Toyota Tundra Service Manual: Monitor Drive Pattern

MONITOR DRIVE PATTERN

1. TEST MONITOR DRIVE PATTERN FOR ECT

CAUTION:

Perform this drive pattern on a level surface and strictly observe the posted speed limits and traffic laws while driving.

HINT:

Performing this drive pattern is one method to simulate the malfunction detection conditions of the ECT.

The DTCs may not be detected through ordinary, everyday driving. Also, DTCs may not be detected through this drive pattern.

(a) Preparation for driving

(1) Warm up the engine sufficiently (engine coolant temperature is 60°C (140°F) or higher).

(2) Drive the vehicle when the atmospheric temperature is -10°C (14°F) or higher.

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

(b) Drive pattern

(1) Drive the vehicle through all the gears.

Stop → 1st → 2nd → 3rd → 4th → 5th → 5th (lock-up ON) → 6th → 6th (lock-up ON).

(2) Repeat the above drive pattern 3 times or more.

NOTICE:

• When using the Techstream, the monitor status can be checked in the Data List (See page ).
• In the event that the drive pattern must be interrupted (due to traffic conditions or other factors), the drive pattern can be resumed and, in most cases, the monitor can be completed.

HINT:

*: Drive at such a speed in the uppermost gear so as to engage lock-up. The vehicle can be driven at a speed lower than the speed shown in the above diagram in lock-up.

NOTICE:

It is necessary to drive the vehicle for approximately 30 minutes to detect DTC P0711 (No. 1 ATF temperature sensor malfunction).
