The multimeter must show a value of 10 ohms or less (closed circuit).
If the specification is not correct, there is an open circuit in the return (-) wire or input wire, provided the switch has previously been checked.
If the resistance is within specification, the return (-) wire and switch wire must still be checked for a short circuit to ground, a short circuit from pin-to-pin, and a short circuit to an external voltage source.
The multimeter must show a value of 100k ohms or more (open circuit).
If the circuit is not open, there is a short circuit to ground in the manual fan clutch circuit, provided the switch has been previously checked and is good.
Repair or replace the OEM harness. Refer to the OEM troubleshooting and repair manual.
