* Driver steering wheel air bag coil connector Stage 2 terminal A X2 and SDM terminal 1 X1.

瀚慖f greater than the specified range, test the circuit for an open/high resistance.

16. Test for less then 1 ohm between the SDM connector and the air bag connector low circuit terminals listed below.

* Driver steering wheel air bag coil connector Stage 1 terminal B X1 and SDM terminal 3 X1

* Driver steering wheel air bag coil connector Stage 2 terminal B X2 and SDM terminal 2 X1

瀚慖f greater than the specified range, test the circuit for an open/high resistance.

17. If all circuits test normal, replace the SDM.
