Lock-up Control Solenoid Valve A/B
NOTE: Lock-uD control solenoid valves A and B must be
removed/replaced as an assemblv.
l. Disconnect 2P connector trom the lock-uo control
solenoid valve A/8.
2. Measure the resistance between the No. 1 terminal(solenoid valve A) ot the lock-up cont.ol solenoid
valve connector and body ground, and between the
No. 2 terminal (solenoid valve B) and body ground.

lf the .esistance is within the standard, connect the
No. 1 terminal ot the lock-uo control solenoid valve
connector to the battery positive terminal. A click-
ing sound should be heard. Connect the No. 2 ter-
minal to the battery positive terminsl. A clicking
sound should be heard. Replace the lock-up control
solenoid valve assembly if no clicking sound is heard.
