Remove chip. Read it that way. I use GQ-4x.

Desoldering is the most reliable way. Other methods are/can be hit or miss.

24C02 and other I2C similar serial eeproms are really tricky to read or write in circuit (ICSP). The main problem is it master-slave configuration and it bus timing associated for read and writing procedures. The best result until now, is desolder, work on it and re-solder.

with clip you may read it 10 times and you will get at least 3 different versions....

I'm reading and writing a 24c02 in circuit in an Alfa Romeo Bosch M2.10.x ECUs, using a Willem eprom without any problems. I guess it depends on the electronic design whether you can read it in circuit or not.

In my M3.2 ecu I was not able to read on the board, unsoldering did the trick. Also with Willem programmer.

I tried to use the car prog to read it in on the board I also tried probing it using a willem programmer. I didn't have success so I removed it and tried to read. Not having luck yet. ( Having problems with posting this)
