Toyota Corolla (E120): 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)

Terminals of ecu
1. Inspect integration relay
Disconnect the connector from the integration relay.
check the continuity between each terminal of the disconnected connector
and the body ground, as
shown in the illustration and table.

Disabling the TRAC system
If the vehicle gets stuck in mud, dirt or snow, the TRAC system may reduce power
from the engine to the wheels. Pressing
to turn the system off may make it
easier for you to rock the vehicle in order to free it.
To turn the TRAC system off, quickly press and release
.
