1999 Saturn SL1 Service Engine Wrench

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.

sc1 means saturn coupe with a single overhead cam engine sl1 means saturn sedan with a single overhead cam engine same engine and same parts for both these cars

disconnect the negative cable and let it sit for 5 minutes-hook it back up and let it idle for 5 minutes, then drive it normally for 5 more-resets all sensors, if there is something wrong the lights will come back and you should get a code.

1998 Saturn SL1 5 Speed everything manual except Cruise Control. Run Great. Every time I start it, it goes through it's check cycle and comes back GOOD. But as soon as I move approximately 20 feet the SERVICE Wrench Light comes on and stays on until the car is shut off. This happens every time, doesn't matter if I go forward or reverse. All checks have turned up nothing. No codes. I checked the wiring and have found nothing. I have checked and replaced any and all bulbs, including the ash tray bulb. I have replaced the Cool Fan Relay. And still the problem exist. Any feedback or advice would be greatly appreciated.

Hello. this is a warning indicator. this light is on because there is either a problem with the engine control system, or even possiblity the abs unit. you will need to have the vehicle scanned for trouble codes to see why this light is coming on.

The SERVICE (Wrench) telltale is pulled to ground by the powertrain control module (PCM). When the lamp is pulled to ground, current from the ignition circuit flows through the indicator lamp, allowing it to come ON. The PCM will turn the SERVICE (Wrench) telltale ON for all non-emission related DTCs that require that a telltale be turned ON (some DTCs do not turn on a telltale but are stored to aid in diagnosis).
The SERVICE (Wrench) telltale will also be turned ON if the ABS control module has detected a fault in its own warning indicator system. If the ABS system cannot turn on its own telltale, a message will be sent to the PCM through the class 2 data bus (circuit 1807) to turn on the SERVICE (Wrench) telltale.
The SERVICE (Wrench) telltale will be turned ON for 2-3 seconds when the ignition is turned to RUN for a bulb test.

That is in the main computor of the car. The only way to fix that is to change the computor. I changed one in a saturn that had the same problem, put in new computor, problem solved.

the light reminds you to service the engine . A mechanic can or you can turn the light out by disconnecting the Battery.this also causes memory loss in your Radio .

the ses light might just be a speed sensor in the hub, and the wrench means service engine.

could be a blocked cat converter or a trans issue,,,usually a severe problem when the service wrench light comes on versus the service engine soon light, the wrench light means more important problem,,i would take it to delaer

It is a transmission problem and is often solved by changing the fluid and filter.
