SYSTEM SET-UP PROCEDURE

GALILEO
Set-up procedure
After performing all electrical connections of the GALILEO harness, proceed as follows to set up the
system:
1) connect the GALILEO E.C.U. to the PROGRAMMING TESTER by means of the appropriate harness.
2) Configure the E.C.U. according to the characteristics of the vehicle and of the input signals (see
"VEHICLE CONFIGURATION MENU").
3) By using the TESTER PROGRAMMER, select "DISPLAY PARAMETERS" and start the engine with the fuel
switch on PETROL position.
4) Wait until the Oxygen Sensor is hot and make sure that it works correctly by toggling between either
0÷1 V, or 0÷5 V, depending on the type of Oxygen Sensor present on the vehicle. Moreover, check for
proper operation of the T.P.S. and of the RPM indicator.
If the above procedures are performed with successful results, check the following:
• that the GREY and PURPLE wires have been properly connected and not juxtaposed (see schematic);
• that the GROUND is properly connected and that there are no false contacts;
• that the OXYGEN SENSOR works properly on PETROL. Perform this check by using a digital multimeter.
Replace the sensor if damaged;
• that the BLUE-YELLOW and BROWN wires have been properly connected. Moreover, by using the TESTER
PROGRAMMER, make sure that the configuration of the GALILEO E.C.U. is appropriate for the type of
signal that is read by these two wires.
5) Switch to GAS; accelerate and decelerate a few times, making sure that the engine is not stalling.
6) Bring the engine to 3000÷3500 RPM and wait until the E.C.U. has memorized the default position (the
factory default is 100 steps).
7) Bring the engine back to idle and adjust the idle mixture at the regulator, making sure by using the
tester that the carburetion is correct.
The optimal position of the stepper motor during the GAS mode should be within 50÷60 steps on L.P.G.,
while 70÷120 steps is the correct range for C.N.G.. If the default of the stepper motor is significantly
different from the above values, we suggest checking for correct mixer, and/or correct operation of the
pressure regulator.
