Had the yellow light with parking brake fault written. Using scan gauge 2 I got no codes found or pending. Removed negative from battery waited 10 minutes started vehicle pumped brakes and pulled up on brake swith and the brake released. Putting car into gear and drove a few feet then placed into park the parking brake did not engage which I believe it normally does. I am able to engage the brake on and off by the parking brake switch. At the current time to prevent another locked up parking brake I am holding the parking brake switch down as I turn off the car and pull the key out which seems to prevent the parking brake goin on. Any suggestions to get this back to normal would be appreciated. Also my battery is brand new. TIA

 

I'll do my profile next. Thanks for your patience

 

Pulling up on the lever engages the EPB not releases. Has the warning gone away? Does the brake work normally now?

 

Thanks miKey for your interest. The light is out. I'm able to engage and disengage the brake the only thing it does not do is to engage the parking brake when placed into park. Do you know if I need a special scanner to pick up dtc's for the parking brake module. I have a scan gauge 2 which supposedly reads all makes but when I scan the car when the light was on and it read parking break fault no codes where found. I know there's at least 8 dtc,s for the parking brake in the manual I have.TIA

 

Mine doesn't engage when put into park until you switch engine off & remove key.

 

I will look into that I believe your right. The cars my wife's so I hardly ever drive it until she tells me there's a problem . I need to read this mitchel online manual I bought the other day. This vehicle has a lot of electronic systems. I appreciate everyone picking up my mistakes. It appears that the parking brake system seems to be functioning correctly now. I'll just wait to see if it locks up again. Do you know whether my scan gauge 2 should be able to pick up any dtc's. I found it hard to believe that with that yellow light and the words parking brake fault that there wouldn't be any codes . TIA

 

Should be codes in the EPB module which that tool's software will fail to read I expect.

 

I've had the EPB fail come up momentarily only to disappear with no other issues. Have you looked to see that the trunk/boot floor is bone dry? A bit of water is not rare and drives the computers nuts.

In your posts above, it's not clear if the brake actually failed to release or not at any time, or there was just a warning.

 

I suspect low battery when it happened.

Probably an unmaintained EPB as well.

 

I think the battery also. I was having lots of EPB problems and my battery seemed fine even though it was the original. I replaced the battery and no EPB problems since, coming up on two years now.

 

The battery is brand new but I'll multimeter the battery. It was interesting what one of you guys mentioned water because my wife said the trunk had accidenly opened on here while parked in our driveway and it was lightly raining so even though it's been a few days I'll check the trunks bottom. The brake has been working fine last time I checked but we don't drive the car daily. Tia

 

Trunk is dry didn't look like any water was in there. Battery is 12.30 volts which is about right. The only thing it's not doing is setting the brake when I turn the car off after placing it into park. I can use the brake switch to engage or disengage. Now I did the procedure of holding down the brake switch while at the same time taking the key out this was supposed to prevent the brake from engaging when I shut the car off and I did this in the beginning of the problem so my wife wouldn't get stuck somewhere. According to what I read the disabling feature is suppose to be reversed once I engage the car back into gear the next time I would start it. So I' m not sure if something's wrong or if I've disabled that feature. If the latter I need to know how to reset the brake? Tia

 

12.3V is questionable - should be in the 12.5 to 12.6V range. Getting the battery to this range might be key.

If your not using the car often - consider putting a trickle charger on the battery (I personally use C-Tek)

As far as disabling/enabling the EPB - it can be accomplished via dealer level diagnostic equipment.

 

And?

 

Yes the brake actually locked up but so far it's been working. Thanks for all the guys who helped me. Happy holidays.

 

Same thing happened to my car today. I am going to try disconnecting the battery, see if there's water in the trunk, and any other suggestions I should do? I have to wait till tomorrow morning if its not raining but i found your post very useful and down to the wire of whats going on. I appreciate that.

 

Check voltage engine off, after standing over night. Should be 12.5 or more.

 

abonano, does this mean a mongoose can disable the EPB and if so will there be no message on dash?
Thanks

 

hi, I don't think any level diagnostic software can permanently disable the EPB. I'm not sure if Mongoose can access the EPB. I know WDS/IDS can access the EPB
