Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P048012

Condition
The engine control module (ECM) continuously monitors the function of the engine cooling fan.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Voltage too high on the signal cable.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position II.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.





Substitute value
- None.

Possible source
- Signal cable between Engine control module (ECM) and electric cooling fan module is short-circuited to voltage.
- Damaged engine cooling fan (FC) control module.
- Damaged engine control module (ECM).

Fault symptom[s]
- Engine cooling/Engine overheats/runs hot
- Temperature control/A/C does not work
