upon turning off i received a service theft system warning. Full power lights, horn (not w/fob though), radio, ect. prob is radio stayed on even when the key was out and door was closed. my codes are plentiful. i have msm u1000, ddm u1000, rfa u1000, rim u1000, rss 20620, rss c0662, rss u1000, sdm u1016, ttm u1000, ipm b0429, ipm u1000, and amp u1000, oh and ipc u1000. seems quite the nightmare. any help guys (sub, ranger,ect.) please.

Codes are meaningless without definitions. But the first thing I'd check with all those U1000's is the battery voltage/connections.

ALL those codes except one point to a disconnected or bad battery - low voltage and data hiccups. The B 0429 says your door for rear seat console ventilation has a problem.

Use this and post the codes and definitions, not in texting style, please.

If the radio was ON and you left the car it might stay on until RAP drops out.

Yeah, class 2 communication failures mostly. I took it to a small shop and it was diagnosed with a bad starter... @350.00 just for labor. I was maybe thinking the key or the ignition switch, but what do I know. Could it be the starter?

Oh yeah, the battery is about 3 months old. So, I kinda ruled that out.
