Battery System (14.01)
Description
The 12 volt negative earth (‘-’ ve) battery is located under the RH side rear seat and is grounded to the vehicle body.
The battery positive (‘+’ ve) terminal is connected to a battery connect switch. The connect switch may be accessed by
raising the rear seat cushion.
Battery Connect Switch
When the battery connect switch is in an ‘open’ state it
isolates electrical power from all systems except the ‘keep
alive memory’ functions in the PCMs, TCU, radio,
navigation system and door modules.
This function isolates electri cal power from vehicle circuits
under all normal service conditions with the following
exceptions:
• Before any welding or other work which may induce high voltages into the electronic control modules
• Before disconnecting any of the control modules with ‘keep alive memory ’
• Before any major service task (e.g . engine removal)
• Before installing any accessory which involves modification of vehicle wiring
In the above four exceptions the battery earth (‘-’ ve) lead
should be disconnected.
When the battery earth (‘-’ ve) terminal is disconnected,
data held in keep alive memories will be lost. After connecting the battery, the radio preset stations and the
door window controllers will require to be reset (adaptive
learning data in the PCM module will require to be re-
learned by driving the vehicle for some miles in a range of
driving conditions),
driveability may be slightly
compromised until the vehicle systems have completed
their adaptive learning routines again.
Battery Disconnection and Alarm
Activation
The vehicle is installed with an alarm which will be activated
if the battery is disconnected. This alarm is driven by a back
up battery within the alarm sounder unit.
To prevent the alarm from so unding when the battery is
disconnected (for workshop procedures), disconnect the
battery within 10 seconds of switching off the ignition.
Always carry out the following procedures upon connection
of the battery.
• Reset the clock
• Reset the radio preset programmes.
• Reset the window maximum up and maximum down settings.

Charging Circuit
Electrical power generated at the alternator flows via two ‘T Pi ece’ connectors to the engine bay ‘Dirty Feed’ stud. It then
flows via the Battery Disconnect Switch (BDS) to the battery positive terminal. Both the alternator and the battery are
earthed via the vehicle body to complete the charging circuit.
The starter motor and the ‘jump start terminal’ ar e also fed directly from the charging circuit.
Go to page 18-X-XX for complete power dist ribution circuit diagram (Circuit Sheet 25).
+12 Volt Distribution
The +12 volt supply comes from the battery to the battery disc onnect switch (BDS). Assuming that this switch is not
activated, 12 volt power is then available from C0046-8 on the BDS to all of the clean feed battery studs.
The following clean feeds are then live:
• Boot fuse box clean feed
• Under bonnet fuse box clean feed
• CEM busbars 1, 2, 3 and 4 clean feeds
12V power to all systems and components is then controlled by the CEM and the under bonnet / boot fuse boxes.
