Post subject:  Liberty CRD- low oil pressure lamp, inoperative fuel gauge,
I have a 2005 Liberty Diesel with a build date of 2/05. After hitting a substantial hole in a parking lot while pulling a boat (coincidence ?) the low oil pressure lamp came on as well as the A/C quite working and the fuel level gauge quite working all at the same time. Seeing these all run through the Front Control Module I started by connecting a known good ground (battery) to the module ground and tested the 5v reference, which is .4 volts at the FCM and the ASD supply voltage. which is 11.6 Volts at the FCM. I was ready to replace the FCM until I read a post stating that they replaced the FCM and still had the same problem. I followed their thread to the best of my ability but could not see what the cause and correction was. I have not checked the wiring harness since the voltage supply and grounds seem to now be within reason (checking them at the FCM) and not showing the 5 volt reference. Any ideas, I know there some really sharp people on this site and it seems like this might be a common problem starting to appear on these

I'd start by checking all your fuses on the interior driver side fuse block.
In another post someone had a similar problem. I think they said it was fuse #14.

I have this exact same issue but with the addition of the water in fuel light also. I haven't found a solution yet but still drive it every day. I just watch the odometer to know when to fill it with diesel. All my fuses are good, no codes, AC will work randomly.
