Checking The Component

HINT: The diagnostic trouble code (DTC) may due to a damaged cooling fan for the control module boxes. If diagnostic trouble code (DTC) ECM-680X is stored it must be remedied first. 

Activate the cooling fan for the control module box. Check the function. There must be a buzzing noise from the cooling fan when the fan for the control module box is activated.

Check that the air ducts for the control module box are not blocked.

Remedy as necessary.
