When I bought the car a week ago, Check engine, abs, exclamation triangle and brake light was on. OBD2 scanner read, catalytic converter codes A1 and B1. Tried clearing would not clear. Came home, while physical checking, saw a power steering circuit wire, leading to ABS control module clip (coming off from side wire harness) connector was disconnected. Fixed the wire. My battery wire was removed. After fixing replaced battery connector, CEL gone. Car was kept running for an hour, CEL came on again, this time with oxygen sensor codes.
Now driving the car, about 50 miles CEL hasn't come back on, still reads not ready on OBD2 scanner, and still the TCS, ABS, BRAKE and exclamation triangle on.
Any ideas?
Second- my radio is making a screeching noise- any diagnosis? It looks apparent there was a sound system which was removed, could be a potential culprit. Checked radio connectors- all seem fine.
The central lock doesn't work, and the power lock button doesn't work.
