Circuit description
This diagnosis code is output when the steering lock actuator ASSY (Steering lock ECM) detects an IG2 power supply malfunction.
As the steering lock actuator ASSY (Steering lock ECM) is not connected to CAN communication, CAN communication with external parts is performed via the LIN communication-connected smart key computer ASSY (Collation ECM).
| Diagnostic codes | Detecting conditions | Faulty part | Diagnostic code output check operation | ||
|---|---|---|---|---|---|
| B2788 | When a mismatch occurs between the IGN2 input of the steering lock ECM, and both the LIN communication line input and solid line input. (1 trip detection (1)) |
|
No output verification required (constantly detected) | ||
