Today I was working on a 09 Ram 5500 6.7 (Vin not available) anyway, came in with "See Dealer, DPF 90% full" on the info center. Did mobile desoot, message gone, but I found a TSB regarding a flash which adds a stationary regen to the software. Now my question is this. When the scanner sets up its menus, for example "System tests", is that hard programmed to the scanner, or does the scanner poll the vehicle for supported tests and displays them. In other words, if I did the flash, would I then have an option for a stationary regen under system tests? Since the 3500 has this stationary regen already, if I IDed it as a 3500, would the option be there then, and are the memory/software addresses the software talks to the same on both trucks?

The software does not poll the car to find out what tests are available. If a stationary regen became available for that truck, Snap-on would have to add it to their coverage for it to be available."You don't build a reputation on what you're going to do"

If you id the truck as a 3500 the stationary regen would be in the functional test because it"s there for the 2500/3500 6.7"s. If you tried to perform the test you will get an error message because the 5500 ram did not support that test. after performing the tsb witch is a reflash addding the stationary regen and a few urea system tests it will work, but you would have to id the truck as a 2500/3500 untill it gets added to the software for the 5500 trucks.Comment

Here is the explanation I received when I asked about this:
For 6.7 diesel engine we match the ECU ID (ECUcalibration/software) to a set of PIDs and tests that are supported for that ID. When a newer version of software is flashed the ECU gets a new ID and we then pair our data, PIDs and tests, to this new version. We have the stationary desoot test on the ECU IDs that support it, so yes, if he flashes the ECU with the latest software that Chrysler has for this engine the stationary desoot test should be displayed as a selection on our scanner. He needs to have a fairly current software release (about 11.4).Comment
