    I think your are mistaking me for the engine service light. I am not getting any codes the light that comes on is the service light with a wrench symbol next to it, the abs and the airbag light. does the bcm have anything to do with it.

 the service light with the wrench is a secondary light relating to engine sensors headlights and taillights. if you see the engine light (major Malfunction) its a good idea to pull over and find a ride before you do serious damage to the engine.

Hi and welcome to FixYa,

Initially, it would appear that the Saturn have multiple issues going bad simultaneously of right after one another. This would be very rare and the components are indirectly related so therefore should not occur. Not unless, the BCM (Body Control Module) is the one at fault. The BCM is akin to the ECM. Whereas the ECM (Engine Control Management) is responsible for the operations of the engine compartment, the BCM on the other hand is responsible for the operations of all others inside the vehicle including those that you described. The BCM would look like the image below and often mounted on the back of the glover compartment and or under the dash.

Offhand, you could try locating it and making sure that the plugs and connectors are tight and secure. Other than that, there are no easy user fix except replacement. I am not fully aware of any recalls related to this, however, I understand that there were several Technical Service Bulletins (TSB) informing dealers and mechs the need for the replacement of BCMs of certain years/models.

Good luck and Thank you for using FixYa. Happy Holidays.

You need to scan the car to see what codes come up, let me know what comes up you will have to take it to a shop to get it scan. the abs light could come on if the brakes fluid level is low or if there is a problem with the hydraulic system for example this could mean a bad proportional valve. good luck keep me posted happy holiday.

Hello mardilove92

take it to a local auto parts store and have them check for codes. They should do this for free. Let me know what codes they get and I can let you know what to do.

HI I HAVE A 2002 SATURN L300 AND I HAD AN OIL CHANGE TO STOP THE WRENCH LIGHT FROM COMING ON AND ITS STILL ON WHY IS THAT? I THOUGHT THE WRENCH LIGHT WAS ONLY FOR MAINTENCE. THANK YOU


If you reset the monitor when you had the oil changed, and that light is for oil change due, the light should have stayed off.
Usually the wrench warning light is a service vehicle warning, not for oil change is due.
Your owners manual should explain each warning light.
You may have to get the body computer checked out by a shop or the dealer.

My Saturn L300 2002 has the wrench service light come and it drives good


You should be able to have an auto parts store check the engine computer for trouble codes. The codes would direct a mechanic as to what to check next.

Service light w/wrench


Sound like your Throttle Position Sensor (TPS) has an issue. Check the wire leads first and if that is good, replace the TPS. A faulty TPS will give you a hard 1-2 shift and delayed shift on the higher gears at WOT. Good luck and keep me posted, be glad to know your car is running 100% again.
