ECU-Explorer allows you to read/write internal eeprom of Infineon 1797 type MCU

You can reset mileage , reset system time and edit ISN code (Secretkey).

To read Infineon MCU you need to open ECU aluminum case and connect BOOT-pin to the aluminum ECU case via resistor 0 - 1000 ohM .

You can reach boot-pin using two ways:

WARNING!!!! CONNECTION TO ECU MUST BE MADE STRICTLY AS PICTURED!!!!!! TAKE =12V POWER FROM PIN 1 ONLY!!!!!!! DON’T POWER ECU DIRECTLY FROM BATTERY OR POWER SOURCE!!!

1.

Safest way is to cut 15mm x 15mm rectangular window in aluminum case (As pictured.

2.

Less safe way:

Unscrew ECU case and carefully cut rubber seal by sharp knife, while heating work areas with hot air. Warning!!! Don’t let a knife to reach more than 5-9 мм inside ECU.

After rubber seal is finished to cut you must heat up upper cover (nearly connector) trying to lift it. You can pull cover firmly, screws will not allow circuit-board to bend.

After upper cover removed, you can reach boot pin. Boot pin must be grounded to the aluminum ECU case via 500 Ohm resistor.
