Codes
My 2003 is throwing up the following codes
RTD U1000 H
TCS C1283 H
TCS C1230 H
Any help would be great. Sitting at idle nothing comes up. Once you start driving the service ABS comes on then the traction message comes on.
I took it to a parking lot. Drove around at low speed until the traction warm up completed thinking maybe that might due the trick but as soon as I left and got moving it happened.
I also cleared/reset them and they still keep coming up. Not sure what to do now. Thanks in advance!

Not at home now. The RTD is Real Time Damping (variable shocks) and I don't think that would cause the other 2 codes but don't quote me on that till I can verify.
C1283 is Excessive Time to Center Steering and would be related to the SWPS. Have you done anything that would have affected the steering column? When driving straight does the steering wheel seem to be correctly centered or off some? If the SWPS is bad at least new ones are available for 2003. Any alignment work done recently?
Can't find C1230 on line. Verify that number is correct. Will look in the 03 FSM when I get home.

1230 It's in your traction control system. The number didn't show up on my listing. The closest, 1232 through 1236 or 7 refers to your wheel speeds don't match up. That usually means that you're gonna buy a wheel speed sensor. I don't know how much they cost.
Usually I google the code, (C5 code ????). I let my search engine work for me. It usually comes right up. If I need a part, I go to Rock Auto (on line) first because in my experience, they are the cheapest. The shipping is timely too.
Good luck with it.

No problem. Here are the diagnostics for your C codes. Just give the site some time to open. No need to sign up to view.

Here is the U code info.

I have not looked at these in detail yet. If you need any wiring info or schematics just let me know. If you need any other help let us know.

Thanks for your responses. I drove it today and the steering wheel is dead on and tracts perfectly straight.
I am going to get into the speed sensors a bit later today. Hopefully get this figured out.
Thanks again!

Ok. Checked sensors. Checked plugs for sensors. Everything looked good. Went for drive immediately active handling abs and traction control lights came on. And that is the usual. However, checked codes again and now I am getting
TCS C 1233 H a long with the
TCS C 1232 H.

All the codes I've seen you list so far are H codes they are history codes... You need to clear the codes go for a drive and then retrieve the codes BEFORE you kill the car... that should give you current codes.

Check the EBCM connections and make sure they are clean and seem aligned for good contact.
If that does not help you are going to need to measure VSS resistances and voltages in the diagnostics I provided.
Are you still getting the C1283 code?

I did see and read that link thread.
I am now down to just one code.
TCS C 1232 H
I have parked and cleared that code a couple times but it just keeps coming back. A long with the abs, traction, and activs hndl lights. I am thinking maybe I will change the harness as that seems to be the easiest and most likely the problem. Thoughts? I don't want to throw parts at it but the alternative is quite pricey.

For kicks and giggles... unhook your battery for about 30 minutes and see if it comes back...

I have an HVAC code that WON'T freakin go away... I clear it and it comes back....but, the A/C works awesome so, I have just resigned myself to the fact it just enjoys jacking with me and I now ignore that code and will as long as everything is working fine!

There is an interim connector near the battery area if I remember correctly so we can check each way from there, to the EBCM and to the sensors.

I would not do that yet. Measure the sensor resistances and voltages first. If they are good lets check for continuity in each wire to see if we can find a fault. I can provide the schematic and walk you through doing that.
