Mazda 3 problem
 

Hello,

have a mazda 3 singapore model. car delaying to start between 10-15 minutes before immobilizer or security light goes off. Immobilizer light keeps flashing code 23 before it goes off then the vehicle would start. any help with this problem is greatly appreciated.

I have tried replacing a new instrumental panel and brain box and reprogramming them but same problem.

I have checked the signal for the key and that is working fine.

P.S I am a trained automotive technician.
