Frequently asked questions about U1113
What does U1113 mean?
Diagnostic Trouble Code (8 interpretations). The control module detected that the expected Automatic gearbox communication fault with ABS ( ESP) was absent. Documented for the AL4 automatic gearbox ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models.
Is U1113 generic or manufacturer-specific?
U1113 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 U1113 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 U1113 is removable in your case.
