* Control circuit terminal A1
* Control circuit terminal A2
* Control circuit terminal B1
* Control circuit terminal B2
锟斤拷 If less than the specified range, test the control circuit for a short to ground.
11. Ignition OFF, test for less than 5 ohm between the control circuit terminals listed below:
* X200 control circuit terminal A1 and passenger instrument panel air bag harness connector control circuit terminal A1
* X200 control circuit terminal A2 and passenger instrument panel air bag harness connector control circuit terminal A2
* X200 control circuit terminal B1 and passenger instrument panel air bag harness connector control circuit terminal B1
* X200 control circuit terminal B2 andpassenger instrument panel air bag harness connector control circuit terminal B2
锟斤拷 If greater than the specified range, test the control circuit for an open/high resistance.
12. If all circuits test normal, replace the passenger instrument panel air bag.
