Hello. Suddenly at work my remote key stopped working. I thought the battery would have ran out. Later that day I wanted tot drive my car but when I started it. It gave me multiple warnings. Fuel level sender fault, oil pressure low, fuel and oil gauge on zero, traction control permanently off, handbrake on. Lights, blinkers, brake light, ac, radio also stopped working. I figured it might be water damage to the sjb. I opened it up and checked for corrosion or watermarks but I found neither. I checked female connectors and those also looked fine. Checked and cleaned all fuses in both fuseboxes. Removed aftermarket radio. After resetting by removing battery terminals nothing changed. Battery and alternator seem both fine. 12.7 battery, 14 volts with engine on. I started looking for bad grounds. I dont have a scope to check CAN interruption. Anyone who can help me out here? 2006 4.6 mustang gt.
