Great!
Now I understand how UDS session works!I admire very much! I rewrited my code.The TesterPresent was disable.Thank you!

Hello Fabrice,

I updated my code:

TPUDSStatus result;
TPUDSMsg MsgUDS_WRITE = {};
TPUDSMsg MsgUDS_READ[2] = {};
TPUDSMsg MsgUDS_READ_TEMP = {};
DWORD count;

MsgUDS_WRITE.NETADDRINFO.SA = 0xFB;
MsgUDS_WRITE.NETADDRINFO.TA = 0x00;
MsgUDS_WRITE.NETADDRINFO.RA = 0x00;
MsgUDS_WRITE ...

Hello,

I did read that Post.

TPUDSStatus result;
TPUDSMsg MsgUDS_WRITE = {};
TPUDSMsg MsgUDS_READ[2] = {};
DWORD count;

MsgUDS_WRITE.NETADDRINFO.SA = 0xFB;
MsgUDS_WRITE.NETADDRINFO.TA = 0x00;
MsgUDS_WRITE.NETADDRINFO.RA = 0x00;
MsgUDS_WRITE.NETADDRINFO.PROTOCOL = PUDS_PROTOCOL_ISO_15765 ...

Hello,

In my case,the ECU's TesterPresent (0x3E) service is not standard.

Here is what I need:

But the PCAN UDS API does not match:

I want to disable the TesterPresent function,So I set to the default session:

TPUDSSessionInfo session;
result ...

PROBLEM SOLVED!!THANK YOU!!!

My Basic and TP API Version was outdated.Then I update the TP API and BASIC API to the latest version.The message is finally normal.

Again,thanks for your patience.Thank you very much!

I used the code you wrote.But the result is still the same,like yesterday.

Code:

void CUDSDlg::OnBnClickedButtonBoschTp()
{
TPCANTPMsg MsgTP_READ = {};
TPCANTPMsg MsgTP_WRITE = {};
TPCANTPStatus result;

MsgTP_WRITE.SA = 0xFA;
MsgTP_WRITE.TA = 0x00;
MsgTP ...

I add the function CANTP_AddMapping which returns code 0.And the function CANTP_Write returns code 0,too.

But the CAN message that the API acctually send is quite weird.Is there something wrong?

Another question,when the program runs to function CANTP_Uninitialize,it means ...

I think you just solve my problem perfectly! :lol: ;) Thank you!

Here is my code:

void CUDSDlg::OnBnClickedButtonBoschUds()
{
TPUDSMsg MsgUDS_READ = {};
TPUDSMsg MsgUDS_WRITE = {};
TPUDSStatus result;

MsgUDS_WRITE.LEN = 2;
MsgUDS_WRITE.DATA.RAW[0] = 0x10;
MsgUDS_WRITE.DATA.RAW[1] = 0x81 ...

Hello,

First all of,thank you it's so kind of you to answer my question. :)

I use the function UDS_SetValue,but UDS_Read still return error code 0x07.

Here's my code:

void CUDSDlg::OnBnClickedButtonBoschUds()
{
TPUDSMsg MsgUDS_READ;
TPUDSMsg MsgUDS_WRITE;
TPUDSStatus result;

MsgUDS_WRITE ...

Hello,

When I used PCAN-UDS TP API to send a request message to the ECU and try to read the respond message,the UDS_Read returned PUDS_ERROR_NO_MESSAGE.Actully,the ECU did respond with a POSITIVE_RESPOND_MESSAGE.

Here CAN Message screenshot:

Here's my code:
