Toyota Sienna Service Manual: 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.

- Inspect the SET function.
- Turn the main switch on.
- Drive at the required speed (45 km/h (28 mph)
or higher).
- Push the cruise control main switch to -
(COAST)/SET.
- After releasing the switch, check that the vehicle
cruises at the set speed.

- Inspect the + (ACCEL) function.
- Turn the main switch on.
- Drive at the required speed (45 km/h (28 mph)
or higher).
- Push the cruise control main switch to -
(COAST)/SET.
- 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.
- 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).

- Inspect the - (COAST) function.
- Turn the main switch on.
- Drive at the required speed (45 km/h (28 mph)
or higher).
- Push the cruise control main switch to -
(COAST)/SET.
- 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.
- 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).

- Inspect the CANCEL function.
- Turn the main switch on.
- Drive at the required speed (45 km/h (28 mph)
or higher).
- Push the cruise control main switch to -
(COAST)/SET.
- 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

- Inspect the RES (RESUME) function.
- Turn the main switch on.
- Drive at the required speed (45 km/h (28 mph)
or higher).
- Push the cruise control main switch to -
(COAST)/SET.
- Cancel the cruise control system by performing
any of the above operations (other than turning
the main switch off).
- 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.
HINT:
Use the following procedures to troubleshoot the dynamic
laser cruise control system.
*: Use the intelligent tester

MIL Circuit
DESCRIPTION
The MIL (Malfunction Indicator Lamp) is used to indicate vehicle malfunctions
detected by the ECM.
When the ignition switch is turned to the ON position, power is supplied to the
MIL circuit, and the ECM
provides the circuit ground which illuminates the MIL.
