on 1999 Acura TL

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I have looked in the 1999 owners manual and there is NO mention of the CHECK light


got a p1259 code where is this located on the vehicle ?

Thank you

Have you looked in the section that mentions 'emissions' or 'malfunction indicator lamp' maybe? Warning lights.
