How to proceed with troubleshooting
Hint:
carry out troubleshooting in accordance with the procedures on the following
page. Here, only the basic
procedures are shown. Details are provided in the diagnostics section, showing
the most effective methods
for each circuit. Confirm the troubleshooting procedures first for the releva ...
Circuit description
The side squib (lh) circuit consists of the airbag sensor assy center and
front seat airbag assy (lh).
It causes the srs to deploy when the srs deployment conditions are satisfied.
Dtc b0115/47 is recorded when a short is detected in the side squib (lh)
circuit.

LTA (Lane Tracing Assist)
LTA functions
When driving on a road with
clear lane lines with the
dynamic radar cruise control
operating, lane lines and preceding
and surrounding vehicles
are detected using the
front camera and radar sensor,
and the steering wheel is
operated to maintain the vehicle's
