ECUHELP KT200 is a powerful ECU programmer capable of reading and writing Visteon DCU102 found in Ford and PSA vehicles.

A successful test was performed on a 2010 Citroën Jumper 2.2 HDi with a Visteon DCU-102 ECU using the KT200 in boot mode. The process required two unsoldered pins, similar to KTAG. The CNF pin is located next to the on/off switch of the bench cable.
📌 Note: Reading is only possible in boot mode, but OBD writing for Visteon DCU102 was also tested—worked flawlessly!

Firstly, please look at the ECU DCU102:

Next is to connect KT200 to Visteon DCU-102 boot mode.
Kit to use:
– Multifunction cable

To read and write, select the following driver in KT200:
→ TOOLS BOOT MODE
→ ST ST10Fxxx
→ ST10F273 / ST10F275 / ST10F276 *K
or
→ ST10F273 / ST10F275 / ST10F276 *CAN

Alternatively, read via RX TX protocol:
Kit to use:
-Multifunction cable
– Transistor PNP 2N3906

To read and write use the following driver:
→ TOOLS BOOT MODE
→ ST ST10Fxxx
→ ST10F273 / ST10F275 / ST10F276 *RxTx

Conclusion:
With ECUHELP KT200, read and write the Visteon DCU102 is easier, whether in boot mode or using RX/TX protocol. For OBD writing, KT200 has been tested successfully too, making it a reliable tool for ECU programming.
