NEED HELP!!! ABS & Heater stopped working

My car has been stored for about 2 months, I went out yesterday to start and let the car run for a little bit and noticed the battery tender got unplugged, I get in the car no power so I grab the jump box and give it a jump,car starts right up. I let it run for about 30 minutes at an idle while I get some work done in the garage. I get in the car to back it in the garage and the heater stopped working and the ABS was going crazy, I turned the car off and I hear the motor in the ABS unit running, the key was in the off position. I checked all the fuses,all of them are good. If anyone can help it would be much appreciated. Here is some video of the problem.

I would guess if you charge the battery and check this after it has been charged your problem will go away. BTW if you had a blown fuse the ABS motor wouldn't run at all.

Low voltage causes lots of problems with these cars and 30 minutes of run time on a dead battery is not going to charge it up.

Do you have a glass mat battery? red top or yellow top?

Its a Napa battery. I unhooked the battery and put it on the battery tender. After work I hooked the battery back up, the video is from today and I think the battery was at full charge. The battery tender was blinking green which means it is holding a charge.

Sounds like your ABS module has a supercharger...

Just to verify, can you measure voltage at the battery with a multimeter/voltmeter?


Usually a battery tender or battery maintainer won't fully charge a really dead battery. You need to hook up a really dead battery to a regular charger at a higher amperage rate.

Also the battery tender charges at what rate? 2amp, 10amp, and how many hours did you have the charger on the battery?

And what did you find out today with your battery? Did the ABS motor stop running with a charged battery installed?

Pray that this issue has nothing to do with the jump-start. It could be an issue of low voltage, or...Your EBCM is toasted! $2,667 from the dealer. It could also be a bad signal from a wheel sensor that is over-exciting your EBCM. But this module actually diactivates when switch is off, or speed is < 6 mph.

If this prevents you from driving your car, you can simply disconnect the EBCM and tape the connector to protect it, and fix it whenever you can later. All you'll lose is your ABS and the Traction Control will always be off. (Be aware, it's just my opinion and taste. I've driven a goat like this for a couple of months, and I locked my brakes once during that period)

Good luck!

Diagnostic trouble codes. The car cranks but no start right? Check spark and fuel pressure see what they are like.

No, It stopped cranking. It's making a clicking sound like it has a dead battery.

Would that cause every thing to go crazy? I picked up a meter and I'm going to check to see if everything is getting 12 volts.

I had a bad cell in an old car battery once, and it made all of the lights on my dash go crazy. Engine wouldn't crank either, it just clicked. Installed a new battery and everything went back to normal.

I see that you've installed a new battery yesterday, so I'd check the terminals to see if somethings wrong or grounding-out somewhere.

Car sitting for a long time this is what I would do first. Get a known good battery and troubleshoot from there.

You also might want to check ALL YOUR GROUND POINTS. If you have a ground point that has come loose, or developed a load of corrosion this could also cause things to go into stupid mode,,,,,,,,,,,,,,

I checked all the fuses with the car running and off, With it off every fuse was reading 12.4 volts and with it running everything was reading 14.6. I am stumped so I think it's time to talk to my tuner and see if he can figure it out.
