Explanation and Corrective Action
Thermal Fault
Explanation:
The ambient temperature has exceeded the limit (Max T).
Corrective Action:
Check to see if the Cirscuit Cooling and Hammer Bank fans are
working. If both fans are working, you have a faulty Engine Controller
CBA.
If only one of the two fans is not working, check power at the Engine
Controller CBA for the fan that is not operating. If power is OK,
remove and replace the fan. If power is not OK remove and replace
the Engine Controller CBA.
If neither fan is working, either the Engine Controller CBA or the
Power Supply is malfunctioning. Check voltage output of the Power
Supply. If it is OK remove and replace the Engine Controller CBA. If
it is not OK, check the power source voltage. If the power source
voltage is OK, remove and replace the Power Supply. If the power
source voltage is incorrect, call an electrician.
