4. FAULT FINDING PROCEDURE (continued)
Wiring check:
Fault finding problems:
Disconnecting the connectors and/or manipulating the wiring may temporarily remove the cause of a fault.
Electrical measurements of the voltage, resistance and insulation are generally correct, especially if the fault is not
present when the analysis is made (stored fault).
Visual inspection:
Look for damage under the bonnet and in the passenger compartment.
Carefully check the fuses, insulation and wiring routing.
Look for signs of oxidation.
Tactile inspection:
While manipulating the wiring, use the diagnostic tool to note any change in fault status from stored to present.
Check that the connectors are correctly tightened, apply light pressure to the connectors, twist the wiring harness.
If there is a change in status, try to locate the source of the fault.
Inspection of each component:
Disconnect the connectors and check the appearance of the clips and tabs, as well as their crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the sockets.
Make sure no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Resistance check:
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to + 12 V or with another wire.
If a fault is detected, repair or replace the wiring harness.

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.

CRUISE CONTROL/SPEED LIMITER DEACTIVATION
NOTESSpecial notes:
Only perform the tests if the statuses do not correspond with the system programming
functions.
Note:
Cruise control can be activated when the vehicle speed exceeds 18 mph (30 km/h).
Status ET415 displays the various reasons for deactivation of the cruise control/speed limiter function, which are
due to driver demand or the exterior environment.
IMPORTANT
Clear the fault memory by running command RZ001 "Fault memory", to reset this status to "NONE".
NONEThis status is present on the diagnostic tool when:
The computer has been reinitialised.
The computer has been reprogrammed
STATUS 1Traction control request
If the vehicle is fitted with a traction control system, the cruise control function is
deactivated every time the ABS computer calls for traction control.
Status ET415 becomes STATUS 1 when driving with the cruise control active (ET042
Cruise control/Speed limiter: CRUISE CONTROL) and traction control is requested.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status ET415 becomes STATUS 1 with no traction control request (see 38C, Anti-lock
Braking System).
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
