. Actuate the brake pedal to the floor, hold for approximately two seconds and then release the pedal. Wait another two seconds and actuate the brake pedal again for a further two seconds. Repeat this action 20 to 30 times until clear,
bubble free brake fluid streams out.
. With the brake pedal actuated, close the bleeder screw. Build up fluid pressure by pumping the pedal and then open
the bleeder screw. Repeat this action three to five times.
If a filler unit is not used, observe the fluid level in the reservoir and top up if necessary.
. Repeat this procedure for the remaining three calipers. (1 Fig. 1) shows the bleeder screw of the rear left caliper.
. With the motor running check brake pedal travel. If excess- ive, check for leaks and repeat the bleed procedure.
. Fill the reservoir to the max level.
12.4.4
Hydraulic control modules are supplied pre-filled to enable
the brake system to be bled in the conventional way.
. Ensure that the vehicle is standing level. Switch the igni- tion off.
. Check that the fluid level in the reservoir is between the
min and max marks.
Connect the bleeder bottle tube to the relevant front cali- per (see 'note' on previous page) bleeder screw (1 Fig. 1) and open the screw.
. Actuate the brake pedal full stroke, wait a moment and
then release. Wait two to three seconds and then actuate
the brake pedal full stroke again. This allows the TMC to
be completely re
-filled with fluid.
. Repeat 20 to 30 times until the fluid in the bleeder tube is
clear and bubble free.

WARNING: BRAKE FLUID IS CORROSIVE. EXTREME CARE MUST BE TAKEN WHEN HANDLING. AVOID SKIN OR EYE
CONTACT. AVOID INGESTION. IF SKIN OR EYES ARE ACCIDENTALLY SPLASHED WITH BRAKE FLUID,
RINSE THE AFFECTED AREA IMMEDIATELY WITH PLENTY OF WATER AND SEEK MEDICAL ATTENTION.
IF BRAKE FLUID
IS INGESTED, SEEK MEDICAL ATTENTION IMMEDIATELY.
CAUTION:
Fluid must not be allowed to contact the vehicle paintwork. Remove any spilt fluid from the paintwork
by rinsing away with running water. Methylated spirit (denatured alcohol) must not be used to clean the
contaminated area.
Cleaning Solvents
CAUTION: Never use methylated spirit (denatured alcohol) for cleaning purposes. Use only a proprietary brake
cleaning fluid.
m: THROUGHOUT THE FOLLOWING MAINTENANCE / SERVICE OPERATIONS, ABSOLUTE CLEANLINESS
MUST BE OBSERVED TO PREVENT GRIT OR OTHER FOREIGN MATTER CONTAMINATING THE BRAKE
TION. TO CLEAN BRAKE SYSTEM COMPONENTS, WASH

12.5.2 Hoses
Fully release the unions (1 Fig. 1) securing each end of the
hose to the fluid pipes. Withdraw the pipe unions (1 Fig. 1) from the hose ends.
Plug the ends of the pipes (2 Fig. 1) to prevent the loss of
fluid and the ingress of dirt.
Remove the mounting bracket locknut (3 Fig. 1) and re- move the hose (4 Fig. 1).
Thoroughly clean the hose and examine for any signs of
wear or damage. Renew the hose if there is any doubt
about its condition. Thoroughly clean the bore of the hose
using compressed air.
. Remove all blanking plugs and fit the new hose to the cali- per / connector. Secure the hose to the mounting bracket.
. Before fully tightening the locknut, ensure that the hose is
neither kinked nor twisted.
. Bleed the brakes.
12.5.3 Pipes
. Fully release the pipe unions (1 Fig. 1).
. Withdraw the pipe (5 Fig. 1) from the vehicle. Plug the
pipes (2 Fig. 1) to prevent the loss of fluid or the ingress of dirt. Thoroughly clean and examine the pipe for signs of damage or deterioration. Renew the pipe if there is any
doubt about its condition.
Thoroughly clean the bore of the pipe using compressed

The front of the
PECUSprogrammable instrument panel features 6 analog gauges, 22 warning lamps /tell tales and
a Liquid Crystal Display (LCD), the rear of the panel accommodates two PCB mounted connectors, one 24-way
connector, one 48-way connector, one instrument panel identification label and 14 light bulbs arranged in groups of
seven on either side. Three power inputs and two ground inputs are provided for 'POWER UP' and 'POWER DOWN'
sequence, the three power inputs comprising battery, ignition and auxiliary. The instruments are protected by a
housing
/ lens assembly.
15.2.7 Gauges
The two major gauges are tachometer and speedometer, and the four minor gauges indicate battery condition, fuel
level, oil pressure and coolant temperature.
Each gauge is contained
in a sealed non-serviceable can and must be renewed as a complete unit in case of any
damage.
CAUTION: Extreme care should be exercised when renewing instrument pand components to avoid damago to the delicate indicator needles.

15.2.8 Odometer
With the ignition 'OFF' the odometer is permanently dis-
played but not illuminated. With the ignition 'ON' the odo- meter is displayed and also illuminated.
Trip information or driver information messages may be dis
-
played instead of the 'ODO'. By pressing the 'ODO' button
once or twice the trip and driver information messages can
be deleted and the
'ODO rdisplayed.
W. The odometer value is not stored within the LCD
module.

This provides information on the vehicle's speed, fuel usage
and distance traveled
all of which are calculated by a micro
processor.

15.2.10 Driver Information Messages
Two fault messages, FLUID - AIRBAG are displayed via the LCD in conjunction with relevant warning lamps.
If an
airbag fault exists or the brake fluid is low, a message will automatically be displayed on the LCD and the relevant
warning lights illuminated. Should both faults exist at the same time, each message is displayed alternatively for ap
- proximately 2 seconds.
Messages may becancelled
by pressing the 'ODO button which allowsthe LCD to return to its last displayed message.
The warning lamps will not be extinguished. If the fault is not repaired the message(s) and the warning lamp(s) will
be redisplayed when the ignition is switched on.
15.2.11 /llumination
Warning indicator lamp illumination is controlled by a microprocessor located inside the instrument panel.
The seven right
-hand warning indicators are primary warning lamps illuminating 'RED and the seven left-hand warn-
ing indicators are secondary warning lamps illuminating 'AMBER'
The eight lower lamps are
a mixture of status and warning lamps.
With the ignition
'OFF' the LCD is not illuminated.
With ignition
'ON' and side lights 'OFF' the LCD is illuminated at maximum brightness.
With the ignition on and side lights
'OFF' the LCD is dimmed as are the gauges.
The long
life type bulbs are enclosed by orange and brown coloured bulb holders which must never be interchanged.
Replacement bulbs must always be of the same colour.
CAUTIQN: Always dwonnect the battery ground lead before commencing with any instrument rsimwal procedure.
15.2.12 General Repair Notes
0 After lens removal do not rest instrument panel face down as this causes damage to the delicate gauge needles.
Avoid scratching the gauge faces and ensure cleanliness when handling the panel.
0 To minimize the risk of damage and contamination to the instrument panel, all repairs must be carried out in a non - static and dust -free environment. Avoid touching connector pins and pcb components to minimize
risk of static damage.
0 The instrument panel has two different types of bulb holders each of which must be located correctly when
changing the bulbs.
