check engine light came on, mileage on odometer disappeared? on 1998 Lexus ES300

What could be the problem? The mileage shown on the odometer disappeared first then a few minutes later the check engine light came on. Mileage reappeared minutes later and has now disappeared again. Would greatly appreciate your help. Thank you......
