Engine Speed Between 200 and 350 RPM

WARNING: This page is about a different car, the 2015 Jaguar XF, 2014 Jaguar XF, and 2013 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.

When an ECO stop is initiated, the engine speed is between 200 and 350 RPM and the ECM detects engine restart parameters resulting from a driver action or system request, the ECM operates the TSS motor to first accelerate the pinion gear up to the ring gear speed and then to engage the pinion gear with the ring gear to rotate the engine up to starting RPM. The ECM activates the fuel system and the engine systems to allow a restart.
