2. Role of components, operating strategy
Engine immobiliser
The Verlog 4 type immobiliser function is managed by the UCH computer and the engine management computer.
Before any starting request, the engine management computer is protected.
When a starting request is made, the injection computer and the UCH exchange authentication data via the multiplex
network; this determines whether the engine start is authorised.
After more than 5 consecutive failed authentication attempts, the engine management computer goes into protection
(antiscanning) mode and no longer tries to authenticate the UCH computer. It only exits this mode when the
following sequence of operations occurs:
– the ignition is left on for at least 20 seconds,
– the message is switched off,
– the injection computer self-supply cuts out when it should (the time varies according to engine temperature).
After this, only one authentication attempt is allowed. If this fails again, repeat the sequence of operations described
above.
If the engine management computer still fails to unlock, contact the Techline.
Impact detected
If an impact has been stored by the injection computer, switch off the ignition for 10 seconds, then switch it back on
so that the engine can be started. Clear the faults.
Torque management
The torque structure is the system for managing engine torque. It is necessary for some functions such as the
electronic stability program (ESP) and the automatic gearbox.
Each inter-system (ESP and automatic gearbox) sends a request for torque via the multiplex network to the injection
computer. It arbitrates between the inter-system torque requests and the driver's request (pedal or cruise control/
speed limiter). The result of the arbitration gives the torque setpoint. The torque structure uses the torque setpoint to
calculate the throttle position setpoint, the advance and, if there is turbocharging, the turbocharger valve setpoint
(wastegate) for engines fitted with a turbocharger. WARNING
Disconnect the injection computer when carrying out any welding work on the vehicle.

minimum stop and the camshaft angle measurement is forced to 0.
Tooth signal fault.
Tooth/camshaft signal consistency diagnostic.
●Status 2
This defect mode covers all faults affecting the dephaser (pulley and solenoid valve). The dephaser is set to
the minimum stop.
Electrical fault finding on the solenoid valve.
Dephaser position fault finding procedure.
7. Operational safety
Warning lights illumination
The S3000 Injection system manages the illumination of three warning lights and the display of warning messages
according to the severity of the faults detected, with the aim of informing the customer and guiding fault finding.
The injection computer manages the illumination of warning lights and warning messages displayed on the instrument
panel. These warning lights illuminate during the starting phase and in the event of an injection fault or engine
overheating.
The warning light illumination signals reach the instrument panel via the multiplex network.
Warning light illumination principle
During the starting phase (START button pressed) the OBD (On Board Diagnostic) warning light comes on for
approximately 3 seconds then goes out.
If there is an injection fault (level 1), the message CHECK INJECTION is lit, followed by the SERVICE warning light.
It indicates a reduced level of operation and a limited safety level.
The driver should carry out repairs as soon as possible.
Components involved:
– motorised throttle valve,
– accelerator pedal potentiometer,
– inlet manifold pressure sensor,
– computer,
– actuator feed,
– computer feed.
If there is a serious injection fault (level 2), the red engine symbol and the word STOP (display with information
display only), appears with the message ENGINE OVERHEATING followed by the STOP warning light and a
buzzer. If this happens, the vehicle must be stopped immediately.
When a fault causing excessive pollution in the exhaust gases is detected, the orange OBD warning light engine
symbol is lit:
–flashing in the event of a fault which might cause destruction of the catalytic converter (destructive misfires). If this
happens, the vehicle must be stopped immediately.
–constantly in the case of non-compliance with the anti-pollution standards (polluting misfires, catalytic converter
fault, oxygen sensor faults, inconsistency between the oxygen sensors and canister fault).

STOREDCLUTCH PEDAL CIRCUIT
1.DEF: Component in bad condition
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is present with the engine running and following a check on the number of
times the clutch pedal is depressed in relation to the number of gear changes
calculated by the computer.
Special note:
– engine speed surges when changing gear,
– the acquisition is made if the vehicle is not fitted with an automatic transmission,
– in the event of a fault, before replacing any component, check using the diagnostic
tool that the clutch contact is operational and that the recommended clutch pedal
clearance is still valid.
– In the event of an open circuit or short circuit to + 12 V, the clutch pedal is
depressed all the time which makes it impossible to select a cruising speed in cruise
control mode. The speed limiter remains operational in defect mode (inaccurate
speed restriction),
–If short circuit to earth, status ET405 Clutch pedal switch remains INACTIVE.
Check the cleanliness, condition and fitting of the clutch pedal switch.
Repair if necessary.
If the fault is still present, disconnect the switch. Check that when the clutch pedal is depressed, the switch is
closed, and when the clutch pedal is released, the switch is open.
Replace the switch if necessary.
If the fault is still present, manipulate the harness to see if the status changes.
Look for any damage to the wiring harness, and check the condition and connection of the connectors of the
injection computer and clutch pedal switch.
Repair if necessary.
If the fault is still present, check the earth on track 2 of the switch.
If the earth is not present on track 2, check for insulation, continuity and the absence of interference
resistance on the following connection:

ET415
(CONTINUED 3)
STATUS 7Inconsistency between the request and the vehicle speed
Status ET415 becomes STATUS 7 if the computer detects too great a difference
between the speed requested by the driver and the vehicle speed.
STATUS 7 may occur when driving with the cruise control active (ET042 Cruise
control/speed limiter: CRUISE CONTROL) and when there is significant difference.
This inconsistency deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status ET415 changes to STATUS 7 where there is no significant difference in the
levels, contact the Techline.
STATUS 8Automatic transmission in defect mode.
Status ET415 becomes STATUS 8, when driving with cruise control active (ET042:
Cruise control/speed limiter: CRUISE CONTROL) and if the automatic transmission
is in defect mode.
This signal is conveyed on the multiplex line and deactivates the cruise control.
Carry out a multiplex network test, then run fault finding on the automatic transmission
computer.
Deal with any present or stored faults (see 23A, Automatic transmission,
interpretation of faults).
Clear the automatic transmission computer memory by running command RZ001 Fault
memory.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status 8 continues, contact the Techline.
STATUS 9Vehicle speed monitoring
Status ET415 changes to STATUS 9 if the vehicle speed received by the computer is
invalid or absent.
This signal is conveyed on the multiplex line and deactivates the cruise control.
Carry out a multiplex network test, then run fault finding on the ABS computer.
Deal with present or stored faults (see 38C, Anti-lock braking system, Interpretation
of faults).
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If STATUS 9 is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
