Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - CRUISE CONTROL
DYNAMIC RADAR CRUISE CONTROL SYSTEM - FAIL-SAFE CHART
| Constant speed control mode and vehicle-to-vehicle distance control mode: |
If the following conditions are detected while the dynamic radar cruise control system is in operation, the system clears the stored vehicle speed in the ECM and cancels the dynamic radar cruise control operation.
| *1 | Master Warning Light |
| *2 | Cruise Control Indicator Light (Constant Speed Control Mode) |
| *3 | Multi-information Display |
| *4 | Cruise Control Indicator Light (Vehicle-to-vehicle Distance Control Mode) |
| Vehicle Condition | Auto Cancel Condition | Fail-safe Deactivation Condition |
Cruise control indicator light turns off Master warning light comes on "CHECK CRUISE CONTROL SYSTEM" is displayed "Pong" warning sound is heard | There is an open or short in the stop light switch circuit There is a problem with the vehicle speed signal | Turn the cruise control main switch on again |
| Constant speed control mode and vehicle-to-vehicle distance control mode: |
If the following conditions are detected while the dynamic radar cruise control system is in operation, the system clears the stored vehicle speed in the ECM and prohibits the dynamic radar cruise control operation.
| Vehicle Condition | Auto Cancel Condition | Fail-safe Deactivation Condition |
| Cruise control indicator light turns off | There is a problem with the throttle position sensor and the motor | Turn the cruise control main switch on again |
| Constant speed control mode and vehicle-to-vehicle distance control mode: |
If the following conditions are detected while the dynamic radar cruise control system is in operation, the system clears the stored vehicle speed in the ECM and cancels the dynamic radar cruise control operation.
| *1 | Master Warning Light |
| *2 | Cruise Control Indicator Light (Constant Speed Control Mode) |
| *3 | Multi-information Display |
| *4 | Cruise Control Indicator Light (Vehicle-to-vehicle Distance Control Mode) |
| Vehicle Condition | Auto Cancel Condition | Fail-safe Deactivation Condition |
Cruise control indicator light turns off Master warning light comes on "CHECK CRUISE CONTROL SYSTEM" is displayed "Pong" warning sound is heard | There is a problem with the stop light switch input circuit There is a problem with the cancel circuit | Turn the engine switch off |
| Vehicle-to-vehicle distance control mode: |
If the following conditions are detected while the dynamic radar cruise control system is in operation, the system clears the stored vehicle speed in the ECM and cancels the dynamic radar cruise control operation.
| *1 | Master Warning Light |
| *2 | Cruise Control Indicator Light (Constant Speed Control Mode) |
| *3 | Multi-information Display |
| *4 | Cruise Control Indicator Light (Vehicle-to-vehicle Distance Control Mode) |
| Vehicle Condition | Auto Cancel Condition | Fail-safe Deactivation Condition |
Cruise control indicator light (vehicle-to-vehicle distance control mode) turns off Master warning light comes on "CHECK CRUISE CONTROL SYSTEM" is displayed "Pong" warning sound is heard | There is a problem with the millimeter wave radar sensor The beam axis of the millimeter wave radar sensor deviates There is a problem with the radar cruise control system | Turn the engine switch on (IG) |
| Vehicle-to-vehicle distance control mode: |
If the following conditions are detected while the dynamic radar cruise control system is in operation, the system maintains the stored vehicle speed in the ECM and cancels the dynamic radar cruise control operation.
| *1 | Master Warning Light |
| *2 | Cruise Control Indicator Light (Vehicle-to-vehicle Distance Control Mode) |
| *3 | Multi-information Display |
| Vehicle Condition | Auto Cancel Condition | Fail-safe Deactivation Condition |
Cruise control indicator light (vehicle-to-vehicle distance control mode) turns off Master warning light comes on "CLEAN RADAR SENSOR" is displayed "Pong" warning sound is heard | There is dirt on the millimeter wave radar sensor.
| Recover from the condition on left (RESUME operation is possible after recovery) |
| Vehicle-to-vehicle distance control mode: |
If the following conditions are detected while the dynamic radar cruise control system is in operation, the system maintains the stored vehicle speed in the ECM and cancels the dynamic radar cruise control operation.
| *1 | Master Warning Light |
| *2 | Cruise Control Indicator Light (Vehicle-to-vehicle Distance Control Mode) |
| *3 | Multi-information Display |
| Vehicle Condition | Auto Cancel Condition | Fail-safe Deactivation Condition |
Cruise control indicator light (vehicle-to-vehicle distance control mode) turns off Master warning light comes on "CRUISE CONTROL NOT AVAILABLE" is displayed "Pong" warning sound is heard | The wiper switch is in HI position The ECT 2nd Start switch is on | Recover from the condition on left (RESUME operation is possible after recovery) |
| Constant speed control mode: |
If the actual vehicle speed is 16 km/h (10 mph) less than the set vehicle speed while the dynamic radar cruise control system is in operation, the system clears the stored vehicle speed in the ECM and cancels the dynamic radar cruise control operation, as the load on the vehicle may be excessive or the set vehicle speed may be set too high.
| Constant speed control mode and vehicle-to-vehicle distance control mode: |
If the actual vehicle speed drops below the low speed limit (approximately 50 km/h [30 mph]) while the dynamic radar cruise control system is in operation, the system maintains the stored vehicle speed in the ECM when in vehicle-to-vehicle distance control mode and clears the stored vehicle speed in the ECM when in constant speed control mode and cancels the dynamic radar cruise control operation.
| Constant speed control mode and vehicle-to-vehicle distance control mode: |
If the VSC system operates or a cancel request is received from the 4WD system while the dynamic radar cruise control system is in operation, the system maintains the stored vehicle speed in the ECM and cancels the dynamic radar cruise control operation.
