Soon my Mazda last night I unplugged the battery to switch it out and once I plugged it back in the I got two warning light Soo I went to the display unit and went to warning part where it tells you what’s wrong and what the lights are for. The warning said Tire pressure systems malfunction and parking brake system malfunction. Can anyone tell me what to do to fix it?

 

Check & readjust your tyre pressures. We set them to 38psi at work.
Once done, turn the ignition on, press the TPMS button to reset the system.

Does this work for you?

For the park brake, start the vehicle, activate & deactivate the park brake a few times. turn it off, restart the vehicle & see if its gone.

 

I'm just curious, why a new battery in a nearly new car? Did you have an issue?
