P0482 - FAN 3 CONTROL CIRCUIT - DTC CHART
| Description: This DTC sets when the MFC output is commanded on (grounded) and excessive current draw is detected on the MFC circuit; or when the MFC circuit is commanded off and voltage is not detected on the MFC circuit. The PCM expects to detect VPWR voltage through the medium speed fan control (FC) relay coil to the MFC circuit. | |||
Possible Causes:
|
|||
| Diagnostic Aids: When the MFC_F PID reads YES, a concern is present. An open circuit or short to ground can only be detected when the PCM is not grounding the MFC circuit. A short to voltage can only be detected when the PCM is grounding the MFC circuit. | |||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
| All | GO to Pinpoint Test KF . | ||
