Toyota Camry (XV70): Road Test

ROAD TEST

HINT:

• The dynamic radar cruise control system has 2 cruise control modes: constant speed control mode and vehicle-to-vehicle distance control mode.
• Vehicle-to-vehicle distance control mode is selected by default when the dynamic radar cruise control system is turned on using the cruise control main switch.

PROBLEM SYMPTOM CONFIRMATION (CONSTANT SPEED CONTROL MODE)

(a) Inspect the SET function.

(1) Push and hold the cruise control main switch for 1.5 seconds or more with the dynamic radar cruise control system off to change to constant speed control mode.

(2) Check that the cruise control indicator (vehicle-to-vehicle distance control mode) turns off and the cruise control indicator (constant speed control mode) illuminates.

(3) Drive at a speed between approximately 30 km/h (20 mph) and 200 km/h (125 mph).

(4) Push the -SET switch.

(5) Check that the cruise SET indicator illuminates at this time.

(6) After releasing the switch, check that the vehicle maintains the set vehicle speed.

HINT:

If the vehicle speed decreases to 16 km/h (10 mph) less than the set vehicle speed such as when driving on a steep slope, control of vehicle speed by the constant speed control mode is canceled.

(b) Inspect the + (ACCEL) function.

(1) Push and hold the cruise control main switch for 1.5 seconds or more with the dynamic radar cruise control system off to change to constant speed control mode.

(2) Drive at a speed between approximately 30 km/h (20 mph) and 200 km/h (125 mph).

(3) Push the -SET switch.

(4) Check that vehicle speed increases while the +RES switch is pushed, and that the vehicle maintains the newly set vehicle speed when the switch is released.

(5) Push the +RES switch and then release it immediately. Check that vehicle speed increases by approximately 1 km/h (1 mph) (tap-up control).

HINT:

If the difference between the set vehicle speed and actual vehicle speed is 5 km/h (3 mph) or more, tap-up control will not operate.

(6) Confirm that the set vehicle speed displayed on the multi-information display changes when the +RES switch is pushed.

(c) Inspect the - (COAST) function.

(1) Push and hold the cruise control main switch for 1.5 seconds or more with the dynamic radar cruise control system off to change to constant speed control mode.

(2) Drive at a speed between approximately 30 km/h (20 mph) and 200 km/h (125 mph).

(3) Push the -SET switch.

(4) Check that vehicle speed decreases while the -SET switch is pushed, and the vehicle maintains the newly set vehicle speed when the switch is released.

HINT:

If the vehicle speed decreases to approximately 30 km/h (20 mph), control of vehicle speed by the constant speed control mode is canceled.

(5) Push the -SET switch, and then release it immediately. Check that vehicle speed decreases by approximately 1 km/h or 1 mph (tap-down control).

HINT:

If the difference between the set vehicle speed and actual vehicle speed is 5 km/h (3 mph) or more and the -SET switch is pushed, the vehicle speed is stored as the set vehicle speed and the vehicle will be driven in constant speed control mode.

(6) Confirm that the set vehicle speed displayed on the multi-information display changes when the -SET switch is pushed.

(d) Inspect the CANCEL function.

(1) Push and hold the cruise control main switch for 1.5 seconds or more with the dynamic radar cruise control system off to change to constant speed control mode.

(2) Drive at a speed between approximately 30 km/h (20 mph) and 200 km/h (125 mph).

(3) Push the -SET switch.

(4) When any of the following are performed, check that control of vehicle speed by the constant speed control mode is canceled and that normal driving resumes (no control of vehicle speed by the constant speed control mode).

• Depressing the brake pedal.
• Moving the shift lever from D to any other position.
• Pushing the CANCEL switch.
• Turning the constant speed control mode off using the cruise control main switch (the stored vehicle speed in the ECM is not maintained).

(e) Inspect the RES (RESUME) function.

(1) Push and hold the cruise control main switch for 1.5 seconds or more with the dynamic radar cruise control system off to change to constant speed control mode.

(2) Drive at a speed between approximately 30 km/h (20 mph) and 200 km/h (125 mph).

(3) Push the -SET switch.

(4) Depress the brake pedal to cancel control of vehicle speed by the constant speed control mode.

(5) Push the +RES switch while driving the vehicle at a speed of more than approximately 30 km/h (20 mph), and check that the vehicle resumes the speed set prior to cancellation and that the cruise SET indicator illuminates.
