* 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.
