Inspection of Electric Control Components (A140L)

1. INSPECT OD 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 Ohms.

d. Connect the solenoid connector.




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


2. INSPECT OD MAIN SWITCH
a. Remove the console box.



b. Using an ohmmeter, measure the resistance between terminals 1 and 3.
- Switch ON - Resistance: Infinite Ohms
- Switch OFF - Resistance: 0 Ohms


3. INSPECT OD OFF INDICATOR



a. Turn on the ignition switch.
b. Turn off the OD main switch.
c. Check that the OD OFF indicator lights.

4. INSPECT WATER THERM SWITCH



a. Disconnect the thermo switch connector.
b. Using an ohmmeter, measure the resistance between terminal 1 and body ground.

Coolant temperature:
Below 43°C (109°F): 0 Ohms
Above 55°C (131°F): Infinite Ohms

c. Connect the thermo switch connector.
