Problem: When I was using Yanhua Digimaster 3 to read the 93C66 chip, the msg was "(1EOF) Not find device". It's a 2013 Camry Hybrid. What's the reason? Please guide me.
Solution
The reason why cause issue is because of clamp loose connection.
1. Re-clamp the connection.
2. Or remove the 93C66 chip to solder on the OBP adapter for reading.
