a. Using a suitable ohmmeter, check that continuity exists between terminals 1 and 2, Fig. 6.
b. Using a suitable ohmmeter, check that no continuity exists between terminals 3 and 4.
c. If continuity is not as specified, replace relay.
d. Apply battery voltage across terminals 1 and 2, then check for no continuity between terminals 3 and 4.
e. If continuity exists, replace relay.

Connect a suitable ammeter and battery to fan motor connector, Fig. 2. Ensure motor rotates smoothly and current is 4.2-5.4 amps on sedan
models with manual transaxle, 5.8-7.4 amps on sedan models with automatic transaxle and 4WD models with manual transaxle or 8.8-10.8 amps
on 2WD wagon models with automatic transaxle.

TROUBLESHOOTING
1.
If coolant temperature is low (below 172°F), proceed as follows:
a. Turn ignition switch on and ensure cooling fan is not operating.
b. If fan is operating, a faulty fan relay and/or temperature switch is indicated. Check for separated electrical connectors or severed wire
between relay and temperature switch.
c. Disconnect temperature switch wire, then check that fan rotates.
d. If fan does not rotate, check fan relay, fan motor, engine main relay and fuse. Check for short circuit between fan relay and temperature
switch.
e. Connect temperature switch wire.
2.
If coolant temperature is high (above 190°F), proceed as follows:
a. Raise engine temperature to above 190°F, then check that fan rotates.
b. If fan does not rotate, replace temperature switch.
c. Allow coolant temperature to drop below 172°F. Fan should stop rotating.
d. If fan does not stop rotating, replace temperature switch.
