Code U110C Chrysler Description

The U110C Chrysler code indicates a lost fuel level message, meaning that the vehicle's onboard computer system is unable to communicate properly with the fuel level sensor. This can lead to inaccurate readings of the fuel level in the tank, which can result in various issues related to fuel management. The fuel level sensor is responsible for sending data to the ECU (Engine Control Unit) to ensure the accurate display of fuel levels on the dashboard. When this communication is lost, it can lead to incorrect fuel level readings, impacting the driver's ability to monitor fuel consumption accurately.

Tech Notes for U110C Chrysler

The Powertrain Control Module (PCM) continuously monitors the fuel level from the Fuel Level Sensor through the Body Control Module (BCM). The U110C code indicates that the PCM lost fuel level communication from the BCM. Start by checking the PCM and BCM harness connectors, retighten the connectors, and clear the code. Also, check the battery charge, as a low battery charge has been reported to trigger this code. If the problem persists, replacing the BCM will be necessary to repair the issue.
