The SRS-ECU judges how severe a collision is by detecting signals from the left and right side impact sensors. If the impact is over a predetermined level, the SRS-ECU sends an ignition signal. At this time, if the side-airbag safing G-sensor is on, the SRS side-airbag will inflate.
The ignition signal is input to the side-airbag module to inflate the side-airbag.

Short circuit between the side-airbag module (LH) (squib) circuit terminals
Malfunction of the SRS-ECU
STEP 1. M.U.T.-III CAN bus diagnostics
Is the CAN bus line found to be normal?
STEP 2. Check whether the diagnosis code is reset.
