The following article is actually part of 2005 Piaggio X8 400 workshop manual discussing about electrical system and wiring diagram. Herein you will learn on electrical component location, wiring diagram, ignition system, headlight and automatic starter section, battery recharge and starting, level indicators and signals section, electric fan, engine temperature sensor, immobilizer, stator, turn signals, lights, fuse, connectors, ECU, etc.
Here is a quotation from the article:
"The electronic ignition system is controlled by the control unit with the integrated Immobilizer system. The immobilizer is an anti-theft system that allows the vehicle to be operated only when it is started with coded keys recognised by the control unit. The code is integrated in a transponder in the key block. This allows the driver clear operation without having to do anything other than just turning the key. The Immobiliser system consists of the following components:
– electronic control unit
– immobilizer aerial
– master key with integrated transponder (brown key)
– service key with incorporated transponder (black key)
– HV coil
– diagnosis LED"
