Immobiliser - PIAGGIO Liberty 125 Workshop Manual

Liberty 125 - 200 4tempi

Immobiliser

The electric ignition system is fed with direct cur-
rent and is protected by an antitheft immobilizer
integrated to the control unit.
The ignition system consists of:
- electronic control unit
- immobilizer aerial
- master and service keys with built-in transponder
- H.V. coil
- diagnosis LED
The diagnosis LED also works as a blinking light
to deter theft. This function is activated every time
the key switch is set to «OFF», when the side
stand is lowered or the engine emergency cut-off
switch is set to «OFF». It remains activated for 48
hours in order not to affect the battery charge.
When the ignition switch is turned to «ON», the
deterring blinker function is deactivated. Subse-
quently, a flash confirms the switching to « ON».
The duration of the flash depends on the electronic
control unit program (see figure).
Whenever the LED is off and remains so, even
when switching it to «ON», it is necessary to check
if:
- the battery is charged
- 15A main fuse is working correctly.
Connect the immobilizer tester to the diagnosis
socket (see ET4 125 manual) located behind the
front left fuse box flap.
If the serial LED remains off, check the electronic
control unit supply as follows:
