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 APC on the main switch connector.
– Connection code AP10 of component 1081.
Disconnect the main switch and with it in the rest position, check the insulation
between:
– Connection codes AP10 and 3FX of component 1081.
– Connection codes AP10 and 3PD of component 1081.
Check the continuity between connections AP10 and 3PD of component 1081 in the
speed limiter position.
Check the continuity between connections AP10 and 3FX of component 1081 in the
cruise control position.
If these checks are not in order, replace the switch.

STARTING
STATUS DEFINITIONPROHIBITED, this status indicates that starting is not possible.
AUTHORISED, this status indicates that starting is possible.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
Conformity check with the engine stopped and the ignition on, or engine running, and engine coolant
temperature > 80°C
AUTHORISED
Starting the vehicle is authorised when the UCH authorises starting.
Status ET076 changes to AUTHORISED if the vehicle cards are recognised and if the
engine immobiliser is inactive.
PROHIBITEDIf the card is not recognised by the UCH, starting the vehicle is prohibited.
Status ET076 is PROHIBITED and the vehicle cannot be started.
Run fault finding on the UCH and refer to the Technical Note for the vehicle to deal with
any faults (see87B, Passenger compartment connection unit).
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

IMPACT DETECTED
STATUS DEFINITIONNO: This status indicates that the airbag computer has not detected an impact.
YES: This status indicates that the airbag computer has detected an impact.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
This signal is transmitted by the airbag computer via the multiplex network.
Conformity check with the engine stopped and the ignition on, or engine running, and engine coolant
temperature > 80°C
NO
Under normal operating conditions, status ET077 is NO when the computer has
received no impact signal.
YESIf the vehicle has had an accident, the injection computer receives the impact signal via
the multiplex network and may switch off the ignition. Status ET077 is YES.
Switch off the ignition for 1 minute, then switch it on again, so the engine can be
started.
Carry out a multiplex network test and deal with any faults.
Clear the injection computer faults, even if no fault is present.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
