Detection Condition

DTC is set when cooling fan relay coil control circuit input is to low or to high. Powertrain Control Module (PCM) determines that cooling fan relay circuit has a malfunction. This is a continuous monitor (CCM). MIL illuminates if PCM detects malfunction condition in 2 consecutive drive cycles. Pending code is available if PCM detects malfunction conditions during first drive cycle. Freeze Frame Data is available and DTC is stored in the PCM memory.
