1. OPERATING SAFETY
Activation of the warning lights
The SIM32 injection system manages the illumination of three warning lights according to the severity of the faults
detected, to inform the customer and to assist with fault finding.
The injection computer manages the activation of the warning lights on the instrument panel. These warning lights
illuminate during the starting phase and in the event of an injection fault or engine overheating.
The warning light activation commands are sent to the instrument panel.
Warning light illumination principle
When the ignition is switched on, the OBD (On Board Diagnostic) warning light is illuminated for approximately
3 seconds and is then extinguished.
If there is an injection fault (severity level 1), the SERVICE warning light is illuminated.
It indicates a reduced level of operation and a limited safety level.
The user must carry out repairs as soon as possible:
–motorised throttle valve,
–accelerator pedal potentiometer,
–inlet manifold pressure sensor,
–computer,
–actuator feed,
–the computer power supply,
–turbocharger pressure sensor (for D4FT 780).
For faults requiring the driver to stop the engine quickly, the severity level 2 warning light is illuminated.
If a fault causing excessive exhaust gas pollution is detected, the orange OBD warning light engine symbol is
illuminated:
–the light flashes if the fault could lead to a risk of destroying catalytic converter (destructive engine misfire). If this
happens, the vehicle must be stopped immediately.
–the light is permanently illuminated if the emission control standards are not met (pollutant engine misfire,
catalytic converter fault, oxygen sensor fault, inconsistency between the oxygen sensors and a fuel vapour
absorber fault).
Mileage travelled with fault
The parameter PR106 Mileage counter fault warning light illuminated displays the mileage covered and
illuminates one of the injection fault warning lights: fault severity level 1 (amber) and 2 (red). The parameter
PR105 Mileage counter OBD fault warning light illuminated displays the mileage covered and illuminates the
OBD warning light.
This counter is reset to 0 using the diagnostic tool via the command RZ001 Fault memory.

3. INTERSYSTEM ENGINE FUNCTIONS
The intersystem connections relating to the particular requirements of the injection are as follows:
–The instrument panel computer requests illumination of the OBD warning light to warn of an emissions control fault.
–Requests illumination of the Severity level 1 warning light to warn of an operational safety fault related to the
injection system.
–Requests illumination of the Severity level 2 warning light to warn of an operational safety fault or engine
overheating.
–Requests activation of the fan assemblies (GMV) for engine cooling, but also for the air conditioning system and
sequential gearbox (BVR) functions.
–Request for air conditioning compressor switch-off for engine programming requirements such as starting,
performance, anti-stall, overspeed, etc.
–Passenger Compartment Heating Resistor cut-off or setting request for engine programming requirements such as
starting, performance, anti-stall, overspeed, etc.
–Request for gradual engagement of electrical consumers and to limit power: This last function is made possible by
the alternator being operated. This is used to improve the engine handling in critical operating phases, mainly when
idling and when starting. These requests are sent by the UCH via the CAN network where they are converted before
being sent to the alternator.

NOTESPriorities when dealing with a number of faults:
Deal with the faults DF084 Actuator relay control circuit and DF046 Battery voltage
if they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present with the engine running or when using command
AC117 Upstream O2 sensor heating.

If there is no + 12 V:
–Disconnect the battery

Use the "universal bornier" to check the insulation and continuity of the following connection:
●3FB between components 887 and 1337.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Reconnect the Protection and Switching Unit connector and reconnect the battery.
If the + 12 V is still not present on the upstream oxygen sensor connector with the ignition on, there is a fault with
the Protection and Switching Unit.
Run fault finding on the UPC, component code 1337 (see 87G, Engine compartment connection unit).
Check the condition of the connector for the engine management computer (see Wiring Diagram Technical Note
for NEW TWINGO, E33, CLIO III, or MODUS, component code 120).
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Use the "universal bornier" to check the insulation and continuity of the following connection:
●3GF between components 887 and 120.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check for an earth on connection 3GH of the upstream oxygen sensor during activation of command AC117
Upstream O2 sensor heating.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Measure the heating resistance of the upstream oxygen sensor:
If the resistance of the upstream oxygen sensor is not between:
●8 Ω < X < 10 Ω at 20 ˚C, replace the upstream oxygen sensor.
If the fault is still present, contact the Techline.
AFTER REPAIRFollow the instructions to confirm repair:
- If the fault is present, continue to deal with the fault.
- If the fault is stored, ignore it.
Deal with any other faults.
Clear the stored faults.
