Frequently asked questions about U025E
What does U025E mean?
Lost Communication With Electronic Brake Booster Control Module A. The control module stopped receiving expected network messages from the Electronic Brake Booster Control Module A node on the vehicle communication bus.
Is U025E generic or manufacturer-specific?
U025E is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove U025E 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 U025E is removable in your case.
