Note! When reading off the Diagnostic trouble code (DTC) status, other stored diagnostic trouble codes (DTCs) and their status will be listed.

- Read off diagnostic trouble code (DTC) status. Check the status of the relevant Diagnostic Trouble Code (DTC).

Was the status of the relevant Diagnostic Trouble Code (DTC) displayed as permanent?
Yes - Skip to "Checking Component"
No - Continue below.


Checking component and wiring
The engine fan control module has previously registered that the fan blade was blocked or that the temperature in the engine fan control module was too high, but the fault is no longer present.

Check that nothing is loose in the vicinity of the engine cooling fan (FC) which can temporarily stop the fan blade.


Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
--Testing Complete.--


Checking Component
Check that the fan blade rotates easily and that nothing is obstructing it.

Replace the engine cooling fan control module if there is nothing obstructing the fan blade and it still does not rotate freely.

Remedy as necessary.
