DTC P0482: Fan 3 Control Circuit
WARNING: This page is about a different variant/trim than selected.
P0482 - FAN 3 CONTROL CIRCUIT
| Description: | Monitors the medium fan control (MFC) primary circuit output from the powertrain control module (PCM). The test fails if the MFC output commanded on (grounded), excessive current draw is detected on the MFC circuit or, with the MFC circuit commanded off, voltage is not detected on the MFC circuit (the PCM expects to detect IGN START/RUN voltage through the medium speed FC relay coil to the MFC circuit). | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | When the MFCF PID reads YES, a concern is currently 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. During the KOEO and KOER self-test, the MFC circuit is cycled on and off. |
