:annoyed: Should I care?? It goes out, then comes back on...Also, I cannot find anyone to lube my chassis, as I don't (as in can't afford) want to take it to a dealer...Any chance these two issues are related??
Click the link below and you'll learn how to check the codes. Write them all down and post them here and we can tell you what's going on.

Well, at least I now know how to get codes, clear codes, and I certainly appreciate that!!

So here they are: C1252, 1255, and 1298...B3108 and 1141...C1780 and 1783...and some U's - 1014 1255 1301 1064 and 1128...Also P0404 and P0603....

I looked up what they all mean, and I have no idea what PCM or DIM stand for...some of them make sense to me though...although I have no idea what to do about them..

Any help would be appreciated....
C1252 - Left Front Normal Force Malfunction
C1255 - EBCM Internal Malfunction
C1298 - PCM Class 2 Serial Data Link Malfunction
B3108 - Transmitter Synchronization Failure
B1141 - Driver Pretensioner Loop Resistance High
C1780 - Loss of Steering Position Signal
C1783 - ICCS2 DL Left Output Short Circuit to GND
P0404 - Exhaust Gas Recirculation (EGR) Open Position Performance
P0603 - Control Module Long Term Memory Reset

Looks like there are a few issues to contend with. I don't know anything about diagnosing suspension system issues, but I would say about 3 to 5 of those codes are suspension electronics issues. The only one I can help you with is the P0404, which means you should clean the EGR valve and passages or clean the passages and replace the valve. You can read about how to clean it here:

Hopefully someone else will chime in here with ideas about the other issues, and if I was you, I would post this information in the Suspension and Electrical forums to see if any experts in there can help you further.

I thought the sensor was supposed to help identify what the problem was!!
No, the sensor tells the computer what the wheel height is for each wheel. That helps it decide how to set the dampening rates and auto leveling adjustments. If a sensor is bad, the computer will give you a code for a sensor, but those ride height position sensors are one thing you are not getting a code for. There are multiple issues, steering sensor, EBCM module, and a couple I have no idea what they mean. We need to know which of the codes are Current and which are History. You might have to check the codes with the engine running, preferably after a highway drive, to get an accurate picture of which are happening now and which are old. If that doesn't help us determine what's going on, it might be time for a dealership analysis. I'd never tell you to go to the dealership for anything, but this one is kind of a stumper. Hopefully an expert will jump in here to help you further, but an expert will need to know whether those codes are Current or History too.
