Scan Tool Data
S3RH0A8204032
As the data values given below are standard values
estimated on basis of obtained from the normally
operating vehicle by using a scan tool, use them as
reference value.
NOTE
When checking the data with the engine
running at idle or racing, be sure to shift M/T
gear to the neutral gear position and A/T gear
to the “Park” position and pull the parking
brake fully. Also, if nothing or “no load” is
indicated, turn OFF A/C, all electric loads and
all the other necessary switches.
Scan Tool Data Definition
S3RH0A8204033
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 Voltage (V): Battery voltage is an analog input
signal read by the SDM.
System ID (4 ch / 6 ch): This parameter indicates the
number of initiator circuits.
Driv Air Bag Ini Res (OHMS (
Ω
)): This parameter
indicates the resistance of the driver’s air bag initiator
circuit.
Pass Air Bag Ini Res (OHMS (
Ω
)): This parameter
indicates the resistance of the passenger’s air bag
initiator circuit.
Driv Preten Ini Res (OHMS (
Ω
)): This parameter
indicates the resistance of the driver’s seat belt
pretensioner initiator circuit.
Pass Preten Ini Res (OHMS (
Ω
)): This parameter
indicates the resistance of the passenger’s seat belt
pretensioner initiator circuit.
Driv Sidebag Ini Res (OHMS (
Ω
)): This parameter
indicates the resistance of the driver’s side air bag
initiator circuit.
Pass Sidebag Ini Res (OHMS (
Ω
)): This parameter
indicates the resistance of the passenger’s side air bag
initiator circuit.
