PIAGGIO Runner 125 - Immobiliser

Immobiliser
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 built-in transponder (red key) with big handgrip
- service key with built-in transponder (red key with small handgrip)
- H.V. coil
- Diagnostic LED
The diagnosis led also works as a blinking light to deter theft. This function is activated every time the
ignition switch is turned to the "OFF" position, or the emergency stop switch is turned to the "OFF"
position. It remains activated for 48 hours in order not to affect the battery charge. When the ignition
switch is turned to the "ON" position, the deterring blinker function is deactivated. Subsequently, a flash
confirms the switching to the "ON" status. The duration of the flash depends on the programming of the
electronic control unit If the LED is off regardless of the position of the ignition-key switch and/or the
instrument panel is not initiated, check if:
•
there is battery voltage
•
fuses 2 and 4 are working properly
•
there is power to the control unit as specified below:
Remove the front shield to access the control unit. Disconnect the two connectors and check the fol-
lowing conditions:
With the key switch in the OFF position:
•
there is battery voltage between terminals 4-8 and terminal 6- large chassis earth connector
(fixed power supply). If there is no voltage check that fuse 4 and its cable are in working
order.
