I did my rear breaks sunday and after i finished and turned the car on the ABS, Brake, airbag, and check engine light came on. The car feels fine and runs the same just all of these lights popped. My rear left shock is completey snapped as we found out when doing the breaks. Like the bottom part of the shock just snapped off and is no longer connected. I will need to get the suspension fixed of course but just wondering if anyone could tell me anything about why the brake, abs, and airbag light is on? is it just from the broken shock or should i be worried about more? Car gets regular oil changes and upkeep, these never came on before this, could it be a sensor issue? helppp!

Thats your problem. Find out which rear wheel has the speed sensor then plug it back in or fix it.

Brake pad sensor wont cause the "trifecta" lights. Speed sensor will.
