Ancillary Systems
The an
ci
llary systems, driven by the engine, each have a
detailed Description and Operation along with Diagnostic
Procedures, and Removal and Installation instructions ; refer to the following sections of this manual:
Power Steeri

Ai
r Conditioning Compressor - Sectio
n 412-03
Engine
C
ooling Pump - Section 303-03
Generator
- Sectio
n 414-02
The drive belt, idler pulley and automatic tensioner are described in Section 303-05.
The engine starting system is described in Section 303-06.
En
gine Management and Emission Control System
Engine Control Modu
le (ECM)
Engine
management and exhaust emissions are controlled by the ECM, which has the
following main functions:
Fu
el injection
Idle
s
peed
Ignition Ev

aporative loss system
Engine
cooling fans Clim
ate control compressor clutch demand
The microprocessor within the ECM receiv es signals from various sensors and other modules and uses a pre-determined
program to compute engine management functions.
Adaptive functions are incorporated in the ECM to cater for co ntinuous adjustments to its computations to suit prevailing
conditions. Because the system also controls emissions to suit all modes, neither CO levels nor idle speed require service
attention or adjustment, except if an error should occur.
On Board Diagnostics are controlled by the ECM with the continuous monitoring of incoming signals and the subsequent
verification against what the module expects to 'see'. Should a si gnal be incorrect or missing, the ECM will substitute a fixed
value to provide the 'limp home mode' and alert the driver of the problem. Fixed values may be adopted for:
Transmission oil
temperature
Mechanica
l
guar
d position
Throttle blade angle Camshaft position

Inta
k
e air temperature
Diagnostic trouble codes (DTC), including OBD II codes, are stored in the ECM memo ry and can be read by an appropriate
retrieval tool.
Should either the ECM or TCM fa il, ensure that the control housing cooling fan is operating correctly. Failure of the cooling
fan MUST be rectified before renewing a control module and details of a fa n failure should accompany a returned control
module.

8. 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.
D
isconnect the belt from the
other pulleys and remove it.


9. Re
move the pulley from the water pump.
1. Remove the pulley securing screws.
2. Remove the pulley from the water pump.
10. Remove the belt tensione r assembly, from the Front
Accessory Drive. Refer to Operation 12.10.41.
11. Remove the idler pulley, from the Front Accessory Drive.
Refer to Operation 12.10.43.
12. Remove the crankshaft damper. Refer to Operation 12.21.09.
13. Carefully remove the engine covers, taking care not to
damage the plasti c fixings or the rubber inserts.
14. Disconnect the intake tube from the throttle body.
1. Remove the two bolts which secure the intake tube to the throttle body.
2. Disconnect the intake tube from the throttle body.

15
.
Reconnect the air flow meter multi-plug.
16. Refit the engine covers.
17. Refit the crankshaft damper. Refer to Operation 12.21.09.
18. Refit the idler pulley, to the Front Accessory Drive. Refer to
Operation 12.10.43.
19. Refit the belt tensioner assembly, to the Front Accessory
Drive. Refer to Operation 12.10.41.

20
.
Refit the pulley to the water pump.
1. Refit the pulley to the water pump.
2. Fit the pulley securing screws. Tighten as far as
possible; then to the correct torque after the belt has
been fitted.

21
.
Refit the drive belt to the generator and accessory drive.
Locat
e the belt around the pulleys, except the generator
pulley.
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, connect the drive belt to the generator pulley.
Release the tensioner sl owly and remove the
spanner.

22
.
Tighten the three screws wh ich secure the water pump
pulley, to 10-14 Nm.
23. Connect the top hose to the coolant outlet pipe.
1. Connect the top hose. Reposition the hose clip and tighten.
