Help! Battery died, charged battery now getting all sorts of error codes!
 

So my battery died today, so I put on an automatic charger for a couple hours. Told me fully charge so I disconnected the charger. When I start my car, I'm getting all sorts of error codes?

Do I just need to reset something? Or did I screw something up?

If you have obd scanner reset codes with that.

Else remove barry negitive terminal, press brake to bleed off any residual power, reconnect battery terminal.of ok your good if your srill getting codes its likely battry is still suspect check volts and read codes.

So unfortunately I can't find a socket that fits the bolt holding the negative cable....but I did pull the ecu fuse and the codes are still showing? So I'm guessing time to see the dealer...fck...

My battery died 15 month after I bought the car. I got it replaced under warranty.

DANG.......jermyzy ....... borrow a wrench ..... :sigh:

Then, I suggest you do what @steve99 suggests.

Also, you may wish to check the voltage this way (borrow a voltmeter):

While you're messen with it, you may wish to clean the battery terminals.

If the battery still acts up, I suggest you have it "load tested" at a shop.


As you know, this is not a good time of year to have a weak battery ..... especially in Canada.......:eyebulge:

That was most likely caused by a bad throw out bearing ........ :D

Have you guys been checking the fluid level in the cells? The OEM unit is a conventional battery requiring periodic maintenance. It WILL boil off.

Technically, outgas as molecular hydrogen and oxygen through electrolysis but, meh...

potayto-potahto

So you guys are saying all the warning lights are battery related?

No. I'm saying take care of your battery and it will live a long healthy life. Neglect it and it probably won't last much longer than 15 months.


...give or take. :D

Not all of them are "directly" related ....... but a bunch of them can get confused, if the battery gets weak or goes dead.

By disconnecting the battery, it gives the system a chance to "right" itself.

Codes can be "erased" by most code readers, although they may come back, unless the root cause is fixed.

Inexpensive code readers can be purchased at most auto shops ..... a code reader is a good tool to have.

In addition, without going "all chemist", if you add water to the battery, use ONLY distilled water.


Why? Ask ol @Ultramaroon ..... he will give you the answer at the molecular level ...... :thumbup:

Trying to see if any of my family has a 10mm wrench...it's 11pm here :(

Update, took it to the dealer and yes, all the codes were being thrown because of weak battery. Switched out for a 600cca battery, hopefully I will be able to start my car in the winter reliably now, lol. Also apparently I installed two of my winter tires backwards, oops!
