Lock-Up Mechanism Inspection

INSPECT LOCK-UP MECHANISM
a. Warm up the coolant and ATF.

b. Connect a voltmeter to terminals between ECT and E(1).
c. Connect a tachometer to terminal IG (-)
d. Select the normal pattern.
e. Drive at around 50 km/h (31 mph) until 7, 5 or 3 V appears on the voltmeter (this is lock-up range).
f. Depress the accelerator pedal and read the tachometer. If there is a big jump in engine rpm there is no lock-up.
