COOLING FAN
45
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.
