Can anyone tell me what this means?. I was driving along in my 2003 discovery V8 auto ES, and all of a sudden there were 3 bleeps, and the traction control, hill descent, and abs light came on. Nothing felt any different and brakes etc, all seem to operate ok. Stopped turned off engine, and then turned ignition back on, it did the usual checks, and all warning lights went out, started up and drove off with no problems. Next day did same again, Does anyone know what might be causing this?, I would appreciate any advice, Thanks.
