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 cooling fan relay No. 1 control signal at PCM 30-pin harness connector terminal "4L". If voltage at PCM 30-pin harness connector terminal "4L" remains low or high, PCM determines fan relay No. 1 circuit has malfunction. This is a Continuous Monitor (other). MIL does not come on. PENDING CODE is available if PCM detects malfunction condition during first drive cycle. FREEZE FRAME DATA is available. DTC is stored in PCM memory if PCM detects malfunction condition in two consecutive drive cycles.
