Toyota Corolla Repair Manual: Inspection
1. Cooling fan relay
- Inspect the cooling fan relay continuity.
- Using an ohmmeter, check that there is continuity
between terminals 1 and 2.
If there is no continuity, replace the relay.
- Check that there is no continuity between terminals
3 and 5.
If there is continuity, replace the relay.
- Apply battery voltage across terminals 1 and 2.
- Using an ohmmeter, check that there is continuity
between terminals 3 and 5.
If there is no continuity, replace the relay.
2. Cooling fan relay no.2
- Inspect the cooling fan relay continuity.
- Using an ohmmeter, check that there is continuity
between terminals 1 and 2.
If there is no continuity, replace the relay.
- Using an ohmmeter, check that there is continuity
between terminals 3 and 4.
If there is no continuity, replace the relay.
- Check that there is no continuity between terminals
3 and 5.
If there is continuity, replace the relay.
- Apply battery voltage across terminals 1 and 2.
- Using an ohmmeter, check that there is continuity
between terminals 3 and 5.
If there is no continuity, replace the relay.
3. Cooling fan resistor
- using an ohmmeter, measure the resistance between the terminals.
Resistance: 1.17 – 1.43 W at 20 c (68 f)
On–vehicle inspection
1. Check cooling fan operation with low temperature (below 83 c (181 f))
Turn the ignition switch on.
check that the cooling fan stops.
Hint:
if not, check the cooling fan relay and wa ...
