Renault / Bosch / MS15.5 - DTI
Bosch ECU used to control Renault 1.9 DTI engines. The immobilizer code is stored in I2C
Bus memory (24C02).
1. Read 24C02 memory contents (256 Byte).
2. Locate the immobilizer code sequence – see picture below. Although the immo entry
address is not constant, it is easy to find using this calculation method:
( $0B $04 + $F4 $FB = $FF $FF ).

3. Modify the memory contents – see picture below ( $00 $00 + $FF $FF = $FF $FF ).
4. Programm the I2C memory. The immobilizer entry is cleared now but the ECU can
not work without valid immobilizer module signal.
