That is total BS. They CAN if they had the right tools, but CANNOT due to the fact they do not have the latest witech diagnostic equipment. You are being lied to by your dealer. Either they are ignorant or incompetent. Every dealer thought the new crap would be supported on the old diagnostic equipment. Jeep dropped this steaming pile of failure in dealers laps and there is this little thing that needs to be purchased in order to communicate with the new platforms. All a dealer can do without one is look at data at very high levels, not flash firmware/update software.
GCL and Wagoneer require this... it is brand new and only applies to the newest platforms. It cost a mint and NOBODY has them
Mopar Diagnostic Pod (MDP) works with Chrysler FCA wiTECH 2.0 subscription. It supports CAN-FD and Ethernet protocol. MDP will replace MicroPod2

See here to verify my words...
NOTE:
2021 WL Grand Cherokee L wiTECH 2.0 w/ MDP
Remind your dealer that FCA requires 3 of these tools per dealership or they can be removed from the brand. They do not require a dealership to have the adapter for the GCL/Wagoneer. Pretty FN smart huh?
"Reminder: FCA requires each dealership to have a minimum of three microPods for vehicle diagnostics, including at least one dedicated device for the Enhanced DRB III Emulator. The Ideal number of diagnostic solutions within a dealership is one for every technician."
See here...
My dealer flat out told me that they cannot afford more than one of these, and due to ordering it late, they was loaning one from an other dealer. Literally 5 technicians, all working on GCL/waggoneers sharing 1 loaner device, therefore nothing gets done, service delays, scheduling delays, etc...
Watch the movie Idiocracy. We have arrived.
