   Chassis > Front Recognition Camera > Data List 

   Tester Display
   HV/EV Equipped Information

   HINT: 

   • When the specification stored by the forward recognition camera and the vehicle specification do not match, there is a malfunction in the specification information stored by the forward recognition camera. Therefore, replace the forward recognition camera.
   • When the specification stored by the forward recognition camera and the vehicle specification match, an ECM with different specifications may be installed. Therefore, replace the ECM.
