My 2005 Ford Freestyle Limited keeps having the Check

Customer Question

My 2005 Ford Freestyle Limited keeps having the Check charging system light come on and off. this has been happening now for about 14 months. Everything checks out with the alternator and battery. Seems it maybe the voltage regulator. Is that located in the PCM and can it be easily replaced.?
JA: Does the battery look like it's leaking? And does it have a strong smell -- like sulfur? What confuses you?
Customer: New battery
JA: Are you fixing your Freestyle yourself? What have you tried so far?
Customer: Yes I have not done anything. the car runs fine except for the pesky check light.
JA: Anything else you want the mechanic to know before I connect you?
Customer: No

Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

Expert:  rpmdiag replied 3 months ago.

If the alternator is indeed good and the wiring is too, then the computer has failed due to the voltage regulator inside of it.

Thanks, Ron

does the entire PCM need replacing or is it a component . Places like Ebay have regulators that supposedly fit it
Expert:  rpmdiag replied 3 months ago.

No, the part is inside the electronics of the PCM. it has to be replaced and the new one will need to be flashed with a scan tool.

Thanks again and please remember to rate me 5 stars and keep this link in case you still need me again later on. I'm sorry this happened to you, but this is just the way they build these things nowadays.
