Warning light management:
Instrument panel display
The computer displays certain information on the instrument panel relating to engine operation. This concerns five
functions:
– the pre-postheating warning light,
– the coolant temperature warning light,
–the level 1 fault warning light (non-critical fault),
–the level 2 fault warning light (emergency stop),
–the EOBD (European On Board Diagnostic) warning light,
These six functions are represented by 3 warning lights and/or messages displayed by the on-board computer.
Orange pre-post heating/non-critical fault SERVICE warning light (severity 1)
This light is used both as an in-operation indicator light and as a system fault indicator:
– Continuously lit with + after ignition feed:
Indicates preheating of the spark plugs.
– Continuously lit with the Check injection message:
Indicates a level 1 fault (involving operation of the injection system in defect mode).
The driver should have the repairs carried out as soon as possible.
Temperature / red emergency STOP warning light (level 2)
This indicator light is used both as an in-operation indicator light and as a system fault warning light. It lights up for
3 seconds after the ignition is switched on (automatic test procedure managed by the instrument panel):
– Continuously lit:
Indicates engine overheating (the driver is free to choose whether or not to stop the vehicle).
– Continuously lit with the faulty injection message:
Indicates a level 2 fault (In this case, the injection is automatically cut after a few seconds).
The driver should carry out repairs as soon as possible.
ORANGE Excessive pollution EOBD warning light
Symbolised by an engine, it lights up for approximately 3 seconds when the ignition is switched on.
This warning light comes on if the system has one or more EOBD faults.
This warning light is used to alert the driver to injection faults that could lead to excessive pollution, or if the EOBD
system (European On Board Diagnostic) has been deactivated.
The injection computer requests illumination of the EOBD warning light for a present fault only after three
consecutive driving cycles.
The 3 second visual inspection when the ignition is switched on (automatic test procedure managed by the
instrument panel) is carried out by the injection computer.
Special particle filter ORANGE warning light or warning message (depending on instrument panel)
Only for Vdiag: 18, 1C, 54, 20, 58, 5C, 24, 26 and 60.
This warning light or message is used to warn the driver that the particle filter is loaded with particles, (see the soot
weight thresholds for illumination of the warning light for fault DF312 Speed request) due to driving conditions which
were not suitable for regeneration to take place. The driver must then drive as soon as possible at an average speed
of 48 mph (80 km/h) subject to the road conditions and authorised speed limits, until the warning light goes out.

13B-203
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check with the diagnostic tool.

PART B
1. No particle filter regeneration.
2.Write on the repair order the parameter and status relating to the last failure:
– Mileage of the last DF312 Speed request.
– Mileage of the last failures.
– Engine statuses of the last failures.
E.g.: PR787 = 2794 miles (4657 km); PR801 = 2760 miles (4600 km); engine status = STOPPED
3. Interpretation of the values written on the repair order by the service advisor for the customer:
Before the last time the particle filter warning light or message came on (appeared at the Mileage of the last
DF312), the customer had not respected the driving recommendations: the failure that occurred at the Mileage of
the last failure is due to the engine being switched off.
4. Explain to the customer the procedure to turn off the warning light, making use of the parameters noted in the
repair order: see PART D.
PART C
If Vdiag 18:
Reprogram the computer in Vdiag 1C.
Then apply the procedure corresponding to Vdiag 1C.
If Vdiag 1C, 54, 58, 20 and 24:
– Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary.
– Carry out an After-Sales regeneration with approval from the Techline.
– Follow the procedure for command SC017 Particle filter regeneration (see Interpretation of commands).
– Explain to the customer the procedure for regeneration when driving to avoid unnecessary repairs: see PART D.

PART D
Procedure to switch off the Particle filter message or warning light on the instrument panel
Certain types of driving can trigger illumination of the particle filter warning light or message, and activate fault
DF312. The customer must carry out a specific driving operation (cf. vehicle user manual) that consists of:
1. When the engine is warm, drive at a speed greater than 48 mph (80 km/h) for 2 minutes to trigger the
regeneration procedure.
2.Keep driving at an average speed of 48 mph (80 km/h), until the "particle filter" warning light or message on
the instrument panel goes out. In order for the procedure to succeed, it is necessary to drive without stopping
the engine or leaving the engine running at idle speed for an extended period of time. The regeneration time
depends on the vehicle and driving conditions but should last for 20 minutes maximum.
If regeneration fails when driving (the warning light does not go out or the service warning light comes on), check
the exhaust pipe for leaks or blockage. Repair if necessary. Proceed with an After Sales regeneration. Run
command SC017 (see Interpretation of commands).
If the fault is still present, contact the Techline.

PR873OIL OXIDATION SIGNAL
STATUS
DEFINITIONThis parameter indicates the vehicle distance in miles (km) when the oil oxidation
threshold is reached.
NOTESThis parameter should only be interpreted if the OCS (Oil Control System) program is
activated on the instrument panel. On the instrument panel computer, check the
configuration reading LC106 O.C.S: WITH.
Conformity check: Engine stopped and the ignition on, or Engine running and the engine coolant
temperature > 80°C without electrical consumers
The oil condition is calculated by the oxidation program in the injection computer, according to the number of
engine revolutions.
When this count reaches a certain threshold before the end of the oil service period, the injection computer sends
a signal to the instrument panel, which will display service due. Parameter PR873 corresponds to the vehicle
mileage at the time this signal is sent.
Then the instrument panel computer deducts 900 miles (1500 km) before displaying the message Service
required.
IMPORTANT:
When the message Service due appears on the instrument panel, the customer must have the oil changed within
the remaining 900 miles (1500 km).

PR875OIL DILUTION SIGNAL
STATUS
DEFINITIONThis parameter indicates the vehicle mileage in miles (km) when the oil dilution
threshold is reached.
NOTESThis parameter should only be interpreted if the OCS (Oil Control System) program is
activated on the instrument panel. On the instrument panel computer, check the
configuration reading LC106 O.C.S: WITH.
Conformity check: Engine stopped and ignition on, or engine running and engine coolant
temperature > 80°C without electrical consumers
The injection computer estimates the degree of engine oil dilution according to the customer's driving style.
When the dilution level reaches a certain threshold before the end of the oil change interval, the injection computer
sends a signal to the instrument panel which then displays Service required. Parameter PR875 corresponds to
the vehicle mileage at the time this signal is sent.
IMPORTANT:
When the message Service required appears on the instrument panel, the customer must arrange an immediate
oil change to prevent damage to the engine.

SC017
CONTINUED 1
PROCEDURE TO BE FOLLOWED:
To run this command, select the command mode on the diagnostic tool and run command SC017.
When regeneration is complete, a message will indicate whether regeneration was successful, and what
operations need to be carried out (filter replacement, whether an oil service is required, etc.).
DESCRIPTION OF THE PROCESS
particle filter regeneration takes place in 3 stages (values given as a guide only):
Heating phase: the speed is fixed or fluctuating around 3000 rpm.
– This phase lasts at least 6minutes, until the coolant temperature is above 80°C.
–Regeneration phase: the speed is fixed or varies around 2000 rpm. Engine injection is retarded. The exhaust
fumes rise in temperature and burn the soot retained in the particle filter. The particle filter downstream
temperature starts to rise after the particle filter upstream temperature due to the volume of the particle filter.
Then the combustion of the soot stored in the particle filter causes the particle filter downstream temperature
to increase, possibly reaching more than 700°C depending on the amount of soot in the filter (with a particle
filter upstream temperature of around 600°C). This phase lasts about 30 minutes.
–Cooling phase: the engine speed is fixed or varies around 2000 rpm.
– Engine injection returns to normal and the exhaust gases cool the particle filter.
– This phase lasts 3 minutes. At the end of this period, the engine speed returns to idle speed or remains fixed
at 2000 rpm.
The process lasts at least 40 minutes (the regeneration time will be increased depending on how long it takes
for the coolant to heat up to 80°C).
