U110C lost fuel level message. is this something to do with the pcm
Hi Anonymous, Im glad to help!
The U110C is a BUS Message and usually has to do with both PCM and BCM, because its a lose of BUS Signal between the PCM and the BCM.
FIRST THING TO TRY:
The first thing I would try is remove the negative battery cable for 20 seconds then replace it. NEXT: Start the engine several times then let idle for 10 to 20 minutes then start it several more times and if the code doesn't return and the check engine light stays out, simple drive it for awhile like you normally would. If the code come right back, below is some common problems.
COMMON CAUSES of U110C:
(1) Communication with BCM is lost / See if you can communicate with the BCM.
(2) PCI Bus Circuit open between PCM and BCM / Check the positive and negative bus signal at both the PCM and BCM.
(5) Fuel Level Bus Message is missing
Obviously, all these issues must be tested to see which one is causing the problem. BUT first try the battery cable removal and see what happens.
Let me know the out come and I'll try to help further.
Hope this helps and have an awesome day!
