Yes they can test it

 

An auto store will do a test, for sure. Its value will depend on what sort of tester they have. Pass / fail will not tell us much.

Do you have a digital volt meter? If so, please let the car rest over night and then measure the battery voltage before starting the car. This will tell us a lot.

What you reported earlier says sensors are OK. But we could have some intermittent connection to one or more of them.

Not sure what sort of pump sound you're listening for ...

 

Dennis, I will check the voltage when I get home and report the readings. As for the pump, was wondering if you could feel it running with your hand on it. Just a thought, does the pump run with just the switch on or does the engine need to be started before it runs.

 

Gus, you stated that you had recieved the error while parked, what was your findings as to the cause ?

 

OK, so you drove a different car today, yes? We want a reading after the battery has been at rest for at least several hours.

As I recall ... the ABS pump should not run at all with the car not in motion. It first kicks in when the car reaches some set speed ... a few miles per hour. Maybe somebody can double check that answer, please.

 

It was my 95 xj6 and the cause was the ABS control unit. Replacing it was the only option at the time…

 

Dennis/Gus, I took the voltage measurements when I got home. I read 12.38 when I got home and 14.10 when I started it it, and had a battery date of 8-11.

 

I'm sorry but I still don't know if you drove this car today, or another car. Either way, that not a good voltage number. It's a very weak number if you did drive this car today.

So with this fresh info, maybe it's best to focus back on the battery as a possible culprit. Can you take it to a shop and have someone confirm the measurement? (If they want to do a load test, couldn't hurt I suppose, but confirming the voltage number is top of the list.)

If the battery voltage is really 12.38 shortly after the car is shut down, I'd try charging it and then if that did not improve things significantly, I'd replace it.

 

No I did not drive the car today. I haven't drove it for awhile(car in limp mode) but have been starting it and letting it run for 10 minutes or so each day while I check things out. I'll do that and put it on a charger for a few hours and check the voltage. What would you say is a good # on the battery @ charge.

 

I'm sorry, my head is shot tonight and I'll need to review the thread to remember where we are. I seem to have confused two separate cases. Back to you tomorrow.

 

OK, so FWIW here are my somewhat disorganized thoughts about your situation.

Car in Limp Mode: I did not catch this before your most recent post. This changes everything, and such being the case, I would put ABS issues on hold for now. Bigger fish to fry. I don't have the knowledge to advise you on addressing the Limp Mode condition.

It's not a good idea to run the car for a few minutes each day. When you do start it, it should be allowed to get nice and warm. You'll also need to keep charging the battery manually if you don't run long enough for the car to charge it.

Battery: once fully charged it should hold at least 12.4 V or so overnight, given Houston temperatures. Something over 12.5 V would be best. The way I get to these numbers is shown here.

ABS: I would table this for now. It may resolve itself when the limp mode thing is fixed but, IAC, may be more difficult to solve while in limp mode.

Sorry I can't be of more help.

 

jaysjag, I just checked responses to your original post, and don't think anyone asked which three fuses do not have power. Can you identify them, please?

RJ that turned out to a non issue, thanks for asking. Good news Dennis/Gus is that my abs and limp mode has cleared ??? knock on wood. Drove the car today after having the battery checked and charged and no limp mode, after a few miles I used the reader to clear the abs it never came back, will check tomarrow, keep your fingers crossed that it's not a lose wire somewhere. Thanks for all your help. I've got another issue now, but I will start another post.
