Today, one customer meet a issue below:

One user feedback: I have KTM Bench ECU programmer to test with different ecms

And always with the same message "Bosch MEDC17 (TC1724 /1728 / 1767 / 1782 / 1784 / 1797) Flash identification, entering reprogramming mode failure"

I have tested the same connection with another j2534 interface

And can connect with ecm obviously cant read

the ecu type is 1766.

Attach several images of the Bosch ECU type & its internal pcb, the connection diagram, the error messages:

obdexpress.co.uk engineer solution:

The cpu is tc1767,but you connect as tc1766,so your connection is wrong.

Finally, the problem is solved!

Here BOSCH MEV17.4.2 IROM TC1767 PSA 1033:

PLUGIN 286

DIRECT CONNECTION WITH TRASDATA SYSTEM

In order to perform the Trasdata direct connection with free wirings it will be necessary to

connect the POL4 pin and DSDO signal too. DSDO is the yellow wire on BDM connector of the

universal adapter F34TD003.

DIRECT CONNECTION WITH NEWGWNIUS SYSTEM

In order to perform the NewGenius free wires connection you need the F32GN037

or F32GN037-B cable. BLUE wire = CNF1, GREY wire = BOOT

DIRECT CONNECTION

DIMA CONNECTION

Connect the 2 boot pin to the programming lay-by pin n. 10. Moreover it is necessary to

solder a third wire that must be connected to the CNF1 clamp on the DIMA.
