Hello, I currently just bought a 2016 mazda cx-5 2.5l sport 2wd. I bought the car with a dead battery. I had a car battery from another vehicle i had and i put it in and there was no lights on or anything. Went to walmart got a battery, Battery is a maxx-35n. I go to start the car and it started normally but now i have a engine code which is p0882 and the lights are dsc malfunction, keyless entry malfunction, tpms malfunction and parking brake malfunction. I put the battery that made it all go away and it still there with that battery too. Any clues on what could be causing those errors?

 

Does the car run Ok with all those lights lit up? Usually that's the kind of dash display you get when the engine goes into limp-home-mode until the ECU is reset, usually by turning the engine off and restarting a few minutes later.

 

The doesnt seem to be in limp mode. I am still driving it and on the freeway too. Its been like this for a few days and the car has been turned off and started many times. Tried disconnecting the battery and putting in back in. Same results.

 

And you're sure the cable clamps are good and tight on the posts?

 

Have you used a scan tool to clear all the codes?

Also, did you see the engine running Without warning lights before buying it?

 

Yes, checked the clamps and its on good. I did clear all the codes which was only the p0882. My code reader cant clear the malfunctions.
