The original DRB III was THE Chrysler (and Dodge, Jeep, Plymouth, etc.) dealership diagnostic tool for something like a decade, until 2007 when it was replaced by newer technology. So the DRB III Enhanced Emulator being discussed here can do a LOT of Chrysler brand 2007 and earlier vehicle diagnostics / settings, but NOT other brand vehicles. It includes some generic OBD function which is all about emissions, but in that mode may do no more than the $20 generic OBD units. DRB III is all about servicing Chrysler vehicles from a while ago.

Special historical aside: When the original DRB III was retired in 2007 the new dealership diagnostic tool had to include a DRB III Emulator for older vehicles. Like my 2007 minivan which depends on DRB III software for many specialized tasks. What was NOT updated at the time was software / hardware to deal with the Chrysler / Mercedes "combination" vehicles like Crossfire and Sprinter van. Those required an additional Multiplexer "cable" (with a sizable box on it) to communicate between the CAN in Crossfire (and Sprinter) and the DRB III, along with special software cards which plugged into the DRB III. With the Chrysler - Daimler 2007 divorce those features were not included in the new dealership Emulator system, so the original DRB III and Multiplexer and Crossfire software card were still required to service Crossfire. Only something like half the USA Chrysler dealerships were ever authorized to sell Crossfire, so a lot of dealerships never bought the special Crossfire tools (like Multiplexer and Crossfire software card). Then with the DRB III going obsolete for other Chrysler vehicles, the hardware was forgotten, lost, walked off, etc. Not until 2017 was an Enhanced DRB III Emulator updated into the dealership wiTECH system - which finally included Crossfire (and Sprinter) capability!

With the various ownership changes of Chrysler the Enhanced Emulator software got out, along with the microPOD II being cloned in China. Hence we can make these systems to keep Crossfire alive and functioning. The DRB III never had anything like the capabilities of native Mercedes dealership systems, but did need to take care of main vehicle features. Since the Crossfire TPMS has nothing in common with Mercedes, it was a Chrysler system crammed into SLK architecture, the DRB III Emulator is the only access for that. Same for a few other things, like the convertible top, later changes to the more elaborate airbag system in 2007 Crossfire, perhaps a few other items.

When TPMS sensors must be triggered for the TPMS Relearn process (initiated only via DRB III) a fancy TPMS tool is not required. While the original factory TPMS sensors needed a magnet to trigger, that method went away for more modern sensors. The universal trigger is now a low frequency radio signal which can be sent from a pretty cheap single purpose device. Reading the code transmitted by the sensor (which includes the sensor ID) takes a more elaborate TPMS tool, but it could be an outdated tool version no longer up to date for new cars.

Congratulations and thanks for the people in this thread sharing tools to keep Crossfires doing their things!
