acperera

I did front suspension (struts, ball joints, tie rods, lower control arms) and all four brakes (pads and rotors) in my Lexus RX350 2009. Didnt do the wheel alighnement yet. Repair work was done one side on one day and other side on second day. After second day when I started to drive check engine, VSC off, and Traction control lights came. When i scanned P0441 and C1201 came. I erased codes, removed battery for a while, changed the gas cap to a OEM new one. Still the lights are ON. What can be the problem?

Google says the c1201 might be something with abs. I'd look over your brakes again.
How are they handling?

I did all of these last year and didn't have any issues.

Those lower arms are fun aren't they?

Did you raise your engine for the control arms?
May have knocked a hose or something loose.
