Toyota Sienna Service Manual: Speed sensor check (when using sst check wire)
(a) Check the speed sensor signal.
(1) Drive the vehicle straight forward. Drive the vehicle at a speed of 45 km/h (28 mph) or higher for several seconds and check that the ABS warning light goes off.
HINT: The signal check may not be completed if the vehicle has its wheels spun or the steering wheel turned during this check.
(b) Stop the vehicle.
NOTICE:
- Before performing the speed sensor signal check, complete the deceleration sensor and master cylinder pressure sensor checks.
- The speed sensor signal check may not be completed if the speed sensor signal check is started while turning the steering wheel or spinning the wheels.
- After the ABS warning light goes off, if
vehicle speed exceeds 80 km/h (50 mph), a
signal check code will be stored again.
Decelerate or stop the vehicle before the speed reaches 80 km/h (50 mph).
- If the signal check has not been completed, the ABS warning light blinks while driving and the ABS system does not operate.
HINT: When the signal check has been completed, the ABS warning light goes off while driving and blinks in the test mode pattern while stationary.
Master cylinder pressure sensor check (when using sst check wire)
(a) Leave the vehicle in a stationary condition and
release the brake pedal for 1 second or more, and
quickly depress the brake pedal with a force of 98 N
(10 kgf, 22 lbf) or more for 1 second or m ...
Yaw rate sensor check (when using sst check wire)
(a) Check the zero point voltage of the yaw rate sensor.
(1) Keep the vehicle in a stationary condition on a
level surface for 1 second or more.
(b) Check the output of the yaw rate sensor.

Pressure Control Solenoid "C" Performance (Shift
Solenoid Valve SL3)
SYSTEM DESCRIPTION
The ECM uses signals from the vehicle speed sensor to detect the actual gear
position (1st, 2nd, 3rd, 4th
or 5th gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory
to detect mechanical
troubles of the shift solenoid valves and valve bo ...

DTC P0607 Control Module Performance
DESCRIPTION
This DTC indicates a malfunction in the ECM.
HINT:
The ECM receives signals from each sensor to control all the functions of the
cruise control with the
microcomputer. When a malfunction is detected, fail-safe remains on until the
ignition sw ...
