You do need a dealership for initial diagnosis. With a multimeter and a basic OBD-II scanner (capable of reading manufacturer codes), you can pinpoint the issue.
Scan all modules. B23A0-92 often appears with P0562 (System Voltage Low), P154A (Battery Current Sensor Circuit Range), or U0168 (Lost Comms with BMS). Those companions help narrow the cause.
In the automotive diagnostic world, code combinations can sometimes look like a rare classic engine serial number. While a novice might mistake for an obscure 1992 variant of Honda's legendary B-series or H-series engines (like the 1992 Honda Prelude's 2.3L H23A1 or the older 2.1L B21A1 ), it actually represents something entirely different in modern vehicle telemetry.

For vehicles equipped with this system, B23A0-92 points to an EDLC Module Performance Problem or EDLC Module Performance / Stuck Off condition.
The EDLC (Electric Double Layer Capacitor) is used to quickly store and release large amounts of electricity. When this system fails, the vehicle's ability to recover energy via regenerative braking is compromised, often triggering a "Check Charge System" or "Hybrid System" warning light on the dashboard.
