ELECTRICAL
SYSTEM
Programming TEGs in the NTR memory
After receiving the new electronic keys (TEGs) from Fiat Ricambi, make sure you have all the customer's old
electronic keys (TEGs).
Connect the instrument to the car's diagnostic socket and proceed as follows.
1. Connect the instrument to the car's diagnostic socket.
2. Set the electronic key reader (NTR) to 'Programming' mode.
3. Insert all the electronic keys (TEGs) in sequence in the electronic key reader (NTR).
4. Shut down 'Programming' mode.
All electronic keys (TEGs) not presented during this step will not be deleted and cannot be stored again
at a later time.
5. Check that the system is working properly before delivery to the customer by using all the electronic keys
(TEGs) to start the engine and lock/unlock the doors with the remote control.
NOTE: Only use spare parts to deal with functional anomalies. Never exchange remote control electronics between
electronic key (TEG) systems: this may compromise future servicing of the car.

9.2.6 Procedures for replacing components

Replacing the electronic key reader (NTR)
Ask the customer for all the electronic keys (TEGs) in their hands.
The customer must also be asked to demonstrate that the car is actually theirs by presenting the car's logbook and a
valid form of identification.
Connect to Fiat Ricambi using the personal computer provided. Enter the chassis number, the model code and use a
depannage order to request a new NTR (by entering the part number to identify the version). Specify the number
required.
Proceed as follows after receiving the new NTR from Fiat Ricambi:
1. Check that the serial number printed on the label applied to the order coupon corresponds to that on the NTR.
2. Check that the chassis number printed on the label applied to the order coupon corresponds to car's.
3. Install the NTR if all codes correspond.
4. Store all TEGs owned by the customer in the NTR.
5. All TEGs which are not included in the procedure will be eliminated from the NTR and cannot be stored again.
6. Check that the system is working properly before delivery to the customer by using all the TEGs to start the
engine and lock/unlock the doors with the remote control.
Replacing the engine control ECU
Install a new engine control ECU and insert a TEG in the NTR to start the self-programming procedure.
Press the start/stop button with the brake/clutch pedal pressed to start the engine. Check that the engine is running
properly.
Replacing the electrical steering lock (NBS)
Install a new NBS and insert a TEG in the NTR to start the self-programming procedure.
Remove the TEG from the NTR after 10 seconds and wait for the mechanical steering lock to be applied (after
approximately 5 seconds).
Check that the steering wheel is locked.
Replacing the body computer (NBC)
Install a new body computer and insert a TEG in the NTR to start the code alignment procedure.
Press the start/stop button with the brake/clutch pedal pressed to start the engine. Check that the electrical system is
running properly.
Replacing lock barrels and/or emergency mechanical key
Connect to Fiat Ricambi using the personal computer provided. Enter the chassis number, the model code and use a
depannage order to request a new electronic key and barrel kit (by entering the part number) according to vehicle
type and outfit.
NOTE: One only barrel cannot be ordered by providing the mechanical code only.
IMPORTANT: The mechanical code of the emergency key and the electronic code of the electronic key (TEG) are
matched when the vehicle is programmed for the first time at the end of the line and must not be separated for any
reason.
