Buenas noches. Su unidad de control solo debe realizarse a traves de UART. Porque no se puede escribir sobre CAN.

Thank you

[smart-prog]

Now you must remove SRS from car... and write backup via CPT! directly to CPU!

[Seven7i]

I already removed it

[Seven7i]

How i can do it

[AST_Support]

CPT H8SX UART connection.
