The flash you refer to was to correct a dealer-installed TSB bug which prevented aftermarket diagnostic scantool access, which would also affect the SGII - however, the SGII problems are caused by the basic architecture of the KJ CRD intra-net, with a Bosch ECM talking to the DCJ\Mitsu TCM and associated xCM's and the Bendix ABS module - the problems don't appear to occur where the ECM is also DCJ
Won't help you for right now, but I intend to investgate this further, after I recoop from 4wks of hard labor, incl prepping (IP, gp's, injectors, timing chainset, ac, etc) a neighbor's '83 6.2L Diesel Sub for a trip to Kalifornia, down the Baja, and back again - just need to attach various rocket science apparatii to the several communication busses at the DLC for observation and analysis of the KJ CRD intra-net - as I have noone to drive my KJ while I monitor processes, I'll prolly jack it up and run it in place, as the drivetrain needs to be fully functioning in order to trigger any events - this will also help to reveal if the ABS is the culprit, as I suspect, as the tests can be performed with no braking events, eliminating any ABS interaction, and with braking events - those will of necessity be run in 4wd to get input from all wheel sensors
Why do I care? To prevent misinfo from DCJ dealerships and other "professional" sources from confusing the issues with the KJ CRD, which can and has resulted in damaged KJ's, and owner dissatisfaction and disposal of a perfectly viable vehicle - check my sig for specs of my rehabilitated runner.
For now it's all free, but rest assured, I will keep myself in check(s), soon as I open my shop, thank you very much.................
