– 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 show incorrect values, replace the main switch.

following connections:
●Connection code 3FX,
●Connection code 3PD,
between components 1081 and 120.
Also check the engine management computer connectors.
If there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,

ET076
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.

ET088
REQUEST TO START COMPRESSOR
STATUS DEFINITIONACTIVE: This status indicates that the compressor is engaged.
INACTIVE: This status indicates that the compressor is not engaged.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
Engine running, engine coolant temperature > 80 °C
ACTIVE
Status ET088 becomes ACTIVE if there has been a request for air conditioning (“AC” or
“AUTO” button pressed, with maximum cold) and if status ET004 Air conditioning
authorisation 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 activation, it sends the compressor
activation request to the Protection and Switching Unit (Vdiag 18, 1C, 20 only) 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 activation, it sends the compressor
activation request to the Protection and Switching Unit (Vdiag 18, 1C, 20 only) and
status ET088 becomes ACTIVE.
If there has been no compressor activation request and status ET088 remains ACTIVE
(see62A, Air conditioning).
Note:
Compressor operation is only authorised when the engine is running.
Compressor switch-on is finally requested by the Protection and Switching
Unit (Vdiag 18, 1C, 20 only).
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

INACTIVE
Status ET088 is INACTIVE when there has been no air conditioning request and
when compressor activation has not been authorised (ET004 Air conditioning
authorisation is NO or when the driver switches off the air conditioning).
If compressor activation has been requested and status ET088 remains INACTIVE
(see 62A, Air conditioning).
Note:
Compressor operation is only authorised when the engine is running.
Compressor switch-on is finally requested by the Protection and Switching Unit
(Vdiag 18, 1C, 20 only).

INJECTOR CODE USE
STATUS DEFINITIONNO: This status indicates that injector code use is not available.
YES: This status indicates that injector code use is available.
FA U LT Y: This status indicates that there has been an injector code use fault.
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
NO
Status ET104 is NO if the computer is not configured to interpret the IMA codes
(individual injector correction)
Use command SC002 “Enter injector codes” (see Interpretation of commands).
YESStatus ET104 is YES if the IMA option (individual injector correction) is activated in
the injection computer.
All the injectors have IMA codes etched on the bakelite body, but not all computers
use them.
In the case of a computer configured with the IMA option, the injector codes must be
entered into the injection computer in the following scenarios:
– when one or more injectors is replaced,
– when the injection computer is replaced,
– when the injection computer is reprogrammed.
If the injector codes are not programmed after these operations, fault DF276
“Injector code programming” will be present and the engine will operate in defect
mode.
Use command SC002 Enter injector codes (see Interpretation of commands).
FA U LT YStatus ET104 is FA U LT Y if the computer does not have IMA codes in the memory.
Fault DF276 Injector code programming is present and the engine runs in defect
mode.
Run command SC002 Enter injector codes (see Command summary table).
If at the end of the procedure status ET104 remains FA U LT Y, contact Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

SET NUMBER OF PASSENGER COMPARTMENT HEATING
RESISTORS
STATUS DEFINITIONYES: This status indicates that the number of activated passenger compartment
heating resistors is set by the injection computer.
NO: This status indicates that the number of passenger compartment heating resistors
can be freely controlled by the UCH.
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
YES
Depending on the requirements of the injection system (power requirement, torque
reduction, etc.), the injection computer fixes the number of controlled passenger
compartment heating resistors (no more, no less).
Status ET111 becomes YES when the number of activated passenger compartment
heating resistors is set by the injection computer.
NODepending on the requirements of the injection system (power requirement, torque
reduction, etc.), the injection computer fixes the number of controlled passenger
compartment heating resistors (no more, no less).
Status ET111 becomes NO when the number of activated passenger compartment
heating resistors can be freely controlled by the UCH.
