DTC B2788: IG2 Signal Malfunction: Description

The steering lock ECU determines the on (IG)/off status of the engine switch through the IG2 signal circuit.

After receiving an integration relay (IG2 relay) on signal, the steering lock ECU determines that the vehicle is moving.

The steering lock ECU does not lock the steering when it receives the integration relay (IG2 relay) on signal. 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.
