Starting System - INGENIUM I4 2.0L Diesel (G1895522): Overview

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

Depending on the transmission type and the market specification the engines are fitted with one of two types of starting system:

Vehicles without auto stop/start system (which vehicles are equipped only with manual transmission) have a starter motor incorporating a single solenoid.
Vehicles with auto stop/start system have a Tandem Solenoid Starter (TSS) motor (which vehicles are equipped with automatic transmission) or a starter motor (vehicles with manual transmission).

Both types of starting system are passive systems controlled by the Powertrain Control Module (PCM). The PCM initiates starting system operation when a valid smart key is in the vehicle and the engine stop/start switch is pressed.

The PCM controls operation of the starter motor using a starter relay in the Engine Junction Box 2 (EJB 2), on vehicles with and without stop/start.

On vehicles with auto stop/start system the PCM interacts with other vehicle systems to determine when stop/start operation is required. The auto stop/start warning indicator provides a visual indication of when the engine is stopped in a stop/start cycle. The stop/start function is automatically activated each time an ignition cycle occurs. However, if required the driver can deactivate the system using auto stop/start switch.

Vehicles with auto stop/start system incorporate a brake vacuum sensor to enable the PCM to monitor the pressure in the brake booster during stop/start operation.
