Transponder (TP) – IMMO ECU Communication
TP Read Protocol
(1) |
IMMO_ECU after IGN on(or CPU Reset cancellation) is sent
Challenge to TP and confirmed Serial Number and Signature.
|
(2) |
When response of input transponder is not correct, input
is retry.
|
(3) |
When response of input transponder is correct, The data
that calculate Encryption operation in the EEPROM program compared
with received data from TP.
When Codes is same, input is finished.
If the codes are not same, input are continued until when
codes are same.
|
(4) |
If IMMO_ECU EEPROM code is not programming, when correct
transponder is inputted (CRC Check OK), input is finished.
|
(5) |
After IGN1 on(CPU Reset cancellation), IMMO_ECU is reading
the maximum 5times Transponder Code
|
(6) |
In the IGN1 ON&EMS_state=Lock state, when received ANKNOWLEDGE,
