DTC B1015 : Passenger Air Bag Initiator Circuit Resistance High
Step
1 1) With ignition switch OFF, disconnect passenger air
bag (inflator) module connector "G74" behind the
glove box.
2) Check proper connection to passenger air bag (infla-
tor) module at terminals in "G74" connector.
3) If OK, then connect Special Tool (B) to passenger air

at the step 1).
With ignition switch ON, is DTC B1015 current?
2 1) With ignition switch OFF, disconnect SDM connector
"G66".
2) Check proper connection to SDM connector "G66" at
terminals "G66-24" and "G66-23".
3) If OK, release shorting bar in SDM connector insert-
ing release tool (1) included in special tool (A).
4) Measure resistance between "G66-24" and "G66-23"
terminals with Special Tool (B) connected to "G74"
connector.
Is resistance 3.8 Ω or less?
