well i took off my tachometer and put it back on and then the service vehicle light came on. i took it to autozone and there was no fault code for it. i have 60,000 miles on the car. someone told me that on ls1's u have to replace the timing chain when the car reaches that amount of miles. is this true? has anyone encountered this problem before??

 

In the back of your owners manual it will say the required services for X amount of miles. Either way that would definately not make the SES light come on. Could just be something faulty in the light itself if there is no codes. Was it an aftermarket tach that you took off and put back on, and why did you do this? Could help answer the question better for others.

 

its the same tachometer. i took it off cause one of the lights that light up the tachometer was out i needed to replace it. i dont have an owners manual

 

He's talking about the service vehicle not the SES light. 2 different things. Autozones scanned for SES codes thats why they didnt read anything. I have the same like come on intermitently. Dont know why?

 

I had it for a long time too. Mine turned out to be codes turned off in HPTuners setting off the service vehicle codes. Koolrayz you doing Norwalk rental again 9/18/06??

 

HELL YES That was a good rental. Are you going to thunder in the north this weekend at dragway 42?

 

I may go to watch but my car is on blocks, awaiting parts.

 

Ahh, thanks for clarifying that. I'm not sure i've ever even saw the service vehicle light.

 

Hey 99 camarosupersport how many miles do u have on ur car?

 

The service vehicle soon light comes on because of BCM/electrical problems.

Dealerships can read those codes or anyone else that may have a Tech 2.
