86-89 Digital Instrument Cluster "OD" light |
Subject: 86-89 Digital Instrument Cluster "OD" light by Woodstock on 2012/12/8 16:50:14 Hi Gurus, for an 88 automatic I wrote an 89 automatic Eprom. Never had a problem with 86, 87 and 89 Vettes. In this 88 the "OD" light comes on, which has never been seen before. What causes the "OD" to come on in the first place? I this a sign for trouble or some sort of service light? With the original 88 Eprom the light stays off, with the 89 Eprom it comes on right away, even without starting the engine. I don't really know what to look for in the Eprom hack, without even understanding what causes the light to come on. Here's a pic: |
