Hi mexanico1971
No data sheets. Just rough info, and part of my experience.

ST L9170: functions as a voltage regulator/ECU driver
99029 : heard that they are IGBT, and here injectors driver
ST L9122: Stepper motor driver, found that it is connected very similar to the more common device, ST L298 on 8Pxx, but with pins reallocated.
