2.
Disconnect the 2P connector from the lock-up con'
trol solenoid valve A'lB assembly.
Measure the resistance between the No. 2 terminal
(solenoid valve A) of the connector and body
ground. and bet\iveen the No. 1 terminal (solenoid
valve B) and body ground.
STANDARD: 12 - 25 o
LOCK-UP CONTROLSOLENOID VALVECONNECTOR I2P)
Replace the lock-up control solenoid valve A/B
assembly if the resistance is out of specification
lf the resistance is within the standard, connect the
No. 1 terminal of the connector to the battery positive
terminal. A clicking sound should be heard Connect
the No. 2 terminal to the battery positive terminal. A
clicking sound should be heard. Replace the lock-up
control solenoid valve Ay'B assembly if no clicking
sound is heard when either terminal is connected to
the banerv Dositive terminal.
Check the lock-up control solenoid valve fluid pas-
sages for dust or debris, and replace as an assem
bly, if necessary.

Test
1. Disconnect the linear solenoid connector.

Measure the resistance between the No, 1 and the
No. 2 terminals.
STANDARD: About 5.0 o
lf the resistance is out of specification, replace the
linear solenoid assembly.
Connect the No. 1 terminal of the connector to the
battery positive terminal and the No. 2 terminal to
the battery negative terminal, A clicking sound
should be heard.
1.
lf a clicking sound is not heard, remove the linear
solenoid assembly.
Check the linear solenoid fluid passage for dust or
orn.
Connect the No. 1 terminal of the connector to the
battery positive terminal and the No. 2 te.minal to
the battery negative terminal. Make sure that the
valve moves.
Disconnect the negative battery terminal. and make
sure the valve releases. You can see valve move-
ment through the fluid passage in the mounting
surface of the linear solenoid assembly.

lf the valve binds, or moves sluggishly. or if the linear
solenoid does not operate, replace the linear solenoid
