Is there a way that I can get the PCM tested to see if it's good or bad? After I replace the alternator two days ago I have not came across the issues that I was having but I would want to go ahead and get the PCM tested just to make sure.

well you could go back to Autozone and have the scan the car's computer--they'll probably do it for free; otherwise, if your charge light isn't on, I'd just see what happens. As I said, rebuilt units from chain stores are a dodgy thing.

My car does not have any check engine light on at this time and Autozone will not be able to check it. It might be just that the alternator was bad... if it was then I learn my lesson for next time... but I will be take it to a shop to make sure that the pcm is good just to be on the safe side.
Thanks a lot Mr. Shiftright for helping me out.
 
Thanks you

Oh i don't think you have to do that...if the PCM weren't functioning, you'd know it. You might have the shop check all your battery cables, connections and ground cables however. You see, when the voltage drops, for whatever reason (bad battery, bad alternator, bad connections, etc.) your car's computer goes nuts---so we can't say with any certainly at the moment that the PCM was actually doing something wrong. It does, however, control the charging rate.

#154 of 197 ABS Module Failure by mach1girl

Aug 11, 2010 (10:01 pm)

I have a 2004 Mustang Mach 1 and the ABS Module has internally shorted out. Replacing the ABS Module looks easy enough, but is there any re-programming required? If so, what needs to be done?

#155 of 197 2001 ford mustage V6 3.8 electrical problem by moyo71

Aug 13, 2010 (2:04 pm)

I have a 2001 V6 mustage and everyonce in a while the radio cuts off and the oddometor goes dim then back to normal when i have the headlights one. The headlights dim the first time. I changed out the alternator from autozone and a month later i had the same issue. I replace the alternator and now a month later it is doing again. i had a friend take a look at it and he did a quick check on the ground from the engine to the body and it was good. i took the car to ford and they checked it out within an hour and they stated that the ground is good. they told me to bring the car in when it happens again. I do not have any check engine light one. i have 150,000 miles on my car. somebody told me that it may be a fuse but if it was a fuse the system would be off. i was thinking about replacing the headlight switch hoping that they may cure the issue but then i was thinking that it might be a grounding issues. I still have the orignial radio in the car. about a year ago i had the dome light that would stay on after the car was shut off. i when ahead and remove the dome light bulb could this somehow be related.
