Diagnostic Code - 3 Flashes - APRILIA SR MAX 125 ie Service Station Manual

Electrical system
Electric characteristic
immobilizer aerial
~ 7 ÷ 9 Ohm
2-FLASH CODE - Example with programmed control unit, no transponder and/or malfunctioning aerial.
Ignition disabled-Vehicle immobilised

Diagnostic code - 3 flashes

If the 3-flash code is detected, check if the failure occurs when the MASTER key in inserted into the
key switch.
- If the failure disappears when the MASTER key is used, proceed with coding a new service key (Blue).
- If the failure persists, it means that the MASTER key and the decoder are not linked; in this case,
replace the decoder and then encode the keys.
The immobilizer system is efficient when, after switching over to «ON», only a 0.7-sec flash is detected
(see diagram).
In this case, the engine can be started.
Example with programmed decoder, transponder, programmed key and working aerial. The ignition
is enabled (regular use conditions)
3-FLASH CODE - Example with programmed decoder, aerial working properly and unknown trans-
ponder code. Ignition disabled-Vehicle immobilised
