Pass Thru Pro II BEWARE!

[sbreland73]

My penny and half: a few years back, I worked at shop that did extensive diesel repair, and even those techs would scream that the Cummins contoller on some model years (which is NOT Chrysler software) does not play nice sometimes, even with a DRBIII.

my son and i have a mobile diag.and reflashing buisiness.the problem IS with chrysler on these vehicles.chrysler tried to marry a cummins engine pcm with a ngc controller.I have the factory chrysler tools and i won't do these because it's a software issue between these controllers.the dealers are having problems but they have a stock of computers they can throw at the problem and we don't.we use a pass thru pro and a standard i-flash daily and don't have any problems flashing. alot of times you need the factory tools to finish the configurations.some gm modules will only program old school.had a 2005 trailblazer passanger door module that will only program tech2 remote.this is not all plug and play like alot of folks believe.takes alot of research and patience to learn and the auto manufacturers are less than helpful to say the least.the 2 tools i mentioned are verified through the oem's websites.every manufacturer has specifications listed.you can find links through nastf.Happy reading.

Did you install the tool box. In big red letter it tell you not to perform reflash on on dodge cummins modules. it will not write the vin back to the module. Not the tool the user. This is why i say read and read and read somemore before trying to flash promgram.

Good luck.

You are absolutely right.I went through the same **** and after countless hours on the phone with technical support,they arrived to the conclusion that i couldn't flash Chrysler products at all.I bought a Verus with the Passthru Pro2 mainly to flash Chryslers,being a Chrysler tech i thought it was a good idea to have this tool...god i was wrong.I tried to flash a 04 Grand Caravan using the scanner and guess what??..not enough memory on the scanner to do it,then i bought a laptop loaded with Win7 just to find out that Chrysler don't like the Passthru Pro2 any more,great! Chryslers is not the only issue here,i had the same problem with Nissans,GMs,Toyotas where the flasher won't communicate with the vehicle due to incompatibility issues.Nothing pisses me off more than to find out i won't be able to flash a vehicle after i paid for a freaking subscription and there's no way to get my money back.i ended up selling the Passthru Pro to a friend of mine...he hasn't talked to me ever since!

Well I download the flash reflash the computer and it sort of hangs at the end says error no communication with bus. I start vehicle it dies, start it again dies. Scan it and it needs vin programmed and the skim relearned needless to say I am upset. Call Snap-On they say it is not their problem its Chrysler problem and that I need call Chrysler yea sure. I then tell Snap-On they need to put a note on their web page stating it doesn't work with Dodge and we get into it. Tell him I bought the thing to flash dodges and whats the use of having to flash it when it will still need to be finished at dealer. Seriously considering sending it back to snap-on. I then find out this about the Pass Thru Pro 2

We are investigating an issue with 2003-2007 Dodge Ram vehicles equipped with Cummins engines. After programming this vehicle, the VIN is lost and the vehicle will not start. Until this problem is resolved, we suggest that technicians avoid reprogramming this vehicle with the techauthority.com website.

Flash Chryslers at you own risk!

Make sure your Mazda is not a medium speed can car. Mazda's website states these vehicles cannot be programmed with a J2534 device.

Mazda can be a pain and there are some that can't be done. I've done two now. GM Ford Kia and honda I've had no issues with other than not being able to do the honda keys. I do our local chrysler dealers non chrysler vehicle service so when I need one done I let them do it for me.

At this news flash I would think that SNAP-ON would be on the hook for reprogramming the vehicles affected by this short comming

That's like being mad at the TV manufacturer because your cable company doesn't carry the show you want. The device works fine. Chrysler, and many other manufacturers, have constant troubles with their flash programming software. Like every Tech, I sure wish it wasn't like this, but it is. It's not the fault of the device though.

My prediction is the tool is just going to become obsolete because you will no longer be able to add files , only be able to get a reimage of a completely new vehicle operating system at the dealer and the updates done to the system wirelessly wilth the vehicles parked in the dealer service lots.
