DTC B2788: IG2 Signal Malfunction: Description
WARNING: This page is about a different car, the 2012 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
The steering lock ECU determines the on/off status of the engine switch through the IG2 signal circuit.
After receiving an 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 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.
| DTC No. | DTC Detecting Condition | Trouble Area |
|---|---|---|
| B2788 | Different information is obtained from IG2 signal received directly from the IG2 circuit, and from IG2 signal sent via LIN communication for a period of 1 second. |
