STATUS 5
Cruise control or speed limiter monitoring
This status appears when the vehicle brakes or decelerates sharply without the
injection computer receiving a signal that the brake pedal switch has been pressed.
If status ET415 is STATUS 5, consult the interpretation of statuses:
– ET042 Cruise control/speed limiter
– ET703 Cruise control/speed limiter buttons
– ET704 Brake switch No. 1
– ET705 Brake switch No. 2
to test the cruise control/speed limiter system components and find the defective
component.
Also, check the operation of the accelerator pedal, and use the diagnostic tool to
check the presence of a fault connected with this component. Deal with them if
necessary.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If status ET415 changes to STATUS 5, deal with faults present or stored in the
injection computer.
If the fault is still present, contact the Techline.
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, test the ABS computer and check the configuration of the tyre size
stored in the computer.
If the configuration is correct, contact the Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

STATUS 7
Inconsistency between the request and the vehicle speed
Status ET415 changes to 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 changes to STATUS 7 when on flat or even terrain, 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).
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 is still present, contact the Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

STATUS 9
Vehicle 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.
Carry out a multiplex network test, then run fault finding on the ABS computer.
Deal with any present or stored faults (see 38C, ABS, 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.
STATUS 10Monitoring by the injection computer.
Status ET415 becomes STATUS 10 when driving with cruise control active (ET042
Cruise control/speed limiter: CRUISE CONTROL) if the injection computer detects
a fault anywhere in the engine management system, or an engine speed that is too
high or too low.
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 injection computer.
Deal with any present or stored faults (see 13B, Diesel injection, interpretation of
faults).
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If STATUS 10 is still present, contact the Techline.
