Hi. I recently purchased a 2010 mazda 3 second hand with some electrical problems. I got a really good deal on the car for the shape of it but the electrical problem has me stumped. I’ve narrowed it down to either the bcm or pcm. Maybe both. Looking for opinions. I will upload the pictures of the codes which there are a lot of when I get home from work. Essentially low power to pcm code, low power to bcm, abs module, power steering module. All of those modules mentioned have erratic signal from pcm codes as well. Thank you in advance.
