Help get these lights off?

[tenguns]

P0420 bank 1 but even when trying reset lights to get ABS/TRACK and the Christmas tree dash off, nothing works.

Want a clean computer before I start repairs. Tried battery disconnect x 3 hrs, tried zero point calibration, tried other youtube tricks but need some new hocus pocus / secret /:tap three time methods to get the lights off and start repairs.

Any help. Battery and 0 point... no effect. Not throwing codes now but lights still on.

p0420 indicates a physically bad catalytic converter. You will need to change it or install a cat cap.

you didn't explicitly say it, so i'm just wondering if you tried a cheap obd2 scanner to clear the code as that has reliably cleared all the codes on my 2005 over the last few years. i had this same code last year and it was caused by an exhaust leak near the cat. it was the only stroke of good luck i've had with this vehicle it seems haha
