Information and Message Center - Information and Message Center
Description and Operation

The Driver's Information / Message Center has a liquid crystal display and is located at the lower area of the Major
Instrument Cluster.
The message center displays messages in text form for the driver, including odometer readings an d trip computer data. It
can also provide information normally covered by conventional wa rning lamps or typically indicate that a feature such as the
Automatic Stability Control is operating.
Located above the message center are two lamps, red for warning and amber for caution. When a message is displayed, the
appropriate lamp will illuminate to attract the driver's attention and to signify the importance of the message. The lamps
also illuminate simultaneously for some warnings and for some non-text warnin gs - refer to the Drivers Handbook for
variations in local markets.
Trip Computer

Pressing the trip switch on the left stalk of the steering colu mn switch assembly activates the trip computer which displays
trip data on the message center. Warning and Information messages have priority ov er trip data; if a driver information
message is displayed prior to activation of the trip computer , the trip data will appear for 10 seconds only, before being

Generator and Regulator - Generator
Description and Operation
Generator - General View
Features
Manufacturer - Denso Type - L3B-HE Drive Ratio - 3.04:1 Output - 120 Amps at 5000 rpm (generator speed) at 25° C
The generator is fitted at the front right hand side of the engine, to a sepa rate mounting bracket, which in turn is bolted to
the cylinder block. Two bolts secure th e generator to the mounting bracket; one is reached from above and one from below
the vehicle.
The voltage regulator is integral with th e generator body. Battery charging capabi lity has been optimised for charging a
battery which is located remotely, in the luggage compartment. The design of the generator and regulator has been finely
matched, to generate charging current with very low ripple. This provides the best electrical refinement to the system.
The generator is driven by a single, multi-ribbed belt which also drives all other front-e nd accessories; except for the
supercharger (where fitted).
No special service tools are required to remove the generator from the vehicle.

Removal and Installation
Removal

1. Disconnect the batt ery ground cable.
Remove the battery cover.
2. Remove the air cleaner assembly (including fit body paintwork
protection sheets to the adja cent working area); refer to
operation 19.10.05.
3. Remove the twin fan and moto r assembly from behind the
radiator; refer to operation 26.25.12.
4. Check that the belt wear indicator is within the limit marks.

5. Remove the drive belt from the generator and accessory
drive,
1. Use a spanner e.g. Churchill JD-230 or Snap On XDHM 1415, on the centre bo lt of the belt tensioner
idler pulley, to turn the adju ster assembly to the left
against spring tension.
2. Whilst holding the tensioner against spring tension, remove the drive belt from the generator pulley.
Release the tensioner sl owly and remove the
spanner.
Disconnect the belt from the ot her pulleys, as necessary,
to move it clear of the generator.
6. Raise the vehicle on a ramp; refer to Section 100-02

7. Remove the air intake ducting fr om the generator. The ducting
comprises two sections; the upper section is retained by two
screws to the sump body assembly and the lower (horizontal)
section is retained by one screw.
8. Disconnect the generator harness.
1. Disconnect the harness multi-plug.
2. Remove the protective boot from the positive
terminal, remove the termin al nut and disconnect the
cable from the terminal. Where fitted, disconnect the

suppression module positive cable from the positive
terminal.
3. Where fitted, remove the nut which secures the
suppression module negati ve cable and disconnect
the cable from the generator. Reposition the
suppression module harness clear of the generator.

9. Remove the lower mounting bolt and reposition the harness
mounting bracket.

10. Remove the upper securing bolt and withdraw the generator
from the mounting bracket.

11. Carefully, manoeuvre the ge nerator forward towards the
radiator.
12. Change the position of the ge nerator and remove it upwards
between the engine and the radiator.

Installation


13. Move the spacing bush rearward s slightly in the generator
mounting bracket, to ease fitting the new generator.
1. Position a suitable length bolt through the bush, fit a
tubular spacer or socket spanner, fit a nut and
tighten the assembly to move the bush slightly.
Remove the nut, bolt and spacer.

1. Fit the generator to the engine.
1. From above, position th e generator and fit the upper
mounting bolt and nut, but do not fully tighten.

2. Fit the generator lower mounting.
1. From below, reposition an d align the harness clip to
the generator lower mounting.
2. Fit the lower mounting bolt and nut, tighten to 38-48
Nm.
3. Connect the harness.
1. Reposition the suppres sion module harness and
connect the negative cable to the generator negative
terminal. Fit and tighten the terminal nut.

2. Secure the suppression module positive cable and
main positive cable to the generator positive
terminal.
3. Fit the boot to the terminal.
4. Reconnect the generator harness multi-plug.

4. Refit the air intake ducting to the generator. The upper section
is retained by two screws to the sump body assembly and the
lower (horizontal) section is retained by one screw.
5. Lower the vehicle on the ramp ; refer to Section 100-02.
6. Fully tighten the generator upper mounting bolt, to 18-24 Nm.

7. Refit the drive belt to the generator.
1. Pass the drive belt around the idler pulley.
2. Using spanner )Churchill JD-230 or Snap On XDHM 1415) on the centre bolt of the belt tensioner idler
pulley, rotate the adjuster against spring tension.
3. Whilst holding the tensioner against spring tension, pass the drive belt over the generator pulley and
check that it is correctly located on the other pulleys.
Release the tensioner slowly and remove the
spanner. Check the alignment of the belt.
8. Refit the fan and motor assembly ; refer to Operation 26.25.12.

9. Refit the air cleaner assembly; refer to Operation 19.10.05.
