I just started having this problem today where all my lights came on, ABS BRAKE VDC and SLIP are all on at the same time and my speedometer stopped working. Any ideas what can cause this?
I hooked up a scanner and got the codes
U1001
P1212
P0500
P1212
U1001

also my speedometer works momentary if I turn off the car and turn it back on while driving

2003 BASE 6spd

Look them up here...

you'll find

P0500 Vehicle Speed Sensor Malfunction

P1272 A/F SENSOR 1 (B1) No activity

U1001 is a CAN communication line failure.

The 1272 doesn't seem to be related to the problem other than the U1001 may explain them all if the ECU is failing or there's some wiring harness problem.

What should I do?

Well I was driving it and I turned the key off while doing about 65 mph for about 2 miles and turned it back on and it started working again till I got home, but now my check engine light is on and i'll have to wait till tomorrow to find out what codes are there now. What could cause this?? The initial problem started after I spun out in a parking lot on accident

Lol get 305's On the rear less likely to spin out by accident...

Spin-out in a parking lot? Try disconnecting the battery overnight; I spun off the track last month, went sideways through the grass for about 200 feet or so, and my VDC and CEL lights came on. Didn't have my scan tool with me so disconnected the battery and the lights went out. Checked later and no codes were stored so

It was 1212, not 1272? 1212 is CAN problem at the TCS/ABS module, combined with the speed sensor looks to be connection or module is dead. CAN is really cool wiring system that only uses 2 wires to send high speed data to the whole; like a train between each of the modules. Double check your battery; ABS module connections and grounds.

I checked all the speed sensor wires and pulled off all my tires to look for anything that may of come loose but since then I reset my CEL with a handheld and it hasn't come back on yet. I hope nothings damaged because those sensors are really expensive lol. And as far as CAN where would that unit be located?
