I'm assuming you have a diesel?
Service electronic throttle control is an error that is quite often displayed when a diesel Grand Cherokee fails to perform a DPF regeneration. It is basically saying it couldn't perform the regen, the dpf is full so its going into limp mode.
The dpf is a filter that collects diesel soot in the exhaust, when it starts to fill up the computer should see this with a sensor, and then trigger a regeneration, or a burn. It increases the exhaust temps up to 600 degrees and burns it off, like modern ovens do to self clean.
A lot of diesel grand cherokees are having this problem, it seems that many of the MY14 grand cherokees are failing to properly regen the dpf for some reason. Jeep released a software update in december that is supposed to fix the problem by changing the way the computer monitors the filter. Its looking hopeful so far. But there are other reasons a dpf can clog and regens not work correctly, the sensor could fail, or there can be a physical blockage in the filter.
There's a lot more reading here about the Australian Grand Cherokee diesels and the dpf issue.
Is DPF issue for 2014 CRD fixed now?
