Cadillac srx northstar: I purchased a used 2004 srx northstar.

Customer Question

I purchased a used 2004 srx northstar. It runs great. However the traction light, check engine light abs light come on after about three or four miles. I have the codes pulled and it shows no problems. do a reset and the same happens. Would this indicate a ecu starting to fail?

Hello, my name is***** for the question. If I am not online when you return please give me some time to get back to you. Can you tell me if all of these lights come on at the same time? Did you try pulling codes with a generic scan tool?

yes using a scan tool and two programs on the laptop with elm327

All at the same time

Is it showing communication with the modules? Can you see live computer data?
Customer: replied 1 year ago.
it connects shows no codes but will not show live data

It sounds like the computer may not be communicating with the car properly. If it is then you may have an ECM problem or possibly a voltage issue. If the battery is failing or if the alternator is not charging right then these lights will all come on at the same time.

I found the problem and it now has no lights or codes. It was the right front wheel sensor. I replaced the hub and all lights went away by themselves. It has been run 100 miles and no problem.
