Injection warning light
Vehicles using the high pressure diesel system are fitted with two injection warning lights used during the preheating
phase and in case of an injection fault (or engine overheating).
WARNING LIGHT PRINCIPLE
!When ignition is switched on, the preheating light is lit during the preheating phase and then goes out (see section
13 "Pre-postheating control").
!When there is a fault on the injection system the "fault" warning light lights up. These faults are:
– internal computer fault,
– engine speed fault (the vehicle doesn't start),
– main relay or low pressure fault (the vehicle doesn't start),
– injector fault,
–TDC sensor coherence fault and camshaft sensor,
– rail pressure sensor fault,
– rail pressure regulator fault,
– accelerator potentiometer fault,
– engine immobiliser fault,
– computer supply voltage fault,
– engine overheating.
NOTE: the OBD warning light (symbolised by an engine), visible when the ignition is switched on, is never visible
when the engine is running.
