Starting System - V6 S/C 3.0L Petrol (G1895524): 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.

The starting system is fitted with a starter motor incorporating a single solenoid, in a system with or without auto stop/start system.

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 an auto stop/start system the PCM interacts with other vehicle systems to determine when stop/start operation is required. An 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 an auto stop/start switch.

Vehicles with an 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.
