(2)After erasing the diagnosis code memory, check the diagnosis code again. (1)Connect the negative battery terminal. Check whether the diagnosis code is reset. Repair the CAN bus line (Refer to GROUP 54C - Troubleshooting ). Use M.U.T.-III to diagnose the CAN bus lines.

Open circuit to side-airbag module (squib) circuit.

The code is set when the open circuit occurs to the SRS-ECU side-airbag module (squib) circuit. In case of side collision, when the impact exceeding the threshold is applied to the vehicle, and when the impact is simultaneously detected (turned ON) by the side impact sensor as well as by the analogue G-sensor in SRS-ECU, the electric current is supplied from SRS-ECU to the side-airbag module (squib) of impacted side. If the diagnosis code B1C29 is set to SRS-ECU, be sure to diagnose the CAN bus line.
