Troubleshooting VCM MemoKey

make the key storage via Teleservice, the procedure does not terminate correctly:
1) Be sure you are using the correct keys kit ( 2 Keys + ide 1+ide2 + pin source+ meccanical code).
For this operation can not be used the keys parts.
Be careful not to use the keys of range € 3
Be careful not to use the keys without transponders (only mechanical)
If point 1 has been complied
You should read the memory faults in the VCM and check if have present errors :

CASE: PROBLEMS OF ANTENNA
CASE: YOU ARE USING THE KEYS PARTS (WRONG KEYS)
CASE: YOU ARE USING BETWEEN TWO KEYS mixed KIT
CASE: YOU ARE USING THE KEYS ALREADY STORED ON ANOTHER VCM
CASE: YOU ARE USING THE KEYS WHITOUT TRASPONDER (MECHANICAL)

We have 6 situation where FAILS THE PROCESS FOR PROGRAMMING KEYS:

Storing keys BY Teleservice, it is VERY IMPORTANT TO GO TO CONSULT THE READING FAULT MEMORY OF ECU VCM.
That because, when the procedure for storing keys does not end correctly, the VCM gives us always at least 2 Faults:
1 PRESENTE
1 INTERMITTENTE
The fault present, will always make refers to the fact that the VCM has not yet get any key (PLANT MODE).
The Intermittent Fault instead, it will be essential to understand why the storage
procedure fails.

VCM Troubleshooting Memory keys by teleservices

WITH ALREADY 2 KEYS STORED

THE VCM inside it has already stored the keys, so it is only possible to add keys via easy by stand-alone

OF ANTENNA

Error during memory keys

B7 FMI: 02 indicates that the VCM is IN THE STATE IN WHICH IT IS NOT 'STILL ABLE TO GET THE STORAGE OF 2 KEYS.

The DTC: B9 FMI: 07 shows a hardware problem es: antenna defective, not correctly positioned or one of the two pins unconnected in VCM X1, CHECK THE RESISTANCE OF ANTENNA (9.9 hom APPROXIMATELY between pin X1-1 and X1-3 of the VCM.

2 CASE: PROBLEMS OF ANTENNA

ARE USING THE KEYS PARTS (WRONG KEYS)

The correct procedure, requires the use of keys with different ide, pin source the same for both keys

Error during memory keys

B7 FMI: 02 indicates that the VCM is IN THE STATE IN WHICH IT IS NOT 'STILL ABLE TO GET THE STORAGE OF 2 KEYS.

The DTC: FMI B4: 0C indicates that PIN THE SOURCE OF THE TWO KEY AND 'DIFFERENT or equal to 0, There is not inside of the keys. In fact we were using parts of the keys (3 keys) that does not have inside source your PIN

3 CASE: YOU ARE USING THE KEYS PARTS (WRONG KEYS)

In practice, I'm using the wrong keys

ARE USING BETWEEN TWO KEYS mixed KIT

The correct procedure, requires the use of keys with different ide pin and source the same for both keys

Error during memory keys

B7 FMI: 02 indicates that the VCM is IN THE STATE IN WHICH IT IS NOT 'STILL ABLE TO GET THE STORAGE OF 2 KEYS.

The DTC: FMI B4: 0C indicates that PIN THE SOURCE OF THE TWO KEY AND 'DIFFERENT or equal to 0, There is not inside of the keys
In our case we were USING THE KEYS FROM TWO DIFFERENT KIT, therefore with two DIFFERENT PINSOURCE between a key and the other.

4 CASE: YOU ARE USING BETWEEN TWO KEYS mixed KIT

ARE USING THE KEYS ALREADY STORED ON ANOTHER VCM

The correct procedure, requires the use of keys with different ide pin and source the same for both keys

Error during memory keys

B7 FMI: 02 indicates that the VCM is IN THE STATE IN WHICH IT IS NOT 'STILL ABLE TO LEARNING THE STORAGE OF 2 KEYS.

The DTC: B9 FMI: 0C indicates that the VCM receives no response from the transponder. This could be: Key with transponder defective Keys already stored on another VCM

5 CASE: YOU ARE USING THE KEYS ALREADY STORED ON ANOTHER VCM

ARE USING THE KEYS WHITOUT TRASPONDER (MECHANICAL)

The correct procedure, requires the use of keys with different ide pin and source the same for both keys
