ET042 CRUISE CONTROL/SPEED LIMITER
NOTESNone.
NOT DETECTEDIf the vehicle is not fitted with cruise control - speed limiter function buttons, status
ET042 is permanently NOT DETECTED. This confirms that the cruise control/speed
limiter function is not present on the vehicle.
If the vehicle is fitted with cruise control or speed limiter function buttons and the main
switch is in the rest (or neutral) position and after the injection computer has been
programmed or reprogrammed, then status ET042 is NOT DETECTED.
To activate the cruise control or speed limiter function, press the main switch in
the cruise control position and then in the speed limiter position.
Return to rest position
The tool displays status ET042: INACTIVE.
If not, several steps must be checked:
1. Return to the page on testing the multiplex network with the CLIP program.
Repeat the multiplex network test. Re-establish dialogue with the injection
computer. Check ET042. If ET042 is INACTIVE, the injection computer has
detected the various positions of the main switch. The cruise control/speed
limiter is active.
2. If ET042 is still NOT DETECTED, check that the owner of the vehicle has not
had the cruise control - speed limiter function deactivated in the past. Contact
Techline.

CONTINUED 1
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.

SPEED LIMITER
When the driver presses the main switch in the speed limiter position, status
ET042becomes SPEED LIMITER.
If CRUISE CONTROL or INACTIVE appears although the switch was pressed in
the speed limiter 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 codes AP43 and 3FX of component 1546.
• Connection codes 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 1546 in
the cruise control position.
If these checks show incorrect values, replace the main 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, Electrical wiring repair,

ET415 CRUISE CONTROL/SPEED LIMITER DEACTIVATION
NOTESNone.
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.
NONEThis status is present on the diagnostic tool if:
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 without traction control requested (see 38C,
ABS).

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 4
Cancel button pressed
The cruise control/speed limiter function is deactivated each time the suspend button
is pressed.
Status ET415 becomes STATUS 4, when driving when:
– Either the cruise control is active, or
– the speed limiter is active,
– and the driver presses the 0 button.
This action deactivates the Cruise control/Speed limiter.
Reinitialise status ET415 on the injection computer by running command
RZ001 Fault memory.
If status ET415 becomes STATUS 4 without pressing the 0 button, consult the
interpretation of status ET703 Cruise control - speed limiter buttons and run fault
finding on the R/0 control button located on the right-hand side of the steering wheel.
