Subaru Crosstrek Service Manual: Dtc b1832 short in curtain airbag rh squib circuit (to ground)

Diagnosis start condition:

Ignition voltage is 10 V to 16 V.

DTC detecting condition:

• Curtain airbag harness (RH) circuit is shorted to ground.

• Curtain airbag module (RH) is faulty.

• Airbag control module is faulty.

Before performing diagnosis, refer to “CAUTION” in “General Description”. General Description > CAUTION">

1.CHECK POOR CONTACT OF CONNECTORS.

Check for poor contact of the connectors between the airbag control module, curtain airbag module RH and the curtain airbag sensor RH.

Is there poor contact?

Replace the airbag rear harness along with body harness.

2.CHECK CURTAIN AIRBAG MODULE.

1) Turn the ignition switch to OFF, disconnect the battery ground cable, and wait for 60 seconds or more.

2) Disconnect the connector (AB33), and connect the connector (1N) in test harness N to connector (AB33).

3) Connect the airbag resistor to the connector (2N) of test harness N.

4) Connect the battery ground terminal and turn the ignition switch to ON.

Does the airbag warning light illuminate for six seconds and go off?

3.CHECK AIRBAG REAR HARNESS (CURTAIN AIRBAG MODULE HARNESS RH).

1) Turn the ignition switch to OFF, disconnect the battery ground cable, and wait for 60 seconds or more.

2) Disconnect the connector (AB26) from seat belt pretensioner (RH).

3) Disconnect connector (AB24) from side airbag module (RH).

4) Disconnect the airbag resistor from test harness N.

5) Disconnect the connectors (AB6, AB17, AB18) from airbag control module.

6) Connect the connector (1AG) in the test harness AG to the connectors (AB6, AB17, AB18).

7) Measure the resistance between connector (6AG) in the test harness AG and chassis ground.
