TEST

ACTION

APPLICABILITY

1

Turn the ignition on.
With the DRBIII

t

, actuate the High Speed Radiator Fan Relay.

Are both Radiator Fan operating at high speed?

All

Yes

→

Refer to the INTERMITTENT CONDITION symptom in the
Driveability category.
Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC.

No

→

Go To

2

2

Turn the ignition off.
Remove both of the Radiator Fan Relays (#2 and #3) from the PDC.
Turn the ignition on.
NOTE: A voltage measurement must be taken at both Radiator Fan Relay
Fused Ignition Switch Output circuits in the PDC.
Measure the voltage of the Fused Ignition Switch Output circuit at the radiator Fan
Relay connector in the PDC.
Is the voltage above 11.0 volts at both relay connectors?

All

Yes

→

Go To

3

No

→

Repair the Fused Ignition Switch Output circuit. Check and
replace any open fuses.
