Description an
d Operation
Ig

nition Switch
The k
ey-operated ignition switch is located on the right-hand side of the steering colu
mn and has four positions.
Position 'O'

OFF. The only position in which the key can be inserted or re moved. With the key removed, the steering lock engages. The
key can only be removed when the tran smission is in the Park position.
Position 'I'

AUXILIARY. Certain circuits , i.e. radio and windows, can be operat ed without switching on the ignition.
Position 'II'

IGNITION.
All circuits, except the star
ter motor, are activated. The key rema ins in this position when driving.
Position 'III'

START. The starter operates for as long as the key is held in this position, ag ainst spring pressure. If the engine fails to
start, the key must be returned to position 'I' befo re another start is attempted.
Lighting Switch

The li
ghting switch is on the left-h
and side of the steering column and controls the following functions.
Direction Indicators

The direction in
dicators:
Operate
when the ignition switch is in position II.
Are operat
ed by movi
ng the switch stalk up or down until it latches in position, to in
dicate a right or left turn
respectively.
Can be o p
erated while the switch stalk is held against
spring pressure before reaching the latch position.
Cancel
automatically upon completion of a turn, the
column switch returning to the center position.
An audible ticking and a flashing green warning lamp on the in strument cluster indicate that the direction indicators are

combin
ed with the outlet duct and consequently, there is no separate housin
g assembly fitted above the water pump, as used
on the normally aspirated engine. The illustration shows the outlet duct viewed from the engine.
Thermostat Housing

The plastic housing for the thermostat is fitted between th e two cylinder banks immediately above the coolant pump.
Controlling the coolant flow through the radiator, the thermostat starts to open at 80 ° to 84 °C and is fully open at 96 °C.
A duct in the cylinder block connects the thermostat housing outlet to the coolant pump inlet. The joint between the
thermostat housing and the cylinder block is via an in-groove seal.
An air bleed outlet vents an y air in the system into the expansion reservoir, durin
g normal operation. A removable cap (usin g
a hex key) allows air to vent from the system when filling from empty.
On supercharged engines, the thermostat housin g is combined with the coolant outlet duct.

Description and Operation


Manufacturer - NipponDenso
Type - RA1.4.
Weight - 3.75 kg (8.27 lb)
Output - 1.4 kW
Rated Time - 30 seconds
Rotation - Clockwise, viewed from pinion end
The starter is of the pre-engaged type; loca ted at the rear left-side of the engine.
When the starter is operated from the key-switch, the engagement lever moves the pinion into mesh with the engine ring
gear teeth, the electrical contacts within the solenoid complete the high power circuit and the starter motor operates to turn
the engine.
Starter Relay

The starter motor control relay is, relay nu mber 5, located inside the engine compartment enclosure (left side of vehicle
RHD and right side of vehicle on LHD).

The il
lustration above is a simplified expl
anation of how the starting system operates in conjunction with the Body Processor
Module (BPM) and the Engine Control Module (ECM).

The BPM
'CRANK SELECTED' terminal is ta
ken to 0V by the ignition switch.
The BPM
'O/P ENGINE CRANK' terminal pr
ovides a path to ground for the starte r relay coil, via Fuse 5 (10A) located
in the engine compartment front fusebo x. This path to ground also indicates to the ECM 'I/P ENGINE CRANK'
terminal, by taking it to 0V, that the engine has been requested to crank.
Wi
th the starter relay contacts closed,
power via Fuse 3 (25A) in the engine compartment rear fusebox, is supplied
to the pull-in winding of the starter solenoid.
The s
olenoid main contacts close and are held
closed by the solenoid hold-in winding.
Battery power is supplied
to
the starter motor through the solenoid main contacts, direct from the battery and the
High Power Protection Module.

Installation


7. Remove the output shaft flange.
1. Using a suitable tool, reli eve the 'staked' portion from
the output shaft keyway.
2. Remove and discard the fl ange nut using a suitable
socket and resisting rotation with special tool 205 -
053.
Check the flange se al diameter for damage and renew if
necessary.

8. Remove and discard the oil seal.
Use a proprietary seal removing tool, taking care NOT to
damage either the shaft or the housing.
1. Installation is the re verse of the removal procedure noting the
following:

2. Fit the oil seal.
1. Lubricate the housing seal bore.
2. Lubricate the outside diameter of the seal.
3. Using seal replacer 307-378 drive the seal squarely into position.
3. Refit the drive flange.
1. Use a new nut. Tighten the flange nut to

Automatic Transmission/Transaxle External Controls - 4.0L NA V8 -
AJ27/3.2L NA V8 - AJ26 - Brake Shift Interlock Ac tuator Manual Override
General Procedures



1. To override the gearshift interlock:
1. Unscrew the release catch blanking plug.
2. Insert the ignition key into the aperture, depress the release catch and simultan eously move the gear
selector lever from the Park position. The lever will
only move approximately 25 mm with the key
inserted.
3. Remove the ignition key and replace the blanking plug.

Selector lever:
Gear selector positions are:
P Transmission mechanically locked, starting available * R Reverse gear N Neutral gear, no power to the rear wheels (starting available) D Drive gear, all 5 forward gears available (see Performance Mode Pushbutton) 4 Upshift to 4th gear only 3 Upshift to 3rd gear only 2 Upshift to 2nd gear only
Gearshift Interlock Manual Override*
The interlock system which locks the sele ctor in P and prevents the ignition key from being removed except when P is
selected, may be manually overridden in the event of an emergency.
1. 1. With the parking brake applied
2. 2. Remove the access blank using a suitable Torx bit
3. 3. Insert a small screwdriver into the vacated hole
4. 4. Push the screwdriver downwards, gently, and hold whilst simultaneously moving the selector from P towards R ,
but do not engage R until the tool has been removed
5. 5. An audible warning may be heard when operation 4 is carried out
6. 6. With the selector in N and the access bl ank replaced, the vehicle may be started
Range Selection
The selector lever transmits operator demand to the transmission and TCM by means of a cable and Dual-Linear
Switch (DLS).
The lever operates the transmission assemb ly selector shaft, only for P R N D , by means of a cable. Movement of the
lever across the gate to 4, 3 and 2 positions disengages th e cable from the selector lever and engages the DLS which
controls gear selection electronically.
Gear selector module:
Provides illumination of the decal relevant to the gear sele cted. This information is provided by CAN from the TCM. Illuminates the security system Active LED on the gear selector surround, in response to an output from the BPM.
