INTRODUCTION - ELECTRICAL EQUIPMENT
WARNINGS
This vehicle is equipped with a starting system known as Smart-Key where the traditional ignition key has been replaced with an electronic key "T.E.G." (Transmitter for Entry and Go) combined with an electronic key reader and TEG-Reader radio frequency receiver.
Access to the vehicle through radiofrequency recognition of the remote control incorporated in the TEG is entirely the same as what takes place with the traditional remote control incorporated in the key fob.
The vehicle is not switched on/started up by inserting the key in the ignition switch (which is no longer present) and turning it but by inserting the TEG in the TEG Reader and activating the START/STOP button.
The distribution of the power supply to the vehicle (ignition-controlled INT, INT/A, AVV, etc.) is managed by the steering lock node and takes place in entirely the same way as for models equipped with a traditional key.
The following documentation often still uses the expressions Key ON, Key OFF, ignition-operated power supply (INT) or key to MAR, key to STOP, key to AVV. These must be interpreted in accordance with the following summary table:
| Key ON | TEG inserted in TEG Reader |
| Key OFF | TEG removed from TEG Reader |
| ignition controlled power supply (INT) | TEG inserted into TEG Reader |
| key on MAR | TEG inserted in TEG Reader |
| key on STOP | TEG removed from TEG Reader |
| key on AVV | TEG inserted and START/STOP button pressed |
PRECAUTIONS
Before working on the electrical system (connectors, electrical components, wiring etc.), always DISCONNECT THE BATTERY.
If the battery is disconnected the Steering Lock Node remains in the condition (unlocked or locked) that it is in: during workshop operations and repairs, whenever it is necessary to turn the steering wheel with the battery disconnected, leave the TEG inserted when the battery is disconnected. The steering will therefore remain released and free to turn.
INITIALISIATION PROCEEDURE FOR DOOR NODES
Following a power supply failure to the control units (for example, battery disconnection) the system must be initialized once again following the instructions below and working with the ignition key ON (TEG inserted) and the doors and windows closed.
- completely open the driver''s door window, keeping the operating button pressed for at least 3 seconds after the (lower) end of travel position
- completely close the driver''s door window, keeping the operating button pressed for at least 3 seconds after the (upper) end of travel position
- carry out the same operations for the passenger window
- make sure that the initialization is correct by checking that the windows work properly in automatic mode
