long story short: i want to look for evidence the alternator was not the source of the recent issues. see this chat for deets<\/a>.<\/p>\n\n\n\n

need 2 items to go deeper than a simple “check codes” with my cheeepy odb2 bt adapter 1<\/a><\/sup>(which i cannot fucking find!! it was in the car, no longer in port when recently did this work;). is blue);<\/span> <\/p>\n\n\n\n

    \n
  1. an sgw bypass cable<\/span>
    \"\"<\/div>; inserts in the 12-pin connector allows you dongle to talk to the can bus at a deeper level. 2<\/a><\/sup>but why can’t yu just plug your odb2 dongle direct to the 12-pin cable? does the system need to have the odb2 plug attached?<\/span><\/li>\n\n\n\n
  2. software that understands the jeep\/chrysler\/? specific codes; jscan<\/a> is free if no liscence purchased; 3<\/a><\/sup>requires license for the full ability to set stuff, but i will try it without liscsance for what i wan. i think<\/span><\/li>\n\n\n\n
  3. an odb2 dongle that is known to be compatible<\/a> this one<\/span>
    \"\"<\/div>(specifically sez jeep KL version?\/model? is supported;) with the fuckery jeep does to the signals or code or both?<\/span>
    \"\"<\/div><\/li>\n<\/ol>\n\n\n\n
