Hope it's not as bad as it looks.

HELP guys! :o

ABS C1282, C1288

DDM B3833, U1301, U1713, U1716, B1245

IRC B1271. U1327, U1000, U1064, U1065, U1160, U1016, U1129

SDM B1000, U1016, U1096, U1040

TTM U1983, U1016

Any of these have anything to do with that 'Service Stability Sys' error I got a few days ago?

Thanks...

The code groups you've listed are as follows:

ABS Antilock Brake System (Chassis Code)

DDM Driver's Door Module (Body Code)

IRC Integrated Radio Chassis (Body Code)

SDM Sensing and Diagnostic Mudule - Includes airbag crash data (Body Code)

TTM Tilt/Telescoping Steering Wheel Module (Body Code)

The ones I'd look into re: your Service Stability System error are:

C1282 Yaw Rate Sensor Bias Circuit Malfunction

C1288 Steering Sensor Circuit Malfunction

The "U" codes are network codes (mostly loss of communication codes). These are most often caused if your battery has been disconnected or if you have a bad ground someplace. I would clear them and see if they reoccur.

Hope this helps.

You didn't give us two important bits of information: are all of these History codes, or are any of them Current? And, do you have any complaints, such as the radio not working, the air bag light on, or one of the other lights? Does the car start in second gear? Are there any messages on the DIC? The Service Stability System message probably comes from the ABS codes, but that's it.

I've seen a menagerie of codes like this from power washing under the hood or under the car, a bad battery cable or ground, or starting the car with a low battery or bad battery cable. Usually when you have a low or bad battery or a battery cable problem you have several codes complaining about battery voltage below 9 Volts, and I don't see that here. I see a lot of complaints about the radio that aren't common. My guesses:

a) You just had the car detailed, and that operation started with a power wash.

B) The radio was just serviced or changed, possibly to an aftermarket model or a replacement from a salvage yard, by someone other than a dealer.

I would follow Poobah's advice and clear all the codes from the A/C panel and see which ones come back.

I was wondering what history meant because ALL the codes says HISTORY.

Does that mean I should clear and try again?

Sorry guys, never done this before.

No lights on cluster are on (airbag, engine etc...)

The Service Stability SYS was the only error I got and it hasn't come u since that day.

When a fault condition has been detected since you turned on the key, it is listed as Current.

When a code is listed as History, that means that the fault wasn't detected since you turned on the key. That may mean something is intermittent, or it may mean that the conditions for setting the codes, such as running at less than 1/4 throttle for 5 minutes or some such, haven't been met since you turned on the key.

A History code can cause a fault light or the check engine light to turn on. Some of them will go off after driving the car a few times if the fault isn't detected again, while the History code will remain in the computer for much longer.

That's why I recommend checking the codes after driving, before turning the key off. If you turn the key off, then on again, or you walk up to a parked car and turn on the key and read the codes, you can't tell what's current. I check mine once a week or so when I'm stopped at a traffic light.

I would clear the codes and not think twice. Like I said in the other thread, I got a steering wheel position sensor code once before, but cleared it and it never returned. This seems to correlate with Cadillac's recommendation that unless it's a persistent code (indicating a bad sensor), to not worry about it. Maybe it's a small software glitch/issue or something.
