i just installed a remote starter ,could this be my problem

Question

I just installed a remote starter and now have these 3 codes ,coincidence or possible short ?

Answer 1

P0420 Catalytic below threshold Bank 1

P0785  Shift timing solenoid malfunction

P1860 Torque convertor clutch solenoid

This can be from the remote start system if you interrupted the ignition 0 which is power for the 2-3 shift solenoid and power to the TCC solenoid, at the transmission 20 way connector there is a pink wire if that power is interrupted or if the fuse blow open for ignition 0 .located in the instrument panel fuse (left side)
