Start Sequence

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

At the beginning of a start sequence, the FFBHCM energizes the FFBH coolant pump then operates the following in a preset sequence to start the FFBH:

Once combustion has stabilized the FFBHCM switches off the glow plug. If the FFBH fails to ignite the FFBHCM repeats the start sequence.
