STEP 8. Check the fan control relay.

Refer to

P.14-19

.

Q: Is the fan control relay in good condition?

YES :

Go to Step 9.

NO :

Replace the fan control relay. Then go to
Step 24.

STEP 9. Check the fan control relay connector
A-10X.

Q: Is the connector in good condition?

YES :

Go to Step 10.

NO :

Repair the connector or replace the relay
box. Then go to Step 24.

STEP 10. Check the harness wire between fan
control relay connector A-10X terminal 2 and fan
controller connector A-20 terminal 3.

Q: Is the harness wire in good condition?

YES :

Go to Step 11.

NO :

Repair the damaged harness wire. Then go
to Step 24.

STEP 11. Measure the terminal voltage at fan
control relay connector A-10X.

(1) Disconnect fan control relay connector A-10X

(remove the fan control relay) and measure relay
box side connector.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between fan control relay

connector A-10X terminal 1 and body earth.

•

The voltage should measure system voltage.

(4) Turn the ignition switch to the "LOCK" (OFF)

position.

(5) Connect fan control relay connector A-10X

(install the fan control relay).

Q: Is the measured voltage system voltage?

YES :

Go to Step 14.

NO :

Go to Step 12.
