Frequently asked questions about U1000
What does U1000 mean?
Diagnostic Trouble Code (11 interpretations). The stored code identifies a fault of the Communication fault on the CAN between the automatic gearbox ECU and the other ECUs of the network. Documented for the AM6/AT6 automatic gearbox ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models. PSA documentation does not characterise the failure mode further.
Is U1000 generic or manufacturer-specific?
U1000 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 U1000 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 U1000 is removable in your case.
