- Remove the 2 5 A fuses
- Remove the connector of the fuel pump
GO TO point 41
Specific tooling

41 - Remove the burnt 20A fuse. Check the mass
insulation of the supply line of pin 17 with the
switch on «ON»
1 - 17 = Ohm infinite
YES point 43 NO point 42
42 - Restore the mass insulation of the wiring or of
the key switch.
GO TO point 34
43 - Re-connect the specific tool with the ECU
Mount a new 20A. fuse Check the following con-
ditions:
1 - 17 = battery voltage (switch on «ON»)
1 - 17 = 0 Volt (switch on «OFF»)
YES point 45 NO point 44
44 - IlThe fuse is again burnt. Check the wiring more accurately and, if necessary, replace the ECU
GO TO point 34
45 - Make a good visual check of the wiring to avoid possible causes for short circuits. Reconnect the
5 A fuses. If there are no anomalies, check any possible short circuits or absorbance on the supply
circuit of the fuel pump.
