    Delphi DS150E Error codes.

    Scanned my 450 ESP system and two error codes have shown up. They are:
    C12CF Inlet valve rear left
    C128F Inlet valve front right

    Does anyone know what they refer to?
    Also, the scanner will scan all sections but not the ABS section within 'brakes' though it will scan the ESP. When attempting the ABS it throws a 'can't connect with' message which is odd as it connects for the other scans.
    The nearest I got to an ABS scan was with a ISS (all systems) scan but it got stuck half way through the power train and brake scan and required forcing the lap top to shut down Delphi as it wasn't 'responding'.

    I'm trying to track down why my three dash lights (brake system, ABS, ESP) are on and won't go off. Clearing the two codes saw them immediately reappear.
    Any ideas as to what the codes relate to and why my scans aren't complete?

    (Delphi DS150E on Windows 7).

    They're are other causes (brake pedal switch, fluid level, steering angle sensor in steering wheel).... but I think you've got an ABS module problem methinks , the inlet valves are related , not being able to communicate, the lights, are all pointing to a problem in the ABS module imho. It's not unheard for them (in general, not just smart) to have problems with internal electrical connections... dry joints etc etc

    Freakishy expensive to buy new, but there are specialist companies that will overhaul/fix for much less (<200)., or if you're handy with a soldering iron you could do it yourself.

    Probably not really helpful but I can do a full ISS scan on my 451 CDI without problems.

    I suspect you may be correct.
    Fluid level (and connector to level sensor) is fine. When I've had a brake switch fail it was fine until pressing the pedal (1st gear engaged by another method) when dash light would come on. Possibly steering angle sensor - but I thought maybe - like a brake switch - no dash lights until activated ie, wheel moved. Could be a permanent internal fault I suppose.
    Can't the codes be used to narrow it down a bit though?

    As is a steering angle sensor.
    Two valves simultaneously failing on ABS unit - likely?
    I seem to recall a recentish thread (maybe on Maniacs that I can't currently access) and from memory some ABS units have removable and/or repairable modules while others don't. Mine is 2005 Mk7.
    I can solder wires - electronic components I'd prefer not to.

    Any more suggestions welcomed. Really don't want to go into a Scottish winter (it's already icy here in the mornings) without ESP.

    You'd be soldering connections on a PCB, it probably won't be the valves but the connections to them.

    Here's a sample video list (not a smart car obvs)

    and here's a generalised diagram that might explain why it could be both fronts (or rears) together, just depends where a common connection might be:

    Thanks R-I-S. I'll get back to this tomorrow.
    BTW, I Googled the codes and found them on a GM Hybrid page. There too, they point toward ABS. 'ABS dump solenoid shorted' for C12CF and 'ABS regenerative axle pressure sensor raw offset sensor error' for C128F.

    I noticed you have codes for diagonal wheel problems & the diagram Reinaldo posted shows the abs system wheel cylinders are paired up diagonally too.
    Is this the same on a Smart?
    Just an observation.

    Nicely observed. Devil is in the detail - always!
    Had another go at a scan today but still couldn't get the ABS part of the brake section to scan - only the ESP part. Do you think there's anything to be gained by scanning the ABS part or is what I have as much as I'm going to get? Someone sent me a load more files that work with Delphi scanner so once I've them sorted (zip files) maybe it's possible.

    Only other thing of note is that one of the codes flages as 'permanent' the other 'intermittent'.
    I also checked the four ESP fuses - all OK.

    I've got a Chinese Delphi unit too, but I don't think it scans the ABS as my cars are earlier models with the ZEE not the SAM, also no ESP just TRUST+ & so has limited functionality.
    I think my ABS only does the front brakes but not totally sure.
    Out of interest, what files have you got?

    The files - as much as I know so far is that the guy who gave me them got them from a Wurth disc he bought (he offered me the disc also) and apparently they enable the Delphi scanner to do more on more vehicles.
    They are zip files and took some time to download - he posted them to daisypie (similar to dropbox) and I got them from there. If you want them I guess I should ask his permission and PM you the link, or I could e-mail them but that would be slow I think.
    So far I have them on the wrong lap top so I've still to transfer them to the Win 7 one and figure out how to open/use them (I have winrar). Are you good with zips (sounds like a question that would have been asked here 10 years ago!)? If you are and fancy the files and giving me some guidance - I'll ask for that permission. Doubt he'l deny it. Especially if I have someone else to bug with questions. Let me know if you are interested.
