INSPECTION PROCEDURE
1 Check shift solenoid valve SLN.
Check solenoid resistance and operation:
PREPARATION:
Disconnect the shift solenoid valve SLN connector.
CHECK:
(a)
Measure resistance between terminals 1 and 2 of sole-
noid connector.
(b) Connect positive lead with an 8 - 10 W bulb to terminal
1 of solenoid connector and negative lead to terminal
2, then check the movement of the valve.
OK:
(a) Resistance: 5.1 - 5.5
Ω
(b)
When battery positive voltage is sup-
plied.
Valve moves in direction shown in il-
lustration. (on the left)
When battery positive voltage is cut off.
Valve moves in direction shown in il-
lustration. (on the right)
Check solenoid operation:
PREPARATION:
Connect positive
lead of the variable power supply to termi-
nal 1 of solenoid connector and negative lead to terminal 2.
CHECK:
(a)
Check the movement of the valve when the voltage is
gradually increased.
(A current greater than 1A should not be supplied.)
(b) Check the movement of the valve when the voltage is cut
off.
OK:
(a) As the voltage is increased, the valve should move
slowly in the
direction.
(b) The valve should return in the direction.
NG Replace the shift solenoid valve SLN.
OK
