Scan Tool Data
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 neu-
tral 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
Back Up Volt (V): This parameter indicates the capacity of the backup condenser installed to maintain the igni-
tion 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 preten-
sioner 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 initi-
ator circuit.
