My car (Mazda 6 2006) had issues tonight on the drive home. It jolted, the checked engine light came on, and multiple times all of the lights on my dashboard came on at once, and my speed gauge was at 0MPH. Codes that popped up when I ran my diagnostic tool are: C1119 (TCS transfer input signal failure), U0100 (lost communication with PCM), U0101 (lost communication with TCM), and U0121 (lost communication with anti lock brake system (ABS)). If anybody could help I would be eternally grateful. Also, ive been hearing a clicking noise coming from it for a while.

Best thing to do at the moment for free is get eyes on your wiring harness. Look for spots it may be chafing, pinching or pinched, or corroded/compromised somehow.

Wiring, check your wiring harness on the outside of the vehicle and where it enters through the firewall and fender. Could also be a computer failure

My father unplugged and checked the ABS control module for water but it was fine, that didnt fix anything. He's going to look further into it tomorrow

Hey guys, is it normal for rust/brown stuff/burnt to be in a singular wiring hole? (Not my picture, just showing the part it's in.)

Found the Workshop Manual online for my car, we tried to run a kilohms test on the wheel speed sensor from abs but we don't think we're doing it right
The one we are trying to check isn't showing anything but the other three seem to be showing constantly varying numbers

So, you definitely have a CANBUS issue, and your common intersection between those modules is the body control module. However, it's also very important to know exactly which modules are reporting each code when it comes to CANBUS diag.
