Ignition problems

[Luchmun]

Hi,

I have a Honda Vezel grade Z. The car was fine and suddenly lots of dash panel light appears in the dash board. I have checked the vehicle to a Honda dealer and the problems were resolved.

The next day, the same problems reappeared and the car shut down completely. I was disappointed with the local Honda dealer.So I decide to buy an HDS and diagnosed the car myself.

I noticed that there was problem with the immobilizer system. I changed the smart power control unit, still the start stop button do not start any ignitions. I checked all the fuses and seemed in good conditions. I changed the power button, same result as before. Does anyone knows about this problems ?

12V battery replaced or still original one?

what was the error code with imobilizer system? you should not just swap immobilizer control units. There is software with seedkey inside which is identical to the vehicle. your vehicle will not start  unless the authentication of the immobilizer system with smart key is successful.
