DTC B2782 Power Source Control ECU Malfunction: Description

The steering lock ECU activates the steering lock motor by the power from the main body ECU through the IGE circuit. This prevents the steering from being locked while the vehicle is moving. The diagnosis information of the steering lock ECU is transmitted to the Techstream via the certification ECU as the steering lock ECU is not connected to the CAN communication system.
