traction control light stays on. on 2003 Cadillac DeVille

not often but is bothersome since we don't know if this an emergency problem or can be ignored. Local mechanic suggested we put a piece of tape over the light.

have codes scanned in traction module
Is this an urgent matter to be concerned about? We are on vacation in Michigan and won't be back in Iowa until Monday.
