CHARGING AND STARTING – Td4
DESCRIPTION
Starting
The starting system on the vehicle comprises a 12 volt starter motor which drives the engine 
to start the combustion process. The starter converts electrical energy into mechanical 
power. The vehicle electrical system must be capable of supplying sufficient power to enable 
the engine to be cranked.
Charging
The charging system comprises a battery and an alternator. The battery must be of a 
sufficient...

Starting
Main Relay
The earth path for the main relay coil (C0576) is controlled by the Engine Control Module 
(ECM) (C0603) on a WK wire. The energised main relay provides a feed to fuse 1 which is 
also located in the engine compartment fuse box. Fuse 1 (C0576) provides a feed to the 
glow plug relay (C0215) on an RW wire.
For a detailed description of main relay operation, refer to the  Engine Management 
Systems – EDC  section of the System Description...

Starter Relay
Fuse 5 of the passenger compartment fuse box (C0581) provides an ignition switch crank 
feed to the immobilisation ECU (C0059) on a WR wire. If the vehicle has been successfully 
re-mobilised, the immobilisation ECU (C0059) provides a feed to the starter relay coil 
(C0576) on an RW wire. The starter relay is located in the engine compartment fuse box, 
and is earthed (C0576) on a B wire. A battery feed from fusible link 7 is now able to flow...

Charging
Alternator
The battery (C0192) provides a permanent feed to the alternator (C0183) via the starter 
motor (C0631) on an R then N wire. Fuse 19 of the passenger compartment fuse box 
(C0581) provides an ignition feed to the alternator (C0226) on a W then GN wire. 
When the engine is turned over, the alternator (C0226) supplies the ECM (C0606) a Pulse 
Width Modulated (PWM) signal on a U wire. The ECM uses this PWM signal to calculate the 
electrical...

Systems – MEMS  section of the System Description and Operation Workshop manual.
Inertia Switch
Fuse 10 of the engine compartment fuse box (C0575) provides a constant battery feed to 
the inertia switch (C0123) on a G wire. The inertia switch is a normally closed switch. If the 
inertia switch hasnt been tripped, current flows across the switch (C0123) to the fuel pump...

Central Control Unit (CCU)
The CCU (C0428) receives a feed from the inertia switch (C0123) via the engine 
compartment fuse box (C0576) on a UG wire. If this feed is removed due to the inertia switch 
being tripped, the CCU will unlock all of the doors. For more details of the Central Door 
Locking (CDL) system, refer to the  Anti-theft Alarm and Central Door Locking (CDL)  
section of this manual.
