Hi Nomake,

Download the Hex Comm tool, send the commands manually and see what the ECU returns.

You need to set the tool to the correct baud rate and protocol, then send a hex command something like 78 12 34 00 to query the memory at location 1234. The response should be 3 bytes repeated over and over 1234xx1234xx where xx is the contents of the memory at address 1234.
send 12 00 00 00 to stop it.

Let me know what happens.

Also try the TCU, substitute 45 for 78 above.

Phil.
