I have a 2004 s10 blazer, for some reason my E/parking brake light along with the abs light will not go away, it also has the service engine soon light on. During the time I have been trying to fix these issues my I found out that my battery is being drained. I just replaced the alternator, battery, and breaks.. Any help or suggestions would be greatly appreciated!!

 

Check and make sure you aren't low on brake fluid, that will also cause that light to come on.

 

Not equipped with a low fluid sensor.


Usually when that happens, there's a fluid leak in one of the lines. The centering valve shuts off the failed hydraulic system, and turns the dash light on. Is there too much free travel when you apply the brakes, (low pedal)?

 

It`s best to have someone run a scan test for the abs system.My brake light/abs light hasn`t shut off since I bought my blazer 6 months ago.I took it to my mechanic that I`ve been doing business with over 20 yrs.I told him my problem, he ran a test and found out the abs module was defective.With the abs modules, 9 out of 10 times you can re solder all of the solders you see.Or you can just buy a new one.That was my problem ,but in your case it maybe something else.Make sure your have the brake fluid to the full line in master cylinder,make sure the parking brakes are off, check the ground wire running from the abs to the radiator area.There more parts involved i`ve never mentioned, that`s why it`s just easier to run a test.As far as the engine light on,run a scan on that too.Whens the last time you`ve changed out the O2 sensors?I had an issue with my engine light on.I changed out both of my 02 sensor,engine service light went off.
