WARNING
This fault only appears in Vdiag 48.
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– a road test,
– an actuator command AC002 EGR solenoid valve.
Special notes:
The EGR and turbocharging functions are inhibited.
The level 1 warning light comes on.
Use bornier Ele. 1681 for all operations on the injection computer connectors.
Check the EGR valve connections.
Check the injection computer connections.
Repair if necessary.
Clear any stored faults.
Run command RZ002 EGR Adaptives to reinitialise the valve operating values.
Switch off the ignition and wait for the engine immobiliser warning light to start flashing.
Switch the ignition on again and check the system faults.
If the fault is still present:
– remove the EGR valve, and then reconnect it,
– check that the movement of the valve is not being blocked by a particle,
– check that the valve is not jammed or stuck in one position,
– run command AC002 EGR solenoid valve,
– check the movement of the solenoid valve,
– check that the solenoid valve is completely closed,
– if there is no movement, or if the valve is seized and cannot be repaired, replace the EGR solenoid valve.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.

ET415
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 shows various factors that cause deactivation of the cruise control/speed limiter function, due to a
driver request or the external environment (e.g. STATUS 1).
IMPORTANT
Clear the fault memory by running command RZ001 Fault memory to reset this status to NONE.
WITHOUTThis 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.

(CONTINUED 4)
STATUS 8Automatic gearbox 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 the present or stored faults (see 23A, Automatic transmission,
Interpretation of faults).
Clear the automatic transmission computer memory by running command RZ001 Fault
memory or RZ007 Fault memory.
Reinitialise ET415 of the injection computer by running command RZ001 Fault
memory or RZ007 Fault memory.
If STATUS 8 remains, contact 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 any present or stored faults (see 38C, Anti-lock braking system,
interpretation of faults).
Reinitialise ET415 of the injection computer by running command RZ001 Fault
memory or RZ007 Fault memory.
If STATUS 9 remains, 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.
