FAN RELAY CONTROL CIRCUIT TEST
If continuity was not measured, repair or replace
wiring/connector as required.
If cooling fan relay, relay input voltage and relay
control circuit continuity tested good, the problem
is related to the ECM. Refer to the
ELECTRONIC
FUEL INJECTION
section for ECM testing.
Fan Input Voltage Test
Ensure cooling fan relay and fuse are installed.
Disconnect the radiator cooling fan connector.
Set multimeter to Vdc.
Test for battery voltage at the radiator cooling fan
connector BROWN/WHITE wire.

cuit continuity.
If battery voltage was not measured, test fan pow-
er circuit continuity.
