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. Code No.B1C29 Left side-airbag module (squib) system (open circuit of squib circuit) Code No.B1C29 Left side-airbag module (squib) system (open circuit of squib circuit)
