- turn the ignition switch to on.
- for the connector (on the seat belt pretensioner side) between
the airbag sensor assy center and the seat belt pretensioner
(rh), measure the voltage between pr+ and
body ground.
Ok: voltage: below 1v

4 Use simulation method to check
Replace all srs components including the wire harness
Other materials:
Automatic air conditioning system
Air outlets are automatically selected and fan speed is automatically
adjusted according to the set temperature setting.
Also, the display and button positions will differ depending on
the type of the system.

Inspection procedure
Hint:
when the throttle position is slightly opened (the accelerator pedal
is slightly depressed) because a
floor carpet is overlapped on the accelerator pedal, or if not fully
releasing the accelerator pedal, etc.,
Dtc p505 will possibly be detected.
Read freeze frame data using the ...
