Engine Speed Below 200 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 at or below 200 RPM and the ECM detects engine restart parameters resulting from a driver action or system request, the ECM operates the TSS motor to first engage the pinion gear with the ring gear and then operate the motor to rotate the engine up to starting RPM. The ECM activates the fuel system and the engine systems to allow a restart.
