Wow. So I hear there is a radar in this unit and the 76GHz range is set aside for vehicle collision avoidance. Picture #3 in the post above appears to be a phased array antenna and if for 76GHz that would be very impressive. Not that long ago just this module would have cost more than the vehicle. In the 90s I worked in the radar cross section measuring business and was actually a human Guinee Pig for GM standing in front of a 76GHz imaging radar so they could profile a human for future research for vehicle avoidance systems. At that time I couldn't imagine something this sophisticated being provided in an everyday vehicle. Wow.Taking apart the acc module:
1. Remove the 4 outside screws and run a blade around the cover to cut through the silicon.
2. The cover comes off and exposes the radar antenna. Take those 4screws out and gently pry the board from the module. The backside has electronics, most likely fir the radar high frequency circuitry.
3. Remove the metal shielding cover, which exposes additional circuity and the 2 screws holding the camera in.
4. Remove the screws and the camera comes right out.
5. Now Iām stuck, still havenāt seen the eeprom. Suspect it behind this board. The board wonāt come out because the connector on the backside of module is soldered directly to this board. Iāll need to get desoldering wick to continueā¦.
