CRUISE CONTROL: DYNAMIC LASER CRUISE CONTROL SYSTEM: ROAD TEST

ROAD TEST

1. 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 (28 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 above 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 (25 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.
