2005 Dodge Dakota Laramie 3.7L (K) 4-spd (42RLE)

Hey yall. just replaced a transmission in this 2005 Dakota and Japser informed us that for warranty we needed to update the pcm. I hooked up our J2534 Autel Maxiflash elite, downloaded the software from techaurthority, verified the correct file more then a few times. hooked it up. it asked me to cycle the key a few times, said erasing. then downloading block 1. followed immediately by Failed. negative response 0x77 General Reject. verified firmware was up to date and the J2534 application was current, vehicle is no start now. did i brick this thing? do i have any options to try? i attempted to try again a few times with the same error. it always ask if i wish to apply the update but always fails. is it the Autels fault? i really appreciate any information.

Try it again as a PCM replacement, not re-flash. May need a SKIM code if it is equipped.

how do i do it as a PCM replacement? only thing i see is download the file from the site, load the application and select 2009 or lower. and the only option i have is select j2534, start cancel.

I don't have an answer for you butI would never flash a pre Can Chrysler with a Jbox, especially an Autel. Having said that, can you communicate with the PCM now? Let us know this and we can go from there.

yes i can still communicate with it. it just shows no loaded software on the ecu information screen.. i never knew pre can Chrysler where difficult. have done a few others mainly pt cruisers after the pcm fails. but guess i just got lucky.

If you can communicate with it or maybe even if you can't, it can probably be recovered with Witech. As Rick so adroitly pointed out, this vehicle does require Witech. Your problem now is to find someone's Witech that works lol

I use a DRB III, I’m not sure how to do a legacy Chrysler with a Jbox, and as others have stated, not sure its a good idea.

Standard fail with J2534 on pre-can Mopar. It can easily be saved but you or somebody else will need a DRB3. If you have a mobile guy with one he can save it

Sadly there are no mobile programmers in my area. Im trying to become one actually. I have ford vcm2 tech 2 and vw vagcom. And this autel came with an autel maxisys scanner, been working okay for the time. But I think im gonna just get a cardaq 3. Think that might work better?

If it is CAN, you need to find someone with a WiTech.

I also don't have an answer but a 2005 Dakota is CAN. DRB 3 won't help

Goddamn Rick you're right. OK, I will amend my statement to any Chrysler or at least before 2010

check your files on you computer. I remember we had a hard time on one Chrysler. The file was hidden. AppData, local, temp, low.

Hi scott, as a last ditch effort i have successfully recovered those pcms with a VCM2. Load the drivers for the vcm2 on that laptop and give it a go. HTH

I have used the j2534 app no problem for updates, drew tech products, I can not speak for the autel. I have found the early CAN ones to be quirky, Have you tried to disconnect and reconnect the pcm? I have a semi dangerous tip that is last resort only but has worked for me when chrysler pcm fail / and or no comm due to programming error. Key off , disconnect pcm key on, key off, reconnect, and…

Attempt another reflash with the ABS unplugged. Early in the Jbox experience with Chrysler I had this happen. Drewtech had a document about increased resistance issues and recommended unplugging modules on the BUS. Its worth a shot IMO .

As Mike P mentioned or the issue is your Jbox and or PC/software. Have you programmed other FCA vehicles with the same setup without any issues?

This vehicle requieres the DRB3. Maybe you can re-flash the pcm with the use of the DRB. Other wise you will just has to get one from the store, there are many vendor online that offer PCM already flash, ready to go. Plug and play. Good luck.

Hi Oscar: I don't believe that you are reading the chart correctly. It's also helpful to note that the MP2 wasn't out yet when your iteration of that chart was released. The one that you have is when they were migrating from the STM to the VCI-POD (wiPOD). At that point, the StarScan was already E0L for programming by over a year. HTH, Guido

Maybe I was not clear enough. The best way to program this units is with the DRB3. Jbox can also be used as well. Just not my preferable way to do it.

Hi Oscar: You were clear. I'm telling you that this is a CAN vehicle. A DRB-III is about as useless as tits on a bull on this vehicle. Guido

Oscar, 2005 ND Dakota is a CAN vehicle. DRB is not an option. As others have said, Witech is what works but on this vehicle, it might be too late

Hi Rick: Your statement requires a bit of "nuance". wiTECH 2.0 J2534 does not support that vehicle. This doesn't mean that it won't work. It doesn't mean that it will, either. Pre-2010 Chrysler products are problematic, no matter the interface used. I've had a CarDAQ lock the module up but recovered it using a different J-tool. I've had the opposite. I've had problems & lack thereof using…

Guido, you make a good point. When I say Witech, I automatically assume Witech 2.0 with micropod. It's pretty much all I have used since I believe 2013. I was fortunate to be invited to their pilot program, which I am still a part of. That has it's ups and downs. I was just pointing out that, like you so eloquently stated, A DRB 3 would not work. I have never had the "pleasure" of trying to…

Based on you saying that you selected 2009 and prior, I assume you are using the J2534 Flash application that has been sundowned, the most recent version of the software is integrated into wiTECH 2.0 J2534. To use the most up-to-date version you would need to install wiTECH 2.0 for J2534. I'm not saying that is the issue, but you will receive no official support without it. Check for network…

Hi Scott: Yeah, you can use a J-tool but why would you want to? I use an MP2 for one reason. I want it to work! I don't have time for putzing around and playing games like what is shown here. diag​.​net/file/f5e6kp1d5…

I consider the J-tool to be false economy with many (most?) OEM software products and I'm not into academic exercises much anymore…

Not saying anything is set in stone with my choices regarding tools. I'd like to become a proficient and effective programmer in my area and am trying to learn the do's and donts. From what I'm understanding FCA is a Royal pain in the arse and it's best to just get the factory tool. I haven't gone as far as broadcasting that I program but word is getting out from acquaintances and im getting…

Hi Scott: There really isn't anything "special" about FCA. They are what they are. If you attempt to equate them with other OEMs, you're just setting yourself up for disappointment. Actually, that applies to any OEM. They're nothing more than a hunk of metal, plastic and other chemicals. They don't care what you think or feel. Give them what they want or they won't work properly. I try not to…
