Detection Condition

DTC is set when cooling fan relay coil control circuit input is low or high. PCM determines that cooling fan relay circuit has a malfunction. This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction condition in 2 consecutive drive cycles. Pending code is available if PCM detects malfunction condition during first drive cycle. Freeze Frame Data is available and DTC is stored in PCM memory.
