Sometimes as with mine i had to take it to the dealer or a trusted mechanic and have him hook up the diagnostic computer to clear it. it will tell him what is wrong with it too. mine was the catalytic converter. it will keep coming on if car is not fixed. i took mine to the dealer and it cost $1200.00 out of my pocket. find someone else if this is the issue and have them only cut off the catalytic converter and only replace that part. much cheaper only cost me $300.00 parts and labor for my 2003 yukon xl.

Sometimes it will reset if the battery is disconnected, but most likely it will need to be cleared, before its cleared, read the code and write it down, along with what the code means. then you can determine if its OLD or a NEW code. if it comes back you can check further,

What does it mean when service engine soon is on in my 99 jimmy?


Not related. The service engine soon lite is operated by the speedometer, so it's just coincidence that it came on soon after the water pump repair.

Service Soon light is on.. what does that mean?


In most cases the light will go out by itself once the problem is resolved that made the light illuminate. You can RESET the light by removing and re-installing the fuse(s) marked as ECM in the fuse panel or by disconnecting the battery for several seconds.

If the light continues to illuminate, You will need to extract the computer codes from the computer via the factory specifications to see what code(s) are being stored in the computer.

NOTE: Disconnecting the battery will cause the engine to run a little erratic until you drive it for several miles so the computer can re-learn it's proper settings.

Service enj soon lite


Try resetting the computer. Disconnect your battery for 5-10 minutes and reconnect. This should get rid of the light if the gas cap was the problem. If it comes back on take it to an Advanced Auto or Auto zone and get an Engine Diagnostic, they're free. Hope this helps
