ET415CRUISE CONTROL/SPEED LIMITER DEACTIVATION
STATUS DEFINITIONThis status varies according to engine specifications.
Note:
Cruise control can be activated when the vehicle speed exceeds 18 mph (30 km/h).
Status ET415 shows various reasons for 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".
Conformity check: Engine stopped, ignition on or engine running.
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).

STATUS 6Gear lever in neutral (manual gearbox) or the neutral position (automatic gearbox)
Status ET415 becomes STATUS 6 when driving with cruise control active (ET042
Cruise control / speed limiter: CRUISE CONTROL) and:
–if the driver puts the gear lever in neutral position on a manual gearbox without
declutching or,
–if the gear lever is put in neutral on an automatic transmission.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status ET415 becomes STATUS 6 without shifting the gear lever into neutral on a
manual gearbox without declutching, or into the neutral position on an automatic
transmission, run fault finding on the ABS computer and check the configuration of the
tyre size stored in the computer. If the configuration is correct, contact the Techline.
STATUS 7Lack of correlation 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.
This could occur when driving with cruise control active (ET042 Cruise control/ speed
limiter: CRUISE CONTROL) and when there is a significant difference.
This inconsistency deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status ET415 becomes STATUS 7 on flat terrain, contact the Techline.

STATUS 8Automatic gearbox in defect mode.
Status ET415 becomes STATUS 8 when driving with the cruise control active (ET042
Cruise control/speed limiter: CRUISE CONTROL) and the automatic gearbox is in
defect mode.
This signal is conveyed on the multiplex line and deactivates the cruise control.
Carry out a multiplex network test (see 88B, Multiplexing), then run fault finding on the
automatic gearbox computer.
Deal with any present or stored faults (see 23A, Automatic gearbox).
Clear the fault memory of the automatic gearbox computer by applying command RZ001
Fault memory.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If the specification STATUS 8 is still present, contact Techline.
STATUS 9Vehicle speed monitoring
Status ET415 becomes 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.
Test the multiplex network (see 88B, Multiplexing), then run fault finding on the ABS
computer.
Deal with any present or stored faults (see 38C, Anti-lock braking system).
Reinitialise status ET415 on the injection computer by running command RZ001
