Hi, I really would appreciate some help. I have a 2.0 Mazda 5 sport, 2006. The car drives great, no issues except for electrical issues. Last week, I opened my car with the key when set with plip (alarmed). Had to rush to work so let it run down the battery to flat overnight. Day after I fully charged the battery, and when I reconnected, my hazards were flashing and all interior lights central locking and radio were completely dead. I managed to stop hazards by changing out that fuse. Now I have all the symptoms as before, except indicators flash quickly, but no green arrows on speedo binnacle or noise. Additionally, the OBD is dead. My headlights instrument binnacle and lighting along with windows and mirrors all work, so driveable.
I was advised to change ROOM fuse in engine compartment, which I did, but it hadn't blown. Sorry this is long winded, but I don't know where to look now, and I just want it sorted and some ideas where to start looking.
Thanks in advance

 

Could the problem lie with a blown relay? I wouldnt know where to start. Any suggestions gratefully recieved

 

If the OBD is dead, that indicates either a PCM, BCM issue &/or CAN BUS issue. I would recommend a specialised auto sparky or Mazda for diagnosis.

 

Hiya grim reaper. Thanks for the advice. I'll get it checked out.

 

did you find out what this problem was as I have the same on my mazda 5 and I am finding it hard to find out why
