Toyota Sienna Service Manual: Freeze frame data
1. FREEZE FRAME DATA
(a) Whenever a DTC is detected or the ABS operates, the skid control ECU stores the current vehicle (sensor) state as freeze frame data.
The skid control ECU stores the number of times (maximum: 31) the ignition switch has been turned from OFF to the ON position since the last time the ABS was activated.
HINT:
- Freeze frame data at the time the ABS operates:

(b) Connect the intelligent tester to the DLC3.
(c) Turn the ignition switch to the ON position.
(d) On the tester display, select the FREEZE FRAME DATA.

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

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 ...
