Manual Configuration

Reprogramming is also possible without CANoe. In this case, the following CAN Messages

(UDS/ TP) must be sent on the diagnostic CAN (CAN0) manually:

CAN-Identifier:

Tester --> VC-EVCC, Request: 0x610

VC-EVCC --> Tester, Response: 0x612

Tester --> Functional: 0x614

1. Extended Session:

Request: 02 10 03 FF FF FF FF FF

Response: 06 50 03 00 32 01 F4 FF

2. Tester Present:

Response: 02 7E 00 FF FF FF FF FF

Caution

The message “Tester Present” has to be sent cyclically in order to keep the VC-EVCC

in the extended session, e.g. every second. Otherwise the extended session will be

terminated after approximately 4 – 5 seconds.
