    C1253 ICCS2 Data Link Right Malfunction
    C1255 EBTCM Internal Malfunction

    VTD: B3031 Key Decoder Device in Assem Learn Mode

    I hate data codes. Not sure what to tell you except that B1126 might go away after 3 ignition cycles if you reconnected the plugs. Sounds like some novice was in the column or dash and forgot to replug them.

    Ya I wish it was a novice, more like a rookie to any car, I've found sooo many broken plastic clips and such, put it this way the dash pad, not one screw holding it down, they were all broke off from the dash pad itself. But you think maybe if I bought a new key from my local cadi dealer and had programmed the security codes would go away

    Not sure, but I doubt it. You need a pro like Ewill3rd (our resident Caddy tech) to have a look at this one. I'll PM him and ask him to stop in.

    Did you replace the EBTCM on the ABS module recently, or since those codes popped up? The 1252, 1253, 1255 and 1611 codes are all related to the EBTCM. They are the same codes I got when I replaced my 97 STS EBTCM with one from a 97 SLS.

    Re: Some codes that need to go!!

    One thing you can do is start by locating the RSS module (suspension). It should be in the rear electronics bay back of the rear seat.
    Make sure no one has been messing with the wires.
    A few of those codes point to that.

    The deployment loop open could be a broken SIR coil.
    I'd have to do some more checking on the other stuff.
    I'll be back if someone can bump this a few times for me.
    .... busy day.

    The silver box is the CVRSS module (suspension control module)
    That looks like a connection for an OnStar kit that was available for dealer installation.
    Could be something else but I see a shielded ground there.

    Re: Some codes that need to go!!

    A wire is sheilded if it has an aluminum foil wrapping, or a braided copper or steel sleeve between the conductors and the outer jacket of a cable. It keeps the inner conductors (inside the sheild) from picking up noise from the surrounding cables. Some cables are sheilded in pairs, some are sheilded individually some have multiple sheilds (think of a coax cable TV cable with an inner and outer sheild), all depends on the application. The sheild wire (wire attached to the tin foil or braid) is connected to ground to bleed of any noise the sheild pickes up.

    Re: Some codes that need to go!!

    ............shielding is an electromagnetic emissions "firewall" for interference both from within the cable and from without as in: radio or AC electrical interference "hash". The hum you hear when an audio interconnect cable has a poor shield ground................

    Yes, it's the OnStar connector. The car may have originally had the older analog system but that's gone forever and your car cannot be "upgraded" to digital OnStar by GM..............someone may have removed the old module. BUT you could go to a Bluetooth system with a lot of wire and install work.......

    Run your VIN through the VIN to RPO converter at the top of the main Seville page and see if the car had OnStar as delivered.
