99 Cherokee Sport 4.0L - What is the difference between flashing and programming?
Hello everyone, I'm a new member. My family has always worked at Jeep, my mom has always worked at Jeep, but this is the first time I've owned a Jeep. Recently I replaced a dead dead battery with a new one and reversed the charges. Three seconds later, a nasty smoke came out of something and I removed it. I switched the direction and reconnected and the interior power started, the doors were dinging and the jeep attempted to turn over but never could. I got a no bus signal on the dash.
The Chrysler/Ram/Dodge/Jeep dealership I have never been to called me and said my pcm was bad. They told me they have a source for pcm and the dealership markup price is 745. I called my family who works in parts distributing and she could get me one for 180 (60 refunded for pcm exchange). She sent it to the dealership and I got a call saying "the pcm is already programmed for another vehicle, we can't program it." Should a dealership be able to clear a pcm (if that's possible, I''m guessing it is) and then reprogram it if they have my original pcm? Also, is programming the same as flashing a pcm? The dealership told me they were going to charge me a fee for "flashing" when they originally told me the pcm was the problem and the price for the supplier of pcms. Are dealerships used to having a third party take both pcms and "program" them, and then get the pcm back, install it and then do some necessary separate "flashing"?
If anything I have said is true please let me know. I want to get the terminology straight before I talk to the service guy again tomorrow. I also want to know what typical dealership capabilities are in programming and clearing a pcm. And is flashing and programming the same thing? Thanks a lot for any help I will be back on the forum tonight.
