engine and abs lights coming on ???? - 10/8/2006 10:56:14 AM    kirby75   Posts: 2 Joined: 10/8/2006 Status: offline i have a 93 astrovan 4.3. the abs light and the service engine soon light go on and off intermittently. i have the code reader and it tells me that the ecm code is "#43 electronic spark timing (EST) circuit - low voltage detected / electronic spark control (ESC)- circuit problems". and the abs fault is "#8 shorted dump valve circuit or faulty ecu". both these lights started coming on within a day of each other...i kinda sounds like maybe something is not putting out enough voltage or something. any ideas what it could be??... thanks Post #: 1
