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
(Malfunction is not detected when the atmospheric temperature is less than -10°C (14°F))
Driving note
Stop → 1st → 2nd → 3rd → 4th → 5th → 5th (lock-up ON).
NOTICE:
|
HINT: *1: Drive at such a speed in the uppermost gear, to engage lock-up. The vehicle can be driven at a speed lower than that in the above diagram under the lock-up condition.
NOTICE: If necessary to drive the vehicle for approximately 30 minutes to detect DTC P0711 (ATF temperature sensor malfunction). |
