of the black 32-track connector A of the injection computer.
Check and ensure that earth is on track 2 of the clutch switch connector.
Repair if necessary.
– Remove the clutch switch and test its operation:
– Replace the switch if necessary.

ET415
CONTINUED 1
STATUS 2
Brake pedal depressed
The cruise control function is deactivated when the brake pedal is depressed.
Status ET415 becomes STATUS 2 when driving with cruise control active
(ET042 Cruise control - speed limiter: CRUISE CONTROL) and the brake pedal is
depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command
RZ001 Fault memory.
If status ET415 becomes STATUS 2 without pressing the brake pedal, consult
the interpretation of statuses ET704 and ET705 Brake contact No. 1 and No. 2.
STATUS 3Clutch pedal depressed
Manual gearbox ONLY
The cruise control function is deactivated when the gearbox is not coupled to
the engine (clutch pedal depressed).
Status ET415 becomes STATUS 3 when driving with the cruise control active
(ET042 Cruise control - speed limiter: CRUISE CONTROL) and the clutch pedal
is depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command
RZ001 Fault memory.
If status ET415 becomes STATUS 3 without the clutch pedal being depressed,
consult the interpretation of status ET405 Clutch pedal.
If the vehicle is fitted with automatic transmission:
Test the multiplex network: check the configuration of the multiplex network in relation
to the vehicle's technical specification, especially the configuration of the automatic
transmission computer (see 88B, MULTIPLEXING).

STATUS 6
Gear 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 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.
This could occur when driving with cruise control active (ET042 Cruise control/
speed limiter: CRUISE CONTROL) and when there is a significant difference in
speed.
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 relatively flat terrain, contact the Techline.

ALP6 Idling speed too high or too low
NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Using the diagnostic tool, check that the injector codes (C2I) are correctly entered on the identification screen. If
not, configure the correct injector codes using command SC002 Enter injector codes.
Check the air inlet circuit by running TEST 2 Electrical circuit check.
Is the clutch clearance set correctly? Carry out the necessary repairs
Check that the computer connectors are properly locked.
Check the condition of the computer connections (bent pin, signs of corrosion, silicone, etc.).
If the connector(s) are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.

NOTESOnly consult this customer complaint after a full check with the diagnostic tool.
Check that there are no obstacles that might impede the accelerator pedal travel (carpet, point of resistance, etc.).
Using the diagnostic tool, check that the injector codes (C2I) are correctly entered on the identification screen. If
not, configure the correct injector codes using command SC002 Enter injector codes.
Visually check the condition of the engine wiring harness.
Is the clutch clearance set correctly? Carry out the necessary repairs.
Check that the engine has not sucked up its oil (engine racing).
Is the compression in order? Carry out the necessary repairs.
Check that the turbocharger is working properly.
Run TEST 11 Air line at the turbocharger.
Run TEST 10 Turbocharger solenoid valve check.
