INSTALLATION AND SETUP GUIDE
Correct connection diagram for fuel sensor imitation shown in the picture below.
After connecting additional resistor, installer must activate fuel sensor imitation mode in terminal,
following these steps:
1. Configure universal Digital pin to work as Digital output mode by setting P35 to 1
2. Enable “Fuel sensor imitation mode” by setting P33 to1
Note!!!
In case if universal digital pin is configured as digital output (P35 = 1), then this pin cannot be used
as digital input at the same time.
