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 TCM (ECT) malfunction detection conditions.
Some 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.
Some 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 → 6th → 6th (lock-up ON).
(2) Confirm engine braking using the S position. While driving with S6 range selected and 6th gear operating with lock-up on, move the shift lever toward "-" to downshift from 6 to 5, 5 to 4, 4 to 3, 3 to 2, 2 to 1.
(3) Repeat the above drive pattern three times or more.
NOTICE:
).
HINT:
*1: Drive the vehicle at a speed in top gear that will cause lock-up to engage. The vehicle can be driven at a speed lower than that in the above diagram under the lock-up condition.
NOTICE:
It is necessary to drive the vehicle for approximately 30 minutes to detect DTC P0711 (ATF temperature sensor malfunction).

DESCRIPTION
When the ignition switch is turned to ON, the battery voltage is applied to IGSW
of the ECM. The output signal from the MREL terminal of the ECM causes a current
to flow to the coil, closing the contact of the engine room junction block assemb ...
