Sounds like the automatic adjustment sensors/valve is gone or the shocks need replacing..

Have a check through what you did, it looks as though an ABS cable or sensor has been accidentally displaced or is now not close enough to the rotor to enable the signal.

When you have the vehicle checked for codes & the Parking Brake System tested ,you will have your answer Obviously there is a system fault eg: it isn't working correctly or at all

needs power steering fluid

ok lets do this in order
P0420 Catalyst System Efficiency Below Threshold (Bank 1) an o2 sensor bad usually before the Cat converter P0430 Catalyst System Efficiency Below Threshold (Bank 2) same thing but the sensor after the cat converter the c1734 people will say you need to replace a bad BCM, but don't,, once the O2 sensor problem is addressed , that code will clear , it has to do with the remote start b2090 has to do with power doors ,, this will drop off too once the system is rest , same with the last one you listed, If I was you I'd have the 2 O2 sensors checked, replace the bad one, or both, and have the mechanic clear all the codes, then recheck them
