      2. Depress the brake pedal.

      3. The diagnostic mode is entered after the hazard warning lights flash.

        Tech Tips

        Confirm the factor that caused the engine to stop by checking the number of times the hazard warning lights flash.

    3. The diagnostic mode indicates the causes of the engine stop or failure to start by flashing the hazard warning lights as listed below.

      Engine Stop Factor
      Engine Stop Factor Number of Flashes Order of Priority
      No abnormal stop in the past 0 0
      Engine switch on (ACC or IG) 1 1
      Any door is unlocked 2 4
      Engine speed is too high or low 3 7
      Any door or engine hood is opened 5 2
      Shift lever is not in P 6 5
      Brake pedal is depressed 7 3
      Vehicle speed is abnormal 8 6
      Immobiliser collation discrepancy 9 9

      Tech Tips


      • When two or more of these conditions are responsible for the engine stop or failure to start, they will be indicated in the order of priority.

      • The remote engine starter ECU will store the code for the last engine stop factor in its memory, even after exiting the diagnostic mode. The code can not be cleared from the remote engine starter ECU.

      • The engine stop factor that flashes the hazard warning lights 4 times does not occur for this type of vehicle.
