Today my 05 EXL had the wrench light come on and beside it showed that oil life was at 15%. There was also what appeared to be a code to the left of the oil indication that had a 3 with a small B above and to the left of it. Does anyone know what that means? When I pushed the button on the dash and acknowledge the message, the wrench light went out, but the code and the oil message remained. Any information? Thanks.
