This procedure is useful during maintenance tocheck the filter efficiency in delivery.
Connect the diagnostic tester dwg. 020460Y.
Connect the fuel pressure check kit dwg.020480Y.
1
- Select the diagnostic tester menu on the
"ACTIVE DIAGNOSIS" function.
Select the "PUMP DIAGNOSIS" function.
The pump starts for 30 seconds.
YES
go to 2
2
-
Bleed for a few seconds.
Make sure that there are no leaks.
Using pliers with flat and long tips, temporarily
clamp the return duct by the extension of the
specific
tool dwg. 020480Y with pump power supply
voltage higher than 12 V, check the system
maximum pressure.
Maximum pressure = > 600 KPa (6 BAR)
YES
go to 3
NO
go to 4
3
-
Check the system seal.
Start the pump for 30 seconds by the diagnostic tester dwg. 020460Y.
When the pump stops, wait 3 minutes.
Check the system pressure.
Fuel pressure = over 200
KPa (2 BAR)
YES
go to 5
NO
go to 6
4
-
If pressure is lower, carefully check the voltage with pump under stress.
If voltage is higher than 12 V, replace the pump.
5
- The system seal is efficient.
Check the free flow rate.
GO
to 16
6
- Repeat the test. When the pump stops,
use pliers with flat and long tips to temporarily
clamp the return duct by the extension of the
specific tool. This causes an increase of the
fuel pressure.
GO
to 7
7
-
Check whether the pressure decreases with the same trend as the system when free from
bottlenecks
GO
to 8
