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 (45 km/h (28 mph) or higher).
3. Push the cruise control main switch to - (COAST)/SET.
4. After releasing the switch, check that the vehicle cruises at the set speed.
b. Inspect the + (ACCEL) function.
1. Turn the main switch on.
2. Drive at the required speed (45 km/h (28 mph) or higher).
3. Push the cruise control main switch to - (COAST)/SET.
4. Check that vehicle speed increases while the cruise control main switch is pushed to + (ACCEL)/RES (RESUME), and that the vehicle cruises at the newly set speed when the switch is released.
5. Push the cruise control main switch to + (ACCEL)/RES (RESUME) and then release it immediately 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 mph (for USA) or 5 km/h (for Canada).
c. Inspect the - (COAST) function.
1. Turn the main switch on.
2. Drive at the required speed (45 km/h (2.8 mph) or higher).
3. Push the cruise control main switch to - (COAST)/SET.
4. Check that vehicle speed decreases while the cruise control main switch is pushed to - (COAST)/SET, and that the vehicle cruises at the newly set speed when the switch is released.
5. Push the cruise control main switch to - (COAST)/SET, and then release it immediately 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 mph (for USA) or 5 km/h (for Canada).
d. Inspect the CANCEL function.
1. Turn the main switch on.
2. Drive at the required speed (45 km/h (28 mph) or higher).
3. Push the cruise control main switch to - (COAST)/SET.
4. When performing any one of the following, check that the cruise control system is canceled and that the normal driving mode is reset.
- Depressing the brake pedal
- Moving the shift lever from the D or 4 to the N, 3, 2. or L position
- Turning the main switch off (the stored vehicle speed in the ECM is not maintained.)
- 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 (45 km/h (28 mph) or higher).
3. Push the cruise control main switch to - (COAST)/SET.
4. Cancel the cruise control system by performing any of the operations (other than turning the main switch off).
5. After pushing the cruise control main switch to + (ACCEL)/RES (RESUME) at a driving speed of more than 40 km/h (2.5 mph), check that the vehicle resumes the speed set prior to the cancellation.
HINT: The stored vehicle speed is retained even if vehicle speed drops below 40 km/h (25 mph) once. The previously stored vehicle speed can be resumed by pushing the cruise control main switch to + (ACCEL)/RES (RESUME) when vehicle speed returned to approximately 40 km/h (25 mph) or more.
