3.2. Dealer key preparation function ‘Make Dealer TP’
This function is used for new (unlocked) key preparation for registration by dealer-level equipment: VAS
or VCDS.
1)
Dismount Kessy unit, unplug connectors and take out internal board from its casing.
2)
Plug clip-connector cable into Kessy Prog device.
3)
Clean EEPROM chip pins on Kessy unit board.
4)
Plug clip-connector to EEPROM chip as shown on pic.3.
5)
Please pay attention
:
red wire on clip-connector must be linked up with first pin on 93c86 chip.
6)
Launch ‘Make Dealer TP’ function from onscreen menu.
If Kessy unit memory reading performed successfully you will see such message on LCD:
“Reading OK”.
If electrical contact between clip-connector and 93c86 chip is bad you will see message “Waiting EEP
Press a key to cancel” on LCD. When normal contact will be restored another message appears: “Reading
OK”. Also you can cancel the operation by pressing ‘Enter’ or ‘Return’ button.
If Kessy unit memory reading was unsuccessful message “Reading Error” occurs on LCD. In this case
press ‘Enter’ button to return to menu.
7)
After successful reading and “Reading OK” message press ‘Enter’ button. You will see message “New
Project?” If ‘Enter’ button is pressed EEPROM memory of Kessy unit will be stored in device’s internal
memory. You should do it only at first time you connect to certain Kessy unit. In case of later connection
(for second and so on key registration) press ‘Return’ when you see “New Project?” message on LCD. In
this case current Kessy unit memory content will be transferred to device’s RAM, and ROM will hold
EEPROM initial state. This is important for recovery after any programming error.
8)
Now Kessy Prog analyses software version and number of registered keys. This data will be displayed on
LCD (pic.4).
If Kessy unit has SW version 22, 23, 24 (Kessy Continental) – algorithm 3, you will see message
“Connect the power connector then press OK”. It is necessary to plug crocodile connector cable as shown on
picture 5 and press ‘Enter’ button.
9)
While Kessy Prog is reading unit memory you will see message “Reading EEP…” After the process is
complete key position selection menu will appear (pic.6). Set position number with mini-joystick and
confirm selection with “
┘
” symbol.
Maximum number of registered key is 8, so the position number must be equal or less than 8. New key
may be registered on empty or already used position.
10)
As soon as you have set key position number, message “Waiting inverter startup…” appears and then
“Take TP or cancel”.
11)
Bring new key or chip onto Kessy Prog device as shown on pic.7.
If key or chip reading is successful its type and state will be displayed on LCD (pic.8, 9, 10).
