or open
Circuit Description
Ignition voltage is supplied directly to the cooling fan relay coil. The ECM controls the relay by grounding the control
circuit. When the ECM is commanding a command ON, the voltage of the control circuit should be low (near 0 volt).
When the ECM is commanding the control circuit should be high (near battery voltage). If the fault detection circuit
senses a voltage other than what is expected, the fault line status will change causing the fault code to set.
