Shiftlights (8):
Shiftlight thresholds are fully configurable using the “Toolset” software, see chapter G-
Softwares
The LEDs light up in all gear ratios. By default, t he setup is the following one:

LEDs Alarm (2):
On the left side, 1 LED lights up when an engine al arm rises up
On the right side, 1 LED lights up when a Gearbox a larm rises up

These LEDs are associated with the message displaye d in the area “Default” and with the
letter recorded in the area “events”

B.6.3.4 Alarms displayed on the dashboard

Alarms are generated by the ICD depending on engine / gearbox sensors values sent by
the ECU for display.
The alarm/default message disappears only when the problem is solved. Even if the
problem is solved, till the power supply is ON :
- The top left and/or right LEds alarms remain ON
- The letter in the area “event” is displayed

We distinguish 2 categories of alarms : A and B
B.6.3.4.1 M
AIN ALARMS (CATEGORY A)

The following alarms are displayed to the driver, m eaning that he must immediately
stop the car and cut the engine.
o Water T max
o Oil P min
o Vbatt min

See List on next page with the corresponding thresh olds.

A message is displayed on the full screen on the da shboard + in the Area ‘Default” to
force the driver to stop
In addition with the message displayed, all the fol lowing LEDs become RED:
- 3 on the Right column (above gearbox diagnostic L ED)
- 3 on the Left column (above engine diagnostic LED )
+ 1 engine alarm LED in RED

B.6.3.4.2 SECONDARY ALARMS (CATEGORY B)
All non Cat A alarms are classified in the category B. They are clearly displayed to the
driver, but he is still able to drive normally (the dashboard information remains normally
readable).
A message is displayed in the Area “Default”
In addition with the message displayed, the corresp onding alarm LED becomes ORANGE:
- 1 Right HS column (gearbox diagnostic)
- 1 Left HS column (engine diagnostic)

If 1 or more alarms are present, the messages are s crolling in the “default” area

B.6.4 BASIC PROCEDURES
B.6.4.1 Power-up

Press the “ON” button of the facia switch panel
(See B.6.1) to power supply the vehicle
The “COSWORTH” home page appears when the dashboard display first comes on, and
then moves to the first driver page (RACE Page)
B.6.4.2 Starting

Once the vehicle’s electrics are on, flick the vehi cle's “IGNITION” switch to the up (ON)
position.
Check that no gear is engaged (the letter “N” is di splayed on one of the display screen’s
driver pages).
Press on the “START” button without touching the Gas Pedal


The vehicle will only start if the following elect ronic equipments are connected
and are working properly:
- ECU
- CBNT
- Master relay
It is possible to start without plugging the dashbo ard
NOTE :
For the first engine start after engine refitting, it’s necessary to bleed the fuel
rail. To make it properly, please follow carefully the procedure indicated in chapter C-
Engine

B.6.4.3 Turning off the engine

Flick the “IGNITION” switch to the down (OFF) posit ion

NOTE : The vehicle’s electrics remain switched on
Except in the event of an emergency stop, it’s stri ctly not advised to turn off the
engine using the power supply switch (OFF button).
It is also recommended to wait 30seconds between sw itching off the engine and
switching off the power supply.
Respecting these two recommendations will guarantee optimum operation of the power
steering.
B.6.4.4 Switching off the power supply

Press the “OFF” button of the facia switch panel an d hold there for at least half a second.
The dashboard display is switched off.
NOTE: Switching off the power supply also switches off th e engine.

B.6.4.5 Changing gears

2 modes are possible and are completely independent . It’s possible to make randomly
upshift and downshift manually (using the lever) or in semi-auto using paddle shift kit.

Please refer to Chapter D-Transmission/shifting for a complete description of the shifting
modes.
B.6.4.6 Pit limiter

The purpose of this function is to limit the vehicl e's speed to 60kph
. It is enabled and
disabled by the driver.
Principle:
By pressing the button “PIT” of the steering wheel, Engine revs are thus limited (by the
ECU) to those corresponding to a speed of 60kph and the message “PIT LIMITER” is
displayed on the dashboard in the RPM Area :

C-24

If the pit limiter is activated while the current s peed is > 60kph, all the Shiftlights flashes
together till the vehicle reach 60kph (at this part icular moment, all shiftlights remains ON
but without flashing)


NOTE
: The speed limiter does not control the brakes. Cons equently, the vehicle speed
will only slow rapidly to 60kph if the driver appli es the brakes.

To disable the pit limiter mode, the driver has to press the button “PIT” of the steering
wheel : the message “ Pit Limiter” disappears on the display.

Specific conditions:
The driver may only enable and disable the speed li miter when the vehicle is in on a
forward gear (1 to 4)
B.6.4.7 Controlling the rain light

The rain light is switched on by flicking the “rain ” switch to the up position (ON).

The central rear rain light is ON continuously whe n enabled.

However, it is lightning automatically with flashin g phases (flashes at 0.5Hz) in the
following specific situations: - When the Pit limiter is enabled
- For a period of 20 seconds after the engine stall s
- When Reverse Gear ratio is shifted
