Frequently asked questions about U2003
What does U2003 mean?
Diagnostic Trouble Code (11 interpretations). The control module detected the fault condition "Not -characterised" for the Coherence fault between the status of the vehicle and the main controlled triggering request received by the CAN. Documented for the AM6/AT6 automatic gearbox ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models.
Is U2003 generic or manufacturer-specific?
U2003 is a manufacturer-specific code. In this database it is documented for: PSA. The same number can mean something different on other brands.
Can TuningBot remove U2003 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 U2003 is removable in your case.
