939010994 - ENGINE IGNITION - GENERAL REMARKS

WARNINGS

This vehicle is equipped with a starting system known as Smart-Key, whereby 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.
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 rather by inserting the TEG into the TEG Reader and activating the START/STOP button.Access to the vehicle through radiofrequency recognition of the remote control incorporated into the TEG is entirely the same as what takes place with the traditional remote control built into the key fob.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 according to the following summary table:
Key ONTEG inserted in TEG Reader
Key OFFTEG removed from TEG Reader
ignition controlled power supply (INT)TEG inserted into TEG Reader
key on MARTEG inserted in TEG Reader
key on STOPTEG removed from TEG Reader
key on AVVTEG inserted and START/STOP button pressed
To prevent serious damage to the electrical and electronic components, never try and start the engine with the battery earth lead slack.Never pull the leads or wiring using force because this would result in the cables being disconnected from the connectors or terminals.Disconnect all the control units and electronic devices when carrying out arc welding operations on the bodyshell.Before replacing a fuse, check that the circuit protected is not faulty.When replacing fuses, make sure that the new fuse is the correct amperage. Do not use fuses that have a higher or lower amperage than required.

PRECAUTIONS

Take care with high voltages. The electronic ignition system produces voltages of 20,000V and more, which could be very dangerous. Take great care when working on or near these components.

When working on electrical components, always follow very carefully the precautions described below:

  • Remove rings, wrist watches and other metal objects.
  • Prevent fire risks. Do not smoke when working close to the battery or components which get hot during use (e.g. halogen bulbs), nor in the area of the engine compartment when the engine is still hot.
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.
