Front occupant classification sensor rh collision detection
Description
Dtc b1786 is output when the occupant classification ecu receives a collision
detection signal sent by
the front occupant classification sensor rh when an accident occurs.
Dtc b1786 is also output when the front seat assembly rh is subjected to a
strong impact, even if an
a ...
Terminals of ecu
Check power steering ecu
Hint:
Measurements cannot be performed on the c connector
side of the power steering ecu.
Measure the voltage and resistance of the
connectors.
If the result is not as specified, the ecu may have a
malfunction. ...
