INSPECTION OF ELECTRONIC CONTROL COMPONENTS

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: 11 - 15 ohm

d. Connect the solenoid connector.

2. INSPECT O/D MAIN SWITCH
3. INSPECT O/D OFF INDICATOR LIGHT
4. INSPECT WATER TEMPERATURE SWITCH




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

Resistance:
Water temperature Below 43 °C (109 °F) 0 ohm
Above 55 °C (131 °F) Infinity ohm




c. Connect the water temperature switch connector.







5. INSPECT NEUTRAL START SWITCH
Using an ohmmeter, check the continuity of the terminals for each switch position shown in the table.
