To anyone who is recently having this issue. I had the same problem with abs/warning lights, And gas/rpm/ Speedo all going nuts. After 4 mechanics and endless stressing. I found an auto electric specialist that determined it was the abs pump/module. Hopefully this helps. I spent hours watching these videos and going crazy. This was my fix. Hope it helps someone out!
I had this problem too. My fix was the big red plug under the #25 fuse had wires that had backed out of the connecter a bit and were not making a perfect connection anymore. I unhooked my battery and pushed all the wires into the red connector with a small screwdriver. This seated them all fully on their pins and stopped my electrical gremlin. I made a video of it here. Hope it helps. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DK_trGx2_fQ.html Hopefully RU-vid will let me post the link.
I had a similar issue and found that one of the ECM connectors was full of motor oil. The cause was a leaking oil pressure switch, and the oil slowly wicked its way up the wiring into the mentioned connector. Cleaning all of the oil out of the connector fixed this problem for me, going on eight months. The video I made showing these findings is linked below. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-oGAfw2xpucU.html
