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.

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
– the special Regenerate particle filter warning light is lit or a warning message is
displayed on the instrument panel,
– A specific kind of driving is required to bring about regeneration of the particle filter
when driving.
Priorities when dealing with a number of faults:
Firstly, deal with the following faults:
–DF308 Particle filter clogged if it is present or stored.
–DF311 Failed regenerations limit exceeded if it is present.
–DF315 Particle filter diff* pressure sensor if it is present or stored.
–DF717 Particle filter upstream pressure if it is present or stored.

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.
