Toyota Sienna Service Manual: Monitor drive pattern

Toyota Sienna Service Manual / U151e automatic transaxle / Automatic transaxle system / Monitor drive pattern

1. MONITOR DRIVE PATTERN FOR ECT TEST

(a) Perform this drive pattern as one method to simulate the detection conditions of the ECT malfunctions. (The DTCs may not be detected due the actual driving conditions. And some codes may not be detected through this drive pattern.)

HINT: Preparation for driving

Warm up the engine sufficiently. (Engine coolant temperature is 60°C (140°F) or higher)
Drive the vehicle when the atmospheric temperature is -10°C (14°F) or higher.

(Malfunction is not detected when the atmospheric temperature is less than -10°C (14°F))

Driving note

Drive the vehicle through all gears.

Stop → 1st → 2nd → 3rd → 4th → 5th → 5th (lock-up ON).
Repeat the above driving pattern three times or more.

NOTICE:

The monitor status can be checked using the OBD II scan tool or intelligent tester. When using the intelligent tester, monitor status can be found in the "ENHANCED OBD II / DATA LIST" or under "CARB OBD II".
In the event that the drive pattern must be interrupted (possibly due to traffic conditions or other factors), the drive pattern can be resumed and, in most cases, the monitor can be completed.
Perform this drive pattern on a level road as much as possible and strictly observe the posted speed limits and traffic laws while driving.
