KT200II wiring diagram of MARELLI 9DF – Fiat, Alfa Romeo, Lancia [Diesel]:
To connect to the control unit use:
– Multifunction cable
On the latest Marelli 9DF HW001 / HW002 or with recent software updates, KT200II still allows the ECU’s Micro + EEPROM to be read, but the reading time of the Micro is extended considerably.
It is also possible to write the microprocessor file on the bench.
It is possible to write the EEPROM only in JTAG.
If you want to write the ECU to the car instead, use the OBD driver, but you have to check if the FCA Secure GateWay (SGW) system is present.
Many of the FCA MY 2018 models are adopted of a security control unit: the gateway device “SGW” (SECURE GATE WAY).
It’s located within the CAN network and communicates in an encrypted mode.
If you are working on an FCA model from 2018 the reading may therefore not be allowed.
To remedy this, proceed as follows:
Turn off the switchboard and wait for the delayed power shutdown (power latch)
Locate the SGW control box usually mounted near the steering column. In some cases it is necessary to remove the under steering wheel housing for better access.
Disconnect the two connectors A and B of the SGW control unit.
Connect the Y-cable and plug it directly into the two connectors. The Y-adapter cable for the SGW bypass can be found commercially.
Connect the KT200II via the orange OBD cable and you can now read and write the ECU.
If you don’t have the bypass Y-cable, you can connect directly with needles on the CAN H and CAN L wires behind the ECU connector connected to the vehicle harness using the multifunction cable. For +12V and ground connect directly to the battery of the car.
When finished, switch off the switchboard and wait for the delayed power supply (power latch) to switch off and reset the SGW system.
