..and the hammer/screw driver method...nothing worked..do you actually have a tool that works??
