RANGE
DIAGNOSTIC NOTE
(50 mph) or more
HINT:
This test can be conducted when the vehicle speed is 80 km/h (50 mph) or more.
Perform this test while driving in 5th or 6th gear.
(h) Lightly depress the accelerator pedal and check that the engine speed does not change abruptly.
HINT:
When changing the accelerator pedal opening angle while driving, if the engine speed does not change
rapidly, lock-up is on.
Slowly release the accelerator pedal in order to decelerate, but do not fully release the pedal. (Fully
releasing the pedal will close the throttle valve and lock-up may be turned off automatically.)
