PMIII TROUBLESHOOTING MANUAL?
« on: February 14, 2016, 07:42:37 PM »

Anyone got a manual/guide possibly pdf format?

I'm reaching, but if anyone would have one it'd be one of our members.

Just the factory manual for the car.  I've seen the PMIII book pop up on eBay once in a while.

I have the factory manual and a PMIII training manual. What specifically are you dealing with? Note that if you post on w-body.com you're likely to get more replies in general. I often forget to login over here since the board is so slow these days.

Well beyond my immediate issue at hand, I'd love to have a copy for reference. Wondering if anyone's got it in pdf yet.

What it's doing is odd. I know I need an accumulator ball, mines way low. However, I may have another issue. You hit the brakes slowly they remain unboosted until the pedal is half way down, sometimes more. Then after about 4-5 seconds of holding the pedal at that depth, it will finally "boost" my brakes and throw you through the windshield if your not careful. At that point you have full brakes. Until you release them of course.

Worked fine since I've got it, this just happened out of no where.

That could be a symptom of the accumulator.

Well does anyone know of a suitable replacement accumulator P/N?

Sure it's been asked a thousand times but my internet search time has been limited lately to say the least.

I would not think the lack of boost until the pedal is so far down would be accumulator related. I've had a bad one before and besides longer run time and more frequent running the system acted like normal. Now I do not know how discharged the old accumulator was because I did not have a pm3 brake pressure gauge to test it back then.


Which of the warning lights are lit on your car and do you have a scan tool to pull the codes related to them?

I get alot of excess run time and the lights vary. Sometimes i'll get a flashing antilock, sometimes it's solid and sometimes it's simply off. This sudden "delay" was spontaneous with its initial appearance, meaning I had zero issues with the unit (other than the pump running alot) and then wham. Everyday, every time. Gotta give yourself like 5 extra car lengths. But the other day I slid in some driveway gravel, and lo and behold the pedal chattered and the unit worked perfectly and stopped me right there.

So it's intermittent. I'm sure I need a brake fluid flush but still. It won't boost the brakes until way to late. Anyone but me would end up in a ditch.
