In case the LED turns off and remains so even
when switching over to « ON », 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, proceed to check the
control unit supply as follows:
- Disconnect the control unit connector and check
if:
- There is battery voltage between terminal 8 (Red/
Blue) and the ground lead.
- There is battery voltage between the terminal 8
(Red/Blue) and the terminal 12 (Black) as shown
in the figure
- there is battery voltage between terminals 9 and
12 with the key switch in «ON».
If no faults are found, replace the control unit.

and SERVICE (Blue) keys as follows:
- Insert the MASTER key, turn it to "ON" and keep
it in that position for 2 seconds (limit values: 1 ÷ 3
