Immobilizer fault: aerial not working (open or short-circuited)
Error cause
•
An electric interruption or a ground short circuit or voltage to the circuit have been detected
Troubleshooting
•
Check the sensor connector on the cable harness and the instrument panel connector. If
not OK, restore; if OK, check electrical characteristics and aerial circuit continuity from the
instrument panel connector on PIN 24 and 34: if not OK, restore cable harness; if OK, check
circuit ground insulation: if not ground insulated, restore cable harness; if insulated, with key
ON, with instrument panel connector disconnected, check that there is not voltage at the
circuit ends: if there is voltage, restore the cable harness

In case of doubts in operation of the engine revs indication, it is possible to connect the vehicle to the
diagnosis instrument and activate the engine revs indication choosing the function "Rpm indicator" from
the "Devices Activation" screen page (injector icon)
Installing a new instrument panel
In case the instrument panel is replaced by a new one, follow the procedure shown below so that the
immobilizer system (key storage) and the exhaust butterfly valve (controlled by the ECU through the
instrument panel) operate correctly.
1. Request all the keys of the vehicle in the customer possession.
Once the instrument panel is electrically connected to the vehicle and a key is set to ON, the key is
stored and the instrument panel waits for 20 seconds for a possible second key. If there is a second
key, remove the first key and wait for the storage of the second key. When the second key storage is
complete, the instrument panel waits for another key up to a maximum of 4 total keys or the procedure
will be interrupted after 20 seconds.
At this stage, the instrument panel turns on as usual.
2. Deleting the errors stored by the instrument panel: select Menu and then Diagnosis. An access code
is required to enter this menu:
12412
Then, select the option: "Delete errors"
