Defect | Cause | Solution | |
Pilot lamp electrical part: | |||
It doesn't light up after the contact switch has been connected | - Lack of electric supply - Defective relay K15 - Defective electronic module - Defective thermal sensor (19) - Interrupted electrical wiring or short-circuit | - Check electrical part. - Check relay. - Check electronic module. - Replace thermal sensor. - Repair electrical wiring. | |
It doesn't remain lit during the 20-second time or it remains lit after this time | - Damaged timer on the electronic module - Damaged thermal sensor (19) | - Check timer electronic part. - Check the engine thermal sensor operation. | |
Heating glow plug (18): It doesn't heat | - Lack of electric supply - Poor, insufficient supply current - Defective heating glow plug (18) | - Check the cause. - Check wiring and possible short-circuits. Measure electric values. - Replace heating glow plug. | |
Fuel supply Electromagnetic valve (3): It doesn't receive fuel pressure or the pressure is insufficient | -Hollow screw (16) with clogged dosing orifice - Loose or damaged pipeline (12) | - Check the fuel passage on the hollow screw. - Check the state of the fuel filters. - Check pipeline and tighten the connections or replace them. | |
Valve (3) receives electrical current normally, but it doesn't perform the switching | - Deficiency on the valve's electromagnetic activation (3) | - Replace the whole valve (3). | |
Valve (3) receives fuel pressure, the electrical supply is normal, but it doesn't inject fuel | - Deficiency on the mechanical parts of the valve (3) | - Replace the whole valve (3). | |
Fuel injector (11) assembly: Solenoid valve (3) is in order, but the injector assembly (4) doesn't spray or do it deficiently | - Injector assembly (4) with saturated filter or deformed spray orifice | - Replace injector assembly (4) and check the state of the combustion chamber. | |
Cold start causes smoke during start | - Glow plug doesn't heat enough - Defective glow plug (18) - Injector changed (4) | - Check the supply voltage and the amperage. - Replace glow plug (18) - Replace injector assembly. (4). |
