Notes:
|
|
- default timeout of 100ms on manual requests is insufficient
|
|
- initial fields padding includes the UDS/OBD response header,
|
|
i.e. 2 bytes for a type 21 request / 3 bytes for type 22
|
|
- CAN bus being switched off by the vehicle can be detected via CAN status turning error-passive
|
|
|
|
Manual request examples:
|
|
- obd can1 req dev -t1000 7e4 7ec 2101
|
|
- obd can1 req dev -t1000 7e4 7ec 2105
|
|
- obd can1 req dev -t1000 7e4 7ec 22b002
