A fault on these sensors could lead to incorrect fault finding on the accelerometer.
Conditions for applying fault finding procedures to stored faults:
The fault is present with the engine idling.
Check the conformity of the injectors fitted to the vehicle in relation to the type of vehicle and engine number
(low, high or very high pressure injector).
Check the condition and connection of the accelerometer connector.
Repair if necessary.
Check the connection and condition of the brown 48-track connector B of the computer and check the sensor
shielding on track K1.
Repair if necessary.
Check the insulation, continuity and the absence of interference resistance on the following connections:
Sensor connector track 1 Track F1 computer connector B
Sensor connector track 2 Track G1 computer connector B
Repair if necessary.
Check that the C2I is correctly entered on the computer.
Check that the accelerometer is secured on the engine.
Disconnect and reconnect the accelerometer sensor to accomplish fast programming.
Carry out a road test followed by another check with the diagnostic tool.

INACTIVE
When the main switch is in rest position (or neutral), status ET042 is INACTIVE.
If CRUISE CONTROL or SPEED LIMITER appears despite the main switch being in
the rest (or neutral) position, carry out the following operations:
Check the connections of the cruise control/speed limiter main switch.
Check for +12 V after ignition feed on the main switch connector.
• Connection code AP43 of component 1546.
Disconnect the main switch and with it in the rest position, check the insulation
between:
• Connection code AP43 and 3FX of component 1546.
• Connection code AP43 and 3PD of component 1546.
Check the continuity between connections AP43 and 3PD of component 1546 in
the speed limiter position.
– Check the continuity between connections AP43 and 3FX of component
1546in the cruise control position.
If these checks are not in order, replace the switch.
Check the continuity, insulation, and the absence of interference resistance on
the following connections:
• Connection code 3FX,
• Connection code 3PD,
between components 1546 and 120.
Also check the engine management computer connectors.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the wiring, otherwise replace it.

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).

Only perform these tests if the statuses do not correspond with the system programming
functions.

buttons are pressed. These buttons are located on the steering wheel.
To remove the driver's airbag to perform the checks in complete safety.
(see 88C, Airbag and pretensioners)
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.
Repair if necessary.
