ET415
(CONTINUED 4)
STATUS 10Monitoring by 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 present or stored faults (see Interpretation of faults).
Reinitialise status ET415 on the injection computer by running command RZ007
“Fault memory”.
If status 10 continues, 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.

CRUISE CONTROL/SPEED LIMITER BUTTONS
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system programming
functions.
INACTIVEStatus ET703 becomes "INACTIVE" when none of the cruise control/speed limiter
buttons is pressed. These buttons are located on the steering wheel.
If status ET703 does not display "INACTIVE",
●check the condition of the cruise control/speed limiter +/- button and the condition of
its connector,
check the condition of the cruise control/speed limiter R/0 button and the condition of its
connector.
INCREASEStatus ET703 becomes PLUS when the cruise control/speed limiter + button is pressed.
This button is on the steering wheel, on the left-hand side.
If status ET703 does not display PLUS, check the condition of the cruise control/speed
limiter +/- button, and the condition of its connector. Repair if necessary.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR 364/370 Mechanical,
Electrical equipment 88C, Airbag and seat belt pretensioners, Driver's front
airbag, Removal - Refitting).
●Measure the resistance on the button between tracks P1 and P0 while pressing
the “+” button of component 331.
If the resistance is not approximately 300 , check the continuity of the connection when
the button is not pressed.
If there is continuity, replace the +/- control button.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Repair precautions), repair the wiring, otherwise replace it.
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.

DECREASEStatus ET703 becomes MINUS when the cruise control/speed limiter - button is pressed.
This button is on the steering wheel, on the left-hand side.
If status ET703 does not change to MINUS, check the condition of the cruise control/
speed limiter “+/-” button, and the condition of its connector. Repair if necessary.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR 364/370 Mechanical,
Electrical equipment 88C, Airbag and seat belt pretensioners, Driver's front
airbag, Removal - Refitting).
Repair if necessary.
Measure the resistance on the button between tracks P1 and P0 while pressing the
“-” button of component 331.
If the resistance is not approximately 100 , check the continuity of the connection when
the button is in rest position.
If there is continuity, replace the “+/-” control button.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Repair precautions), repair the wiring, otherwise replace it.
SUSPENDStatus ET703 becomes SUSPEND when the cruise control/speed limiter R button is
pressed. This button is located on the steering wheel, to the right.
If status ET703 does not change to SUSPEND, check the condition of the cruise control/
speed limiter R/0 button, and the condition of its connector.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR 364/370 Mechanical,
Electrical equipment 88C, Airbag and seat belt pretensioners, Driver's front
airbag, Removal - Refitting).
Measure the resistance on the button between tracks P1 and P0 while pressing the
“0” button of component 331.
If the resistance is not approximately 0 , replace the R/0 control button.
If there is continuity, replace the “R/0” control button.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Repair precautions), repair the wiring, otherwise replace it.
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
