Read fault codes 2005 ford f 250 6.0 diesel without buying a expensive scan tool .

Just install cooling fan and wire to an aftermarket toggle switch. U can manually turn on/off cooling fan

check all fluid levels including the radiator at the cap. Run the fault codes and find out what put the light on. It is there to advise you that continued running may result in serious engine/ transmission damage so check it out asap.

check engine immobiliser and crank position sensor . Run fault codes and replace faulty units.

Hello
The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

Do not buy it. These cars a sent from HELL!!!!!!!!!!!!

the only way would be with a scan tool. the tool would read the readings of the pedal sensor and also have you scanned the computer for any stoored codes, even if the check engine light is not on. another problem may be the throtlebody itself, the pedal sensor and the two throtlebody sensors all work together to accel, i would have it tested before buying it, its costly and i would hate to see you spend the money for a part you dont need,good day

The blinking LED indicates that there is a fault in you A/C-heater control system.

The A/C-heater control communicates on the Programmable Communication Interface Multiplex System (PCI) Bus and is fully addressable with the DRBIII(R). [scan tool]

The A/C-heater control's primary means of fault detection is through active and stored diagnostic trouble codes (DTCs). Active DTCs are those which currently exist in the system. The condition causing the fault must be repaired in order to clear this type of DTC. Stored DTCs are those which occurred in the system since the A/C-heater control received the last clear diagnostic info message. DTCs must be read with the DRBIII(R).
Please note that SOME aftermarket scan tools also have the capability of accessing the A/C-heater control system.

A number of Auto parts stores offer "FREE" diagnostic scans in the hopes that you will buy their parts although most have a "no obligation" policy. Autozone .... Advance auto parts are a couple that offer free OBD II scans

The only way to know for sure is to hook up a scan tool that can read live data, then you will know what is turning the light on.

It could be an injector fault or a glow plug circuit fault.
