DTC B2788 IG2 Signal Malfunction

DESCRIPTION
The steering lock ECU receives power from the IG2 relay. When the voltage value indicated by the IG signal from the certification ECU equals to the voltage that is applied to the steering lock ECU, the steering will be unlocked. The steering lock ECU will not lock the steering when power from the IG2 relay is present (this prevents the steering from being locked while the vehicle is moving).
