DYNAMIC RADAR CRUISE CONTROL SYSTEM DIAGNOSIS SYSTEM


  1. DIAGNOSIS FUNCTION


    1. The diagnosis function makes the master warning light and the multi-information display turn on. When a malfunction occurs in the dynamic radar cruise control system, the DTCs are stored in the driving support ECU.

      Note


      • The master warning light turns off if the system returns to a normal condition.

      • Since the stored data in the driving support ECU is erased by disconnecting the EFI and ETCS fuses or the battery terminal, do not disconnect them until the inspection has been completed.

  2. CHECK INDICATOR


    1. A01GK0CE01

      When a malfunction occurs in the dynamic radar cruise control system, the system turns off the cruise control indicator and the master warning light illuminates at the same time a "pong" sound is heard. Also, "Check Cruise Control System" is displayed in the No. 1 meter ECU sub-assembly and the ECM stores DTCs.

      Tech Tips


      • When the system returns to normal, the "Check Cruise Control System" display in the No. 1 meter ECU sub-assembly disappears.

      • Do not remove any fuses or disconnect any cables from the battery terminals until the data stored in the ECUs is cleared.
