Overdrive Solenoid: Testing and Inspection

1. INSPECT O/D SOLENOID




a. Disconnect the solenoid connector.
b. Apply voltage between terminals 1 and 2. At this time, confirm that a solenoid operation sound in heard.




c. Using an ohmmeter, measure the solenoid coil resistance between terminals 1 and 2.

Resistance: 13 ± 2 ohm

d. Connect the solenoid connector.




e. Turn on the ignition switch and disconnect the thermo sensor wire.
f. Confirm that operation sounds of the solenoid can be heard if the O/D main switch is repeatedly turn on and off.
g. Turn off the ignition switch and connect the thermo switch.
