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 ?
