Turning off MIL codes

[soffenbecher]

I have a 1994 Ultra jet boat running a 5.3 LS1 engine. I am using the stock ECM and am wondering if I can zero out all of the MILs' I don't have an indicator light on the dash so these just kind of show up when I do a scan if there is a in the circuits.

You can set the MIL to "No error reported" for the codes that do not apply to your application. I would still keep the codes that could help you diagnose something down the line, even if you don't have an MIL light, you can still use a code reader to retrieve them.
