PROBLEM SYMPTOM CONFIRMATION
HINT:
(a) Inspect the SET function.
*a |
ON-OFF |
*b |
-SET |
(1) Turn the dynamic radar cruise control system on using the cruise control main switch (ON-OFF button).
(2) Check that the cruise control indicator light illuminates in the combination meter assembly.
(3) Drive at a speed between approximately 50 km/h (31 mph) and 180 km/h (110 mph).
(4) Push the cruise control main switch to -SET.

(5) Check that the cruise control indicator remains illuminated, the cruise control SET indicator illuminates in the combination meter assembly and the set speed is displayed on the multi-information display.
(6) After releasing the switch, check that the vehicle maintains the set speed.
(b) Inspect the + (ACCEL) function.
(1) Turn the dynamic radar cruise control system on using the cruise control main switch (ON-OFF button).
*a |
ON-OFF |
*b |
-SET |
(2) Drive at a speed between approximately 50 km/h (31 mph) and 180 km/h (110 mph).
(3) Push the cruise control main switch to -SET.
(4) Constant speed control mode:
Check that vehicle speed increases while the cruise control main switch is pushed to +/RES, and that the vehicle maintains the newly set speed when the switch is released.
Vehicle-to-vehicle distance control mode:
Check that the vehicle speed increases in increments of approximately 1 km/h (or 1 mph)* or 5 km/h (or 5 mph) while the cruise control main switch is pushed to +/RES and that the vehicle maintains the newly set speed when the switch is released.
*a |
+RES |
(5) Push the cruise control main switch to +RES and then release it immediately. Check that the vehicle speed increases* (tap-up control).
HINT:
*: Constant speed control mode: increases by approximately 1 km/h or 1 mph; vehicle-to-vehicle distance control mode: increases by approximately 1 km/h or 1 mph.
(c) Inspect the - (COAST) function.
(1) Turn the dynamic radar cruise control system on using the cruise control main switch (ON-OFF button).
*a |
ON-OFF |
*b |
-SET |
(2) Drive at a speed between approximately 50 km/h (31 mph) and 180 km/h (110 mph).
(3) Push the cruise control main switch to -SET.
(4) Constant speed control mode:
*a |
-SET |
Check that vehicle speed decreases while the cruise control main switch is pushed to -/SET, and that the vehicle maintains the newly set speed when the switch is released.
Vehicle-to-vehicle distance control mode:
Check that the vehicle speed decreases in increments of approximately 1 km/h (or 1 mph)* or 5 km/h (or 5 mph) while the cruise control main switch is pushed to -/SET and that the vehicle maintains the newly set speed when the switch is released.
(5) Push the cruise control main switch to -SET, and then release it immediately. Check that the vehicle speed decreases* (tap-down control).
HINT:
*: Constant speed control mode: decreases by approximately 1 km/h or 1 mph; vehicle-to-vehicle distance control mode: decreases by approximately 1 km/h or 1 mph.
*a |
ON-OFF |
*b |
-SET |
(d) Inspect the CANCEL function.
(1) Turn the dynamic radar cruise control system on using the cruise control main switch (ON-OFF button).
(2) Drive at a speed between approximately 50 km/h (31 mph) and 180 km/h (110 mph).
(3) Push the cruise control main switch to -SET.
(4) When any of the following are performed, check that control of vehicle speed by the dynamic radar cruise control system is canceled and that the normal driving mode (no control of vehicle speed by the dynamic radar cruise control system) resumes.
*a |
CANCEL |
(e) Inspect the RES (RESUME) function.
(1) Turn the dynamic radar cruise control system on using the cruise control main switch (ON-OFF button).
*a |
ON-OFF |
*b |
-SET |
(2) Drive at a speed between approximately 50 km/h (31 mph) and 180 km/h (110 mph).
(3) Push the cruise control main switch to -SET.
(4) Cancel control of vehicle speed by the dynamic radar cruise control system by performing any of the CANCEL functions (other than turning the dynamic radar cruise control system off using the cruise control main switch (ON-OFF button)).
(5) Push the cruise control main switch to +RES while driving the vehicle at a speed of more than approximately 40 km/h (25 mph), and check that the vehicle resumes the speed set prior to cancellation and that the cruise control SET indicator illuminates.
HINT:
The stored vehicle speed is retained even if vehicle speed drops below approximately 40 km/h (25 mph). The previously stored vehicle speed can be resumed by pushing the cruise control main switch to +RES when the vehicle speed has returned to approximately 40 km/h (25 mph) or more.

Cruise Control Switch Circuit
DESCRIPTION
This circuit sends signals to the ECM depending on the cruise control main switch
condition.
The battery supplies the positive (+) battery voltage to the cruise control main
switch. Then terminal CCS of the ECM receives the voltage as the signal according
to the switch condition. ...
Diameter of the Tire is not Uniform (C1337)
DESCRIPTION
The skid control ECU (brake actuator assembly) measures the speed of each wheel
by receiving signals from the speed sensors. These signals are used for recognizing
whether all 4 wheels are operating properly. Therefore, all wheel signals must indicate
the same speed.
