Frequently asked questions about U1403
What does U1403 mean?
Diagnostic Trouble Code (3 interpretations). The control module judged the Fuel level, serial communication signal implausible when compared with other operating data. This is the manufacturer-specific definition used by Chrysler.
Is U1403 generic or manufacturer-specific?
U1403 is a manufacturer-specific code. In this database it is documented for: Chrysler, Dodge, Jeep. The same number can mean something different on other brands.
Can TuningBot remove U1403 at file level?
Not guaranteed. Powertrain (P) codes can be reliably disabled in the ECU calibration, but body, chassis and network codes depend on the specific control unit and how the fault is implemented - some can be handled, some cannot. Ask for a quote and our engineers will check your file and tell you, free of charge, whether U1403 is removable in your case.
