DIAGNOSIS FUNCTION
The diagnosis function makes the master warning light and multi-information display turn on and the cruise control indicator light and SET indicator light turn off as shown in the illustration. When a malfunction occurs in the dynamic radar cruise control system, DTCs are stored in the ECM.
| *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) |
| *5 | SET Indicator Light | - | - |
Note
The MASTER warning light turns off if the system returns to normal.
CHECK INDICATOR
Turn the ignition switch to ON.
Check that the cruise control indicator light and RADAR READY indicator turn on when the cruise control switch is pushed on and that the indicator light turns off when the cruise control switch is pushed off.
Tech Tips
If the cruise control indicator light check result indicates a problem, proceed to troubleshooting for the combination meter assembly section.
If a malfunction occurs in the vehicle speed sensors, stop light switch assembly or other related parts during cruise control driving, the ECM activates the AUTO CANCEL function of cruise control and goes off the cruise control indicator light. At the same time, the malfunction is stored as a diagnostic trouble code.
