Will you be able to reset the codes and start from there as it shows. Meaning that there might be some immediate codes that need to be addressed and the rest might get cleared away.

 

i already tried it a few times with the obd reader with a snapon reader and disconnected nothing works any other advise?

 

Reset the codes, and then check your battery voltage, both engine off and engine on.

Your engine off voltage should be somewhere in the neighborhood of 12.6v, and your engine running voltage should be north of 13.8v.

If you're lower than 12.0v engine off, your battery is likely shot. Lower than 13v running, your alternator is either not charging, or on it's way to not charging.

 

Ok, once you reset the code, those codes should pop one at a time but not all. It need to cycle few times to get all those at once. I'm just saying that once you get the SES light on, there should be some pending codes still getting ready to tell you they are coming and ready screw you more. So, reset and wait until you get codes again or even the pending ones.

 

x2 on clear the codes first. See what comes back.

 

Check to make sure that the ground strap at the back of the drivers side head to firewall is secure and the one from battery to body to alternator bracket is secure.

if these 2 grounds are not in good shape that could be a majority of the codes.
