* Driver seat side airbag terminal 1 and 2
* Passenger seat side airbag terminal 1 and 2
* Driver seat belt retractor pretensioner terminal 1 and 2
* Passenger seat belt retractor pretensioner terminal 1 and 2
7. Verify the scan tool Deployment Loop Resistance parameter is less than 2 ohm.
瀚慖f greater than the specified range, test both control circuits terminals for an open/high resistance. If the circuits test normal, replace the
SDM.
8. If all circuits test normal, replace the roof rail air bag, seat side air bag, or seat belt pretensioner.
DTC B0019-B0020
1. Ignition OFF, disconnect the scan tool and disconnect harness connector X200.
2. Wait for 120 seconds and then test for greater than 25 ohm between the appropriate control circuit terminals listed below on the SDM side of
the connector:
* Passenger instrument panel airbag stage 1 terminal 5 and 6 X1
* Passenger instrument panel airbag stage 2 terminal 8 and 7 X1
瀚慖f less than the specified range, test for a short between the control circuits, check each connector and CPA to ensure that the shorting
bars are lifted. If the circuits and shorting bars tests normal, replace the SDM.
3. Ignition ON, test for less than 11 V between the control circuit terminals listed below and ground on the SDM side of the connector:
* Control circuit terminal 5 X1
* Control circuit terminal 6 X1
* Control circuit terminal 8 X1
* Control circuit terminal 7 X1
瀚慖f greater than the specified range, test the control circuit for a short to voltage. If the circuit tests normal, replace the SDM.
4. Ignition OFF, test for greater than 25 ohm between the control circuit terminals listed below and ground on the SDM side of the connector:
* Control circuit terminal 5 X1
* Control circuit terminal 6 X1
* Control circuit terminal 7 X1
* Control circuit terminal 8 X1
瀚慖f less than the specified range, test the control circuit for a short to ground. If the circuit tests normal, replace the SDM.
5. Install a 3 A fused jumper wire between the control circuit terminals listed below.
* Passenger instrument panel airbag stage 1 terminal 5 and 6 X1
* Passenger instrument panel airbag stage 2 terminal 8 and 7 X1
6. Verify the scan tool Deployment Loop Resistance parameter is less than 2 ohm.
瀚慖f greater than the specified range, test both control circuits terminals for an open/high resistance. If the circuits test normal, replace the
SDM.
7. Disconnect the passenger instrument panel air bag harness connector.
8. With the appropriate load tool adaptor, connect special tool J 38715-A in place of the air bag.
9. Ignition ON, test for less than 11 V between the control circuit terminals listed below and ground:
* Control circuit terminal A1
* Control circuit terminal A2
* Control circuit terminal B1
* Control circuit terminal B2
瀚慖f greater than the specified range, test the control circuit for a short to voltage.
10. Ignition OFF, test for greater than 25 ohm between the control circuit terminals listed below and ground:
* Control circuit terminal A1
* Control circuit terminal A2
* Control circuit terminal B1
* Control circuit terminal B2
瀚慖f less than the specified range, test the control circuit for a short to ground.
