20- If very different resistive values are detected,
replace the air injector.
GO TO point 19
21- Check the air injector winding negative insu-
lation.
1 - any pin of the injector> or = 1MOhm
YES point 23 NO point 22
22- Replace the air injector.
GO TO point 21
23- Connect the specific tool to the ECU. Connect
the air injector connector. Check the presence of
voltage to the ECU.
1 - 13 = V battery (engine off and any position
of the switch)
YES point 25 NO point 24

24 - Voltage is close to 0V and the injector is open. Carefully check the control line insulation. Replace
the ECU if required.
25 - The air injector control circuit is efficient. The air injector opening time can be checked when the
engine is running by the «parameters» menu
AIR INJECTION T. mS =
6 ÷ 7 mS (start up at 20° C)
~ 1.6 mS (idle at 20° C)
~ 1.4 mS (idle at 60° C)
The values are indicative but useful for diagnostics. Command failures or unusual opening times are
always caused by the ECU.
