DIAGNOSIS
Cooling Fan - With Fan Controller
Each cooling fan controller has the part number stamped on the housing or on the mounting bracket to identify the controller. It is important that the
correct controller be installed for proper operation. Locate the correct cooling fan controller diagnosis procedure and wiring diagram. Then, determine
the position (open or closed) of each switch in the system (listed at top of diagnosis chart). Then, locate the appropriate row of the diagnosis chart to
correspond with the switch positions. Follow the row to the right to determine if the letter F appears in that row. An E in the column at the right
indicates that the component listed at the top of that column should be energized for the switch positions.
If the position of a switch cannot be determined, disconnect the connector from the switch. This will be the same as an open switch in the circuit. To
check a switch for proper operation, disconnect the connector and connect a self-powered test lamp across the switch. Then, cycle the switch. The test
lamp should glow when the switch closes and should go out when the switch opens.
