DTC P0480: FAN 1 CONTROL CIRCUIT
| For Relay Controlled Electric Cooling Fan | |||
| Description: | This DTC sets when the PCM grounds the LFC circuit and excessive current draw is detected on the LFC circuit; or with the LFC circuit not grounded by the PCM the voltage is not detected on the LFC circuit (the PCM expects to detect VPWR voltage coming through the low speed fan control relay coil to the LFC circuit). | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | When the LFC PID reads YES, a concern is present. During the key ON engine OFF (KOEO) self-test, the cooling fan is cycled ON and OFF. A short to voltage can only be detected when the PCM is grounding the LFC circuit. During the KOEO and key ON engine running (KOER) self-test, the LFC circuit is cycled ON and OFF. | ||
| For Variable Speed Electric Cooling Fan | |||
| Description: | This DTC sets if the PCM detects the voltage on the FCV circuit is not within the expected range. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | During the key ON engine OFF (KOEO) self-test, the cooling fan is cycled ON and OFF. | ||
| For Cooling Fan Clutch | |||
| Description: | This DTC sets if the PCM detects the voltage on the FCV circuit is not within the expected range. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | During the key ON engine OFF (KOEO) self-test, the cooling fan is cycled ON and OFF. | ||
