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 ...

On–vehicle inspection
1. Inspect air–fuel ratio compensation system
Hint:
you can also check the system by choosing ”data monitor”,
then ”o2 sensor output voltage” on the monitor of the
hand–held tester.
Connect the hand–held tester to the terminal 23 (ox1a)
@ 7 (e1) and 21 (ox1b) @ 7 (e1) of the ecm.
