VIII - DRIVER'S INFORMATION FUNCTION
A - DIAGNOSTIC LED (V1300)
Normal LED operation:
• the LED illuminates when the ignition is switched on.
• after the ignition is switched on, the LED extinguishes after a 4 second timer.
Abnormal LED operation:
• the LED illuminates when the ignition is switched on,
• the LED remains illuminated.
B - RISK OF THE PARTICLE FILTER CLOGGING
In the event of prolonged idling, regeneration assistance is ineffective (exhaust
gas temperature not sufficient).
The filter clogs up with particles.
The injection ECU informs the BSI.
The BSI requests that a message is displayed on the multifunction screen (risk of
particle filter clogging) in the following cases: particle filter fault (particle filter
overloaded).
The aim is to encourage the driver to adapt his driving to facilitate particle filter
regeneration.
Within 100 kilometres after the message appears, the customer must drive for at
least 3 minutes at a speed greater than 50 km/h which should cause the
message to disappear.
Failure to comply with this recommendation will lead to the following fault: particle
filter clogged.
The injection ECU informs the BSI which:
• requests that the diagnostic LED is illuminated,
• requests that a message is displayed on the multifunction screen (antipollution
problem).
