bad Suzuki SAS (Steering Angle Sensor) IC identification

(1/2) > >>

I have a broken Suzuki SAS (Steering Angle Sensor) that I am trying to fix, and there are a few ICs I had no luck identifying, I tried to google them and search various websites without luck.
I am trying to find the datasheets of those ICs.
any help provided is appreciated

Tim S:
IR is International Rectifier, now part of Infineon Technologies. Not familiar with the device, but I wouldn't hold much hope. You may be better looking on auction sites for a good used one.

same here, automaker(s) love to have their own proprietary chip(s)

better go to a scrap yard ...

the IR  logo  is not International Rectifier

the ic markings look like laser engraved,  could be hidden known brand  ???

better post on Suzuki forums than here

They love off the shelf parts relabeled with their own part number.

that is so anti-repair and sucks, I wasted hours trying to fix the sensor.
I tried to search in a scrap yard and found a similar one, but the car did not accept it when I looked into the CAN messages the message ID between the sensors was different,
the old one is 0x119 and the new one is 0x115, and I have no clue how to code the ESP or the ECM to look into the other sensor message ID, or how to change the other sensor ID to 0x119.
The dealership is asking for crazy prices, they've quoted me 1/4 of the car price just for getting a new sensor and installing it.
