Detection Condition
WARNING: This page is about a different car, the 2003 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
PCM monitors input voltages from fan control module. If voltage at PCM 104-pin harness connector terminal No. 44 remains low or high, PCM determines fan control circuit has a malfunction. This is a Continuous Monitor (other). MIL does not illuminate. PENDING CODE is available if PCM detects malfunction condition during first drive cycle. FREEZE FRAME DATA is available. DTC is stored in PCM memory.
