Road Test
ROAD TEST1. PROBLEM SYMPTOM CONFIRMATION
HINT: The dynamic laser cruise control system has two cruise control modes: the constant speed control mode and vehicle-to-vehicle distance control mode.
- The vehicle-to-vehicle distance control mode is always selected when starting up the dynamic laser cruise control system.
- Operation of the constant speed control mode is the same as that for a conventional cruise control system.
a. Inspect the SET function.
1. Turn the main switch ON.
2. Drive at the required speed (43 km/h (27 mph) or higher).
3. Push the cruise control main switch to -/SET.
4. After releasing the switch, check that the vehicle cruises at the set speed.
b. Inspect the + (ACCELERATION) function.
1. Turn the main switch ON.
2. Drive at the required speed (43 km/h (27 mph) or higher).
3. Push the cruise control main switch to -/SET.
4. Check that vehicle speed increases while the cruise control main switch is pushed to +/RES, and that the vehicle cruises at the newly set speed when the switch is released.
5. Momentarily push the cruise control main switch +/RES and then immediately release it. Check that vehicle speed increases* (tap-up control).
HINT: *: Constant speed control mode: increases by 1.6 km/h (1.0 mph); vehicle-to-vehicle distance control mode: increases by 5 km/h (CANADA) or 5 mph (USA).
c. Inspect the - (COAST) function.
1. Turn the main switch ON.
2. Drive at the required speed (43 km/h (27 mph) or higher).
3. Push the cruise control main switch to -/SET.
4. Check that vehicle speed decreases while the cruise control main switch is pushed to -/SET, and the vehicle cruises at the newly set speed when the switch is released.
5. Momentarily push the cruise control main switch to -/SET, and then immediately release it. Check that vehicle speed decreases* (tap-down control).
HINT: *: Constant speed control mode: decreases by 1.6 km/h (1.0 mph); vehicle-to-vehicle distance control mode: decreases by 5 km/h (CANADA) or 5 mph (USA).
d. Inspect the CANCEL function.
1. Turn the main switch ON.
2. Drive at the required speed (43 km/h (27 mph) or higher).
3. Push the cruise control main switch to -/SET.
4. When performing one of the following, check that the cruise control system is cancelled and that the normal driving mode is reset.
- Depressing the brake pedal
- Moving the shift lever to any position except D
- Turning the main switch OFF
- Pulling the cruise control main switch to CANCEL
e. Inspect the RES (RESUME) function.
1. Turn the main switch ON.
2. Drive at the required speed (43 km/h (27 mph) or higher).
3. Push the cruise control main switch to -/SET.
4. Cancel the cruise control system according to any of the above operations (other than turning the main switch OFF).
5. After pushing the cruise control main switch to +/ RES at a driving speed of more than 40 km/h (25 mph), check that the vehicle drives at the set speed.
HINT: The stored vehicle speed is retained even if vehicle speed goes below 40 km/h (25 mph) once. The previously stored vehicle speed can be resumed by pushing the cruise control main switch to +/RES when vehicle speed returned to approximately 40 km/h (25 mph) or more.
