Honda Civic 2007 Immobilizer Issue

Hi to all,
Honda Civic 2007 year, engine 1.8 16V Petrol, manual gearbox.
Country: South America

I need a tutorial about repair Immobilizer.
I have problem with signal from Immo, engine cranks but no start!
How do I check Can-Bus signal from ECU immobilizer or wiring problem?
I need a service manual.
Anyone can help me?
Many thanks.
