Electrical system
After the failure code indication, a steadily on LED signals that ignition is disabled; see the table:
Diagnostic code - 2 flashes
When the 2-flash code is detected, carry out the following checks:
- Check if the failure continues after changing key (MASTER key included). If the failure persists with
any key, disconnect the aerial connector from the control unit and check the aerial for continuity with
the recommended tool.
If non-conforming values are measured, replace the aerial.
If no failures are found in the aerial, replace the control unit.
CAUTION
BEFORE PROGRAMMING THE NEW ELECTRONIC CONTROL UNIT CHECK THAT NO FAILURE
CODE IS INDICATED. THIS IS NECESSARY TO AVOID SPOILING A NEW CONTROL UNIT
Specific tooling
020331Y Digital multimeter
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 control unit are not linked; in this case,
replace the control unit 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.
