1. Checks for battery + at relay harness connector.
2. Jumpering terminals "1" to "4" bypasses the relay which should cause the fan to run if fan motor and wiring to the motor are good.
3. Grounding the test terminal should cause the ECM to ground CKT 535. At this point, the test light should light if the ECM is good and CKT 535 isn't open.
4. This checks for battery + and ground to the fan motor. A test light "on" at this point indicates a faulty fan motor connection or motor.
