Do you have a number when I can reach you with mores details please? Measure resistance between negative battery terminal and Power-To-High Speed Fan circuit terminal at cooling fan wiring harness connector. If fan operated at one fan speed, go to step 50. If fault is not located, problem cannot be duplicated or identified at this time. If voltage is less than 10. When I get the engine started it runs great, plenty of power, no hesitation, just great.
If that doesn't work, probe the relay socket with a 12 volt test light to see what's going on. Leave scan tester and test light connected. Test light should be on. Cannot be duplicated at this time. That's why I said it's a ford proprietary code, so I looked on my Ford discs, and that code isnt in there. If resistance is less than 5 ohms, go to next step. When purchasing a replacement module, pay attention not only to the model of the vehicle, but also to the trim level that the particular part supports.
Check for indication of fault test light blinks or comes on while performing one of following:? Procedure skips from step 190 to step 195. Following are possible causes for this fault. I run a jumper from spark tester to negative battery terminal. Access Output Test Mode on scan tester. What size engine do you have? If resistance is less than 5 ohms, go to next step.
If voltage is less than one volt, go to next step. No test procedures have been omitted. When you took a spark plug and put in plug wire and touched to a good ground? Reconnect all components and recheck system operation. If resistance is less than 5 ohms, go to next step. While I still had the key in the run position, I ran codes, it wouldn't read anything.
You can remove the module and take it to a parts store and have it tested, you will need a 5. Command High Speed Fan On. Procedure skips from step 70 to step 80. Measure voltage at breakout box test pin No. If fault is not located, problem cannot be duplicated or identified at this time. When you turn key to on position not start position do you hear fuel pump run for a few seconds? Measure voltage between breakout box test pin No. Possible causes are as follows:? This intermittent problem must be in a wire or connection? Measure resistance between terminal No.
No test procedures have been omitted. Measure voltage between test pin No. Test light should be off. If fault is not indicated, problem is intermittent and cannot be duplicated at this time. Procedure skips from step 111 to step 115.
Repeat voltage check and note voltage. If all voltages are 10. No test procedures have been omitted. That I know it doesn't do normally. If voltage is less than one volt, turn ignition off and go to next step.
Terminal numbers are molded on relay. No test procedures have been omitted. Connect voltmeter negative probe to negative battery terminal. The 2 hot terminals should not light the light at all. This is all political in nature, and you either know that or you are simply stupid! Relay for the Air Conditioning clutch on the compressor. The module is mounted on the right hand side driver's side of the frame.
Terminal numbers are molded on relay. If any reading is one volt or more, locate and repair short to power in Power-To-Low Fan circuit or Power-To-High Speed Fan circuit. I have checked for spark when cranking the engine before the fuel pump shuts off. No test procedures have been omitted. Connect a non-powered test light between cooling fan wiring harness power circuit and ground. If voltage is less than one volt, go to next step. If fuel pump cannot be heard, go to step 173.
