DTC B2782 Power Source Control ECU Malfunction
for Preparation Click here
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 intelligent tester via the certification ECU (smart key ECU assembly) as the
steering lock ECU is not connected to the CAN communication system.
