FAN MOTOR OPERATION
WHEN THE IGNITION SW IS TURNED ON, CURRENT FROM THE ECU-IG FUSE FLOWS TO THE FAN NO. 1 RELAY (COIL SIDE) AND
THE FAN NO. 2 RELAY (COIL SIDE) "TERMINAL 2 OF THE A/C SINGLE PRESSURE SW "TERMINAL 3 "TERMINAL 2 OF THE A/C
WATER TEMP. SW "TERMINAL 1 "GROUND, AND THE FAN NO. 1 RELAY AND THE FAN NO. 2 RELAY ARE TURNED ON.
AT THE SAME TIME THAT THIS CURRENT FLOWS, CURRENT FROM THE ECU-IG FUSE FLOWS TO THE E/G MAIN RELAY (COIL
SIDE) "GROUND, AND THE E/G MAIN RELAY IS TURNED ON. AS A RESULT, CURRENT FROM THE ALT FUSE FLOWS TO THE CDS
FA N FUSE AND RDI FAN FUSE.
*LOW SPEED OPERATION
WHEN THE IGNITION SW IS TURNED ON AND THE A/C IS ACTIVATED, CURRENT FLOWS FROM THE MG/C RELAY (POINT SIDE) "
THE FAN NO. 3 RELAY (COIL SIDE) "GROUND, AND THE FAN NO. 3 RELAY IS TURNED ON. AS A RESULT, CURRENT FROM THE
CDS FAN FUSE FLOWS TO TERMINAL 2 OF THE A/C CONDENSER FAN MOTOR "TERMINAL 1 "THE FAN NO. 2 RELAY (POINT
SIDE) "THE FAN NO. 3 RELAY (POINT SIDE) "TERMINAL 2 OF THE RADIATOR FAN MOTOR "TERMINAL 1 "GROUND, AND
BOTH OF THE FAN MOTORS, WITH THE RESULT THAT THE FANS ARE ACTIVATED AT LOW SPEED.
IF THE ENGINE COOLANT TEMPERATURE IS APPROX. 90
C (194
F) OR LESS, AND THE REFRIGERANT PRESSURE IS APPROX.
15.5 KG/CM
2 (1323 KPA, 191.7 PSI) OR LESS, BOTH THE A/C WATER TEMP. SW AND THE A/C SINGLE PRESSURE SW ARE CLOSED,
SO THAT THE FAN NO. 1 RELAY AND THE FAN NO. 2 RELAY ARE TURNED ON. AS A RESULT, BOTH OF THE FAN MOTOR OPERATE
AT LOW SPEED.
*HIGH SPEED OPERATION
WHEN, DURING A/C OPERATION, THE REFRIGERANT PRESSURE BECOMES HIGHER THAN ORDINARY LEVEL (APPROX. 15.5
KG/CM
2 (1323 PSI. 191.7 KPA)), THE A/C SINGLE PRESSURE SW IS TURNED OFF. AS A RESULT, THE FAN NO. 1 RELAY AND THE
FAN NO. 2 RELAY ARE TURNED OFF, AND THE CURRENT FLOWS FROM THE RDI FAN FUSE TO FAN NO. 1 RELAY (POINT SIDE) "
TERMINAL 2 OF THE RADIATOR FAN MOTOR "TERMINAL 1 "GROUND, AND CURRENT FROM THE CDS FAN FUSE FLOWS TO
TERMINAL 2 OF THE A/C CONDENSER FAN MOTOR "TERMINAL 1 "THE FAN NO. 2 RELAY (POINT SIDE) "GROUND, AND TO
BOTH OF THE FAN MOTORS IN PARALLEL, THUS CAUSING THE FAN MOTORS TO OPERATE AT HIGH SPEED.
NOTE THAT, BECAUSE THE CURRENT FLOWS IN THE SAME MANNER EVEN IF THE COOLANT TEMPERATURE IS APPROX. 90
C
(194
F) OR HIGHER, THE FAN MOTORS STILL OPERATE AT HIGH SPEED.
