DTC B2782: Power Source Control ECU Malfunction: Description

• The steering lock ECU (steering lock actuator assembly) activates the steering lock motor by the power from the power management control ECU through the IGE circuit. This prevents the steering wheel from being locked while the vehicle is moving.
• If NG (Past) is displayed for Power Supply Open in the Data List, perform troubleshooting according to the procedures below.

The diagnosis information of the steering lock ECU (steering lock actuator assembly) is transmitted to the Techstream via the certification ECU (smart key ECU assembly) as the steering lock ECU (steering lock actuator assembly) is not connected to the CAN communication system.
