Data list of SDM
Scan Tool Data Definition
Back Up Volt (V): This parameter indicates the
capacity of the backup condenser installed to
maintain the ignition current (as much as possible)
even when the power supply to SDM that ignites the
inflator is shut off.
Battery Volt (V): Battery voltage is an analog input
signal read by SDM.
System ID (4ch/8ch): This parameter indicates the
number of initiator circuits.
Driv A/B Ini Res (Driver air bag initiator resistance)
(ohm): This parameter indicates the resistance of
the driver air bag initiator circuit.
Pass A/B Ini Res (Passenger air bag initiator
resistance) (ohm): This parameter indicates the
resistance of the passenger air bag initiator circuit.
Driv Pret Ini Res (Driver pretensioner initiator
resistance) (ohm): This parameter indicates the
resistance of the driver seat belt pretensioner
initiator circuit.
Pass Pret Ini Res (Passenger pretensioner initiator
resistance) (ohm): This parameter indicates the
resistance of the passenger seat belt pretensioner
initiator circuit.
LH Side Ini Res (Left side-air bag initiator resistance)
(ohm): This parameter indicates the resistance of
the left side-air bag initiator circuit.
RH Side Ini Res (Right side-air bag initiator
resistance) (ohm): This parameter indicates the
resistance of the right side-air bag initiator circuit.
LH Curtain Ini Res (Left side curtain-air bag initiator
resistance) (ohm): This parameter indicates the
resistance of the left side curtain-air bag initiator
circuit.
RH Curtain Ini Res (Right side curtain-air bag
initiator resistance) (ohm): This parameter
indicates the resistance of the right side curtain-air
bag initiator circuit.
