2GR-FE COOLING

– COOLING FAN ECU

CO–17

(e) Inspect the input signal and output current.

NOTICE:
Be sure to perform the inspection with the
radiator coolant temperature less than 95

C (203

F).

(1) Connect the 400 A probe of the ammeter to

terminal M+ of the cooling fan motor.

(2) Set the intelligent tester to the oscilloscope

function.

(3) Using the intelligent tester, check the waveform

between terminals RFC and E1 of the ECM.

Standard waveform

HINT:
•

If the input signal is abnormal, there is a
malfunction in the ECM or cooling fan ECU.

•

If the output current is abnormal even when
the input signal is normal, there is a
malfunction in the cooling fan ECU (RFC) or
motor.
