With Manual Transaxle
SYSTEM INSPECTION1. Verify that the engine is cold.
2. Turn the ignition switch to ON.
3. Verify that the cooling fan is not operating.
4. If the cooling fan is operating, do as follows.
SST NGS:
a. Connect the Special Service Tools (SST)s New Generation Star (NGS) tester to the data link connector-2.
b. By using the "PID/DATA MONITOR AND RECORD" function, verify that the cooling fan control signal is OFF.
I. If the cooling fan control signal is ON, check the following.
^ ECM terminal voltage.
^ Engine coolant temperature signal.
II. If the cooling fan control signal is OFF check the following.
^ Cooling fan relay.
^ Short circuit in wiring harnesses and connectors (Main relay - Fan relay - ECM).
DLC-1 & SST:
5. Connect the SST and set system select switch to 1 and self test switch to SELF TEST.
6. Rotate the throttle link by hand and verify that the cooling fan operates.
7. If the cooling fan does not operate, do as follows.
a. Connect the SST to the data link connector-2.
b. Turn the cooling fan relay from OFF to ON by using the "SIMULATION TEST" function and check for the cooling fan operation.
I. If the cooling fan operates, check the following.
^ ECM terminal voltage
^ Test mode signal
^ Closed throttle position switch signal
II. If the cooling fan does not operate, do as follows.
a. Turn the cooling fan relay from OFF to ON by using the "SIMULATION TEST" function. Operate the cooling fan relay and check if the operation sound of the relay is heard.
b. If the operation sound is heard, check the following.
^ Wiring harnesses and connectors (Cooling fan relay - Cooling fan motor)
^ Cooling fan motor
c. If the operation sound is not heard, check the following.
^ Cooling fan relay
^ Open circuit in wiring harnesses and connectors (Main relay - Cooling fan relay - ECM)
