Service Engine,Abs, and Trac off light came on at same time

Hi there,

I was driving my 2003 Alero the other day when suddenly my service engine, ABS, and Trac off light came on. I check the fuses and there was no bad ones and I looked under the car for any loose wires or anything like that. Can someone please help me out!

The wire may have come loose, have you had your bearings replaced recently? Either way, I had the same issue in my 99 olds and the wire came loose after I had the bearing replaced. I would check there first seeing that it is probably your cheapest route

Hi, there I solved it myself turns out it was the driver front Abs sensor. the bearing had to be replaced because the Abs sensor is build into the bearing.

Service engine light with trac off come on, but while driving lost power had it towed. home . starts but runs ruff. also service light was flashing now on all the time


There is nothing new there, you should
not know what to do about

You do what everyone has done for
over 30 years. Check for codes &
diagnose the system with a fault

You need a professional scanner, thus a repair
shop, to access the ABS Module for codes

The ABS lite, No Trac Lite and Service engine lite keep coming on


When the Service engine soon, ABS and TRAC lights are turned on at the same time the computer control units for the engine and the ABS/TRAC systems has sensed a fault in the electronic controls of the engine and/or the emission system and the ABS and Traction Control system (part of the ABS system). When this happens you will seldom feel the car engine run any different or the car drive any different. There are about 200 possible faults that turn the Check Engine light on, the fault in your car is likely a part called the VSS sensor to know for sure what the problem is you must have the system tested; Kragen and Autozone parts stores do this testing for free

The anti-lock and trac off lights on my 03 Oldsmobile Alero came on along with service engine soon light. Any idea what might be causing this?


More than likely one or more of your wheel speed sensors is not reporting properly. This is fairly common. If you have the ABS codes scanned it will tell you which ones to look at first. I would check/clean the electrical connectors to the wheel speed sensors as these often are the problem.

The ABS system including pump may be faulty which is quite common. You will have to take this to dealership or mechanic. Either there is a bad pump or a fault in the electrical system

you have a problem known to many alero and pontiac grand am cars you have a bad wheel bearing,this is a common problem with these cars and they will not do a recall on this.you need to have your front wheel bearing hubassemblies replaced its not a bad job can be done by a decent backyard mechanic but a lot cheaper then going to the dealer, just save your reciepts in case they do recall your car for this problem they will reimburse you for your cost. If you have service engine light on, trac. off light and the ABS light on the same time, you may be able to get it fixed my reprogramming the power control module (with updated software calibration).
