DIAGNOSIS FUNCTION
The diagnosis function makes the master warning light and the multi-information display turn on, and the cruise control indicator light does not blink as shown in the illustration. When a malfunction occurs in the dynamic radar cruise control system, the DTCs are stored in the driving support ECU.
| *1 | Master Warning Light | *2 | Multi-information Display |
| *3 | Cruise Control Indicator Light (Vehicle-to-vehicle distance control mode) |
*4 | Cruise Control Indicator Light (Constant speed control mode) |
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 fuses or the battery terminal, do not disconnect them until the inspection has been completed.
CHECK INDICATOR
| *1 | Master Warning Light |
| *2 | Multi-information Display |
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 combination meter assembly and the power management control ECU stores DTCs.
Note
When the system returns to normal, the "Check Cruise Control System" display in the combination meter assembly disappears.
Do not remove any fuses or disconnect any cables from the auxiliary battery terminals until the data stored in the ECUs is cleared.
