DTC P0482 DETECTION CONDITION AND POSSIBLE CAUSES

DTC P0482 Cooling fan relay No. 4 control circuit malfunction
DETECTION CONDITION  California emission regulation applicable ATX model 
  • The PCM monitors the cooling fan relay No. 4 control signal voltage and current. If the following conditions are met, the PCM determines that there is the cooling fan relay No. 4 control circuit problem.
    • The PCM turns the cooling fan relay No. 4 off, but the voltage of the cooling fan relay No. 4 control signal remains low.
    • The PCM turns the cooling fan relay No. 4 on, but the current of the cooling fan relay No. 4 control signal remains high.

Diagnostic support note 
  • This is a continuous monitor (Other).
  • The MIL does not illuminate.
  • PENDING CODE is available if the PCM detects the above malfunction condition.
  • FREEZE FRAME DATA is available.
  • The DTC is stored in the PCM memory.
Except for California emission regulation applicable ATX model 
  • PCM monitors cooling fan relay No. 4 control signal. If voltage remains low or high, PCM determines that fan relay circuit has a malfunction.

Diagnostic support note
