Instrument panel display
The computer manages the data display on the instrument panel relating to engine operation. This covers five
functions: the OBD warning light for European On Board Diagnostics (EOBD), pre-postheating, coolant temperature,
and Level 1 (non critical fault) and Level 2 (emergency stop) engine faults. These five functions are represented by
five warning lights or messages displayed by the trip computer.
Pre-postheating warning light
This warning light indicates that preheating is active.
Engine coolant temperature warning light
This warning light is used as an engine overheating indicator.
–In the event of overheating, it is up to the driver whether to stop the vehicle or continue driving.
OBD warning light
The OBD fault warning light is used to warn the driver of the presence of injection faults producing excessive
pollution or that the EOBD system is deactivated.
The injection computer requests illumination of the OBD warning light for a present fault only after three consecutive
driving cycles.
The visual check of the warning light when the power is switched on (automatic test procedure managed by
the instrument panel) is carried out by the injection computer. It lasts 3 seconds or until the engine starts for
the New Twingo and Kangoo 2.
If a confirmed OBD fault causes the OBD warning light to come on, there should be no flashing after the warning
light illumination test. The instrument panel will also display the message: Check emission control.
The gearbox computer, if fitted, may also request the illumination of this warning light.
Level 1 warning
If there is a minor fault, the computer may request a level 1 warning to be displayed. Usually, the instrument panel
switches on the SERVICE warning light and sends out a "Check the injection" message. Refer to the operation of the
instrument panel (see 83A, instrument panel). Note:
This warning light comes on only if the vehicle is EOBD approved.
Note:
The SERVICE warning light will come on if the instrument panel is configured as cruise control - speed
limiter present, but the function has not yet been detected by the injection computer.

COMPUTER REPLACEMENT OR REPROGRAMMING OPERATIONS
Before removing any old computer as an After-Sales operation, save the following data using the diagnostic
tool:
–The C2I (individual injector correction) parameters and the engine adaptives using command SC003 Save
computer data.
The system can be programmed by the diagnostic socket using the RENAULT CLIP diagnostic tool (refer to
Technical Note 3585A, Computer programming and reprogramming procedure, and follow the instructions
provided by the diagnostic tool).
After replacing or reprogramming the computer
–Switch the ignition off and then on again.
–Use the diagnostic tool command SC001 Enter saved data to restore the C2I and the engine adaptives.
–On Kangoo 2, use the diagnostic tool command SC040 Speed limiter, if necessary.
–Use command AC028 Static test to reinitialise the computer (fan assembly, etc.).
–Switch the ignition off and then on again.
–When changing the pump, refer to the high pressure pump replacement procedure (consult Technical Note
5011A, Repriming Delphi high pressure pumps on K9K engines).
–Activate the starter without releasing the key until the engine starts (the engine start time can be up to
20 seconds).
–Stop the engine (to initialise the computer) and wait 30 seconds.
–Switch the ignition back on and use the diagnostic tool to carry out the following steps:
–Run command VP010 Enter VIN.
–After injection system programming, stored faults may appear on other computers. Clear the memory of these
computers.
–Switch the ignition off and then on again. IMPORTANT
–Switch on the diagnostic tool (mains or cigarette lighter supply).
–Connect a battery charger.
–Switch off all electrical consumers (lights, interior lights, air conditioning, radio/CD, etc.).
Wait for the engine to cool (engine coolant temperature less than 60
°C and air temperature less than 50°C).
IMPORTANT
Before reprogramming the injection computer, move the main cruise control - speed limiter switch to the rest
position. The information about the cruise control or the speed limiter displayed on the instrument panel
disappears.
Otherwise, if the main switch remains in the cruise control or speed limiter position during and after reprogramming,
the cruise control - speed limiter function will not be operational.
The procedure for resetting the function is as follows:
Vehicle ignition on.
Main switch in rest position (the computer then detects the rest position).
Switch in the Cruise control position to activate the Cruise control function.
Switch in the Speed limiter position to activate the Speed limiter function.
IMPORTANT
AFTER A PROGRAMMING OPERATION, DO NOT CONNECT THE BATTERY FOR AT LEAST 30 minutes (to
carry out other work on the vehicle).

ET003ENGINE IMMOBILISER
STATUS DEFINITIONACTIVE: This status indicates that the immobiliser is active.
INACTIVE: This status indicates that the immobiliser is inactive.
NOTESACTIVE: ET003 "ENGINE IMMOBILISER" shows the vehicle protection status.
This Verlog 4 type immobiliser function is managed by the UCH computer and the
injection computer.
Before any starting request, the computer is protected.
When a starting request is made, the injection computer and the UCH exchange
authentication data via the multiplex network. This determines whether the engine start
is authorised or denied.
After more than 5 consecutive failed authentication attempts, the injection computer
goes into protection (anti-scanning) mode and no longer tries to authenticate the UCH
computer.
It only leaves this mode when the following sequence of operations is carried out:
–The ignition is left on for at least 5 seconds,
–The ignition is switched off,
–The injection computer self-supply cuts out when it should (the time varies according
to engine coolant temperature).
Conformity check: Engine stopped, ignition on or engine running.
"ACTIVE"If status ET003 is ACTIVE, see 82A, Engine immobiliser.
"INACTIVE"When the ignition is switched on and when driving, status ET003 should be INACTIVE,
if this is not the case, see 82A, Engine immobiliser.

STATUS DEFINITIONYES: This status indicates that the immobiliser code has been programmed.
NO: This status indicates that the immobiliser code has not been programmed.
NOTESThe injection immobiliser code is not written in the injection computer.
The programming of this code in the injection computer is managed by the UCH.
To carry out programming:
–establish communication with the UCH see 87B, Passenger compartment
connection unit.
–run command SC017 Program injection immobiliser code,
–follow the instructions for the procedure.
As long as this phase has not been completed, ET006 "Code programmed" is "NO".
IMPORTANT:
the immobiliser code is written in the injection computer memory at the end of the
computer auto-feed phase. Do not disconnect the battery before the end of this phase.
Conformity check: Engine stopped, ignition on or engine running.
YESStatus ET006 is YES if dialogue is possible between the UCH computer and the injection
computer and the key code is recognised.
The engine is only authorised to start if the code is recognised by the UCH computer and
if status ET003 Immobiliser is INACTIVE.
In the event of a fault, (see 87B, Passenger compartment connection unit,
conformity check).
