9.2.3 Diagnostic Codes
After the flash that denotes the switching to the «ON» status, the system may output a
number of malfunction codes.
The LED stays initially off for 2 seconds, and then the diagnostic codes are displayed in the
form of 0.5-second flashes.
Once the malfunction code has been displayed, the LED turns on to indicate that ignition is
impossible (see graph below).
2-Flash code
Example – electronic control unit program-
med, transponder absent and/or antenna
malfunctioning.
Ignition disabled – Vehicle immobilized
3-Flash code
Example - electronic control unit program-
med, aerial in working conditions and
transponder code unknown.
Ignition disabled – Vehicle immobilized
1 = LED on
2 = LED off
3 = LED remains lit
9.2.4 2-Flash Diagnostic Code
If the 2-flash diagnostic code is displayed, check if the malfunction persists when the key
(including the MASTER key) is changed. If the anomaly persists with any key, detach the
control unit aerial connector and check the continuity of the antenna by using the
recommended multimeter 020331Y.
Standard resistance:
Immobilizer antenna ~ 7-9 O
If the value is not as specified, replace the antenna.
If no anomaly is found, replace the control unit.
Warning – Before performing the storing procedure on the new control unit, check that no
malfunction code is signaled. This is precaution is needed to avoid wasting a new control
unit.
