CRUISE CONTROL/SPEED LIMITER
NOTESSpecial notes:
Only perform the tests if the statuses do not correspond with the system programming
functions.
NOT DETECTEDIf the vehicle does not have buttons for the cruise control or speed limiter functions,
status ET042 is permanently NOT DETECTED. Confirmation of the absence of the
cruise control or speed limiter function on the vehicle.
If the vehicle is fitted with cruise control or speed limiter function buttons, the main switch
is in rest (or neutral) position and the injection computer has been programmed or
reprogrammed, 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 application. Repeat
the multiplex network test. Re-establish dialogue with the injection computer. Check
status 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 NOT DETECTED, check that the owner of the vehicle has not at some
point in the past, asked for the cruise control/speed limiter to be disabled. 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.

INACTIVEWhen the main switch is in the rest (or neutral) position, status ET042 is INACTIVE.
If "CRUISE CONTROL" or "SPEED LIMITER" appears despite the main button being in
the rest position (or neutral), carry out the following operations:
Check the connections of the cruise control/speed limiter main switch.
Check for + 12 V APC on the main switch connector.
Disconnect the main switch and with it in the rest position, check the insulation
between:
Injection computer A black,
●32-track track A2 Cruise control On/Off button, 6-track
connector track A3
●32-track track C3 Speed limiter On/Off button, 6-track
connector track B1
– Check the continuity between track C3 (injection computer, connector A, black) and
the speed limiter On/Off button 6-track connector track B1 in the speed limiter
position.
– Check the continuity between track A2 (injection computer, connector A, black) and
the cruise control On/Off button 6-track connector track A3 in 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: Injection computer connector A, black,
●32-track track A2 Cruise control On/Off button, 6-track
connector track A3
●32-track track C3 Speed limiter On/Off button, 6-track
connector track B1
Repair if necessary.

speed limiter position, carry out the following operations:
Check the connections of the cruise control/speed limiter main switch.
Check for + 12 V APC on the main switch connector.
Disconnect the main switch and with it in the rest position, check the insulation between:

– Check the continuity between track C3 (injection computer, connector A, black) and
the speed limiter On/Off button 6-track connector track B1 in the speed limiter
position.
– Check the continuity between track A2 (injection computer, connector A, black) and
the cruise control On/Off button 6-track connector track A3 in the cruise control
position.
If these checks show incorrect values, replace the main switch.
