SPEED LIMITER
CONTINUED 1
Method to be applied for Mégane II ph2 and Kangoo II:
When the driver presses the main switch in the speed limiter position, status ET042
becomes 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 APC on the main switch connector.
●Connection code AP43 of component 1081.
Disconnect the main switch and with it in the rest position, check the insulation
between:
●Connection code AP43 and 3FX for component 1081.
●Connection code AP43 and 3PD for component 1081.
– Check the continuity between connections AP43 and 3PD of component 1081 in
the speed limiter position.
– Check the continuity between connections AP43 and 3FX of component 1081 in
the cruise control position.
If these checks show incorrect values, replace the main switch.
Check the insulation, continuity and the absence of interference resistance on the
following connections:
●Connection code 3FX,
●Connection code 3PD,
between components 1081 and 120.
Also check the engine management computer connectors.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A,
Repairing electrical wiring, Wiring: Precautions for repair), repair the wiring,
otherwise replace it.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

STARTING
STATUS DEFINITION"PROHIBITED": This status indicates that starting is not possible.
"AUTHORISED": This status indicates that starting is possible.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
>80 °C
"PROHIBITED"
Refer to the fault finding note for the UCH, (see 87B, passenger compartment
connection unit).
"AUTHORISED"In the event of a fault, refer to the UCH fault finding note, (see87B, passenger
compartment connection unit).
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

ET077
IMPACT DETECTED
STATUS DEFINITION"YES": This status indicates that the airbag computer has detected an impact.
"NO": This status indicates that the airbag computer has not detected an impact.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
>80 °C
YES
If the vehicle has had an accident, the injection computer receives the impact signal via
the multiplex network and may switch off the ignition.
Switch off the ignition for 10 seconds, then switch it back on, so the engine can be
restarted.
Test the multiplex network (see88B, Multiplexing), and deal with any faults.
NOIn normal operating conditions, status ET077 is NO if the injection computer has
received no impact signal.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

Only perform these tests if the status does not correspond with the system
programming functions.
Heating and air conditioning is present depending on the vehicle's equipment level.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature

ET088
REQUEST TO START COMPRESSOR
STATUS DEFINITION"ACTIVE": This status indicates that the compressor activation request is active.
"INACTIVE": This status indicates that the compressor activation request is not active.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
>80 °C
ACTIVE
Status ET088 becomes ACTIVE if there has been a request for air conditioning (press
on AC or AUTO button, with maximum cold request) and status ET004 is YES.
The selection is made on the air conditioning control panel, the request for air
conditioning is transmitted to the UCH which in turn transmits the request to the
injection computer which either authorises or does not authorise compressor activation.
If the injection computer authorises compressor switch-on, the injection computer
sends the compressor switch-on request to the UPC and status ET088 becomes
""ACTIVE" (Climate control).
If the vehicle is equipped with manual air conditioning, the air conditioning request is
transmitted from the air conditioning control panel to the UCH which then accepts or
does not accept the air conditioning compressor coming on depending on the operating
status of the passenger compartment fan. When the request has been accepted, the
request to switch on the compressor is transmitted to the injection computer which
either authorises or does not authorise the compressor to start.
If the injection computer authorises compressor switch-on, it sends the request for
compressor switch-on to the UPC and status ET088 becomes "ACTIVE".
If there has been no compressor switch-on request and status ET088 remains
"ACTIVE", see62A, Air conditioning.
Note: Compressor operation is only authorised when the engine is running.
Compressor activation is commanded by the UPC.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

INACTIVE
Status ET088 is "INACTIVE" when no air conditioning request has been made. When
compressor switch-on has not been authorised (ET004 "AC authorised" is "NO") or
when the driver switches the heating and air conditioning system off.
If there is a compressor switch-on request and status ET088 remains "INACTIVE",
see62A, Air conditioning.
Note: Compressor operation is only authorised when the engine is running.
Compressor activation is commanded by the UPC.
