B1332
Diagnostic trouble code B1332 - Driver airbag, interruptionT�:
1. Connect the ISAT Note the diagnostic trouble code and the type of fault. P=permanent fault, I=intermittent fault.
If the fault is permanent: Proceed to point 3.
If the fault is intermittent: Proceed to point 2.
2. The fault is intermittent. Try to provoke the fault when taking measurements during fault diagnosis.
Manipulate connect&s and leads as well as turning the steering wheel while taking measurements.
NOTE: If no fault can be demonstrated during measuring, change the contact roller. The contact roller is the most common cause of intermittent faults.
Proceed to point 3.
3. Switch off the ignition and disconnect the negative battery lead. Undo the bolts securing the steering wheel airbag. Unplug the connector on the rear of the airbag and connect reference resistor 84 71 153 to the connector.
On Cars With Passenger Airbag:
a. Remove the glove compartment and unplug the connector on the underside of the passenger airbag.
b. Plug in reference resistor 84 71 153 to the connector.
Proceed to point 4.
���:
4. Refit the negative battery lead and switch on the ignition. Erase the diagnostic trouble code. Switch off the ignition and switch it back on again. Wait for at least 10 seconds with the ignition on.
Check to see if the diagnostic trouble code returns.
If the diagnostic trouble code returns: Proceed to point 6.
If the diagnostic trouble code does not return:
The fault was in the steering wheel airbag. Conduct an extra test as described in point 5.
5. Switch off the ignition and remove the negative battery lead. Remove the reference resistor from the steering wheel airbag connector and connect the steering wheel airbag.
Refit the negative battery lead and switch on the ignition. Wait for at least 10 seconds with the ignition on.
Check to see if the diagnostic trouble code returns.
If the diagnostic trouble code returns: Switch off the ignition and remove the negative battery lead. Change the steering wheel airbag. Then proceed to point 10.
If the diagnostic trouble code does not return:
Switch off the ignition and remove the negative lead from the battery. Unplug the connector from the airbag and refit the reference resistor. Refit the negative battery lead and the proceed to point 6.
�ґ:
6. Switch off the ignition and unplug the connector from the SRS control module. Check pins 10 and 11 for breaks/bad connections.
Refit the connector and switch on the ignition. Erase the diagnostic trouble code. Switch off the ignition and switch it back on again. Wait for at least 10 seconds with the ignition on. Check to see if the diagnostic trouble code returns.
If the diagnostic trouble code returns: Proceed to point 7.
If the diagnostic trouble code does not return:
The fault was in the SRS connector. Proceed to point 10.
NOTE: If no fault was detected in the connector, the fault may be intermittent. Try to provoke any intermittent fault and see if the SRS lamp lights.
7. Switch off the ignition. Unplug connector H2-52 and check pins and sleeves for breaks and bad connections.
Plug in the connector. Switch on the ignition and erase the diagnostic trouble code. Switch off the ignition and switch it back on again. Wait for at least 10 seconds with the ignition on.
Check to see if the diagnostic trouble code returns.
If the diagnostic trouble code returns: Proceed to point 8.
If the diagnostic trouble code does not return:
The fault was in the connector. Proceed to point 10.
NOTE: If no fault was found in the connector, the fault may be intermittent. Try to provoke any intermittent fault and see if the SRS lamp lights.
��:
8. Switch off the ignition: Unplug connector H2-52 and remove the reference resistor from the steering wheel airbag connector.
Change the contact roller. Plug in the connector and reconnect the reference resistor.
Switch on the ignition and erase the diagnostic trouble code. Switch off the ignition and switch it back on again. Wait for at least 10 seconds with the ignition on.
Check to see if the diagnostic trouble code returns.
If the diagnostic trouble code returns: Proceed to point 9.
If the diagnostic trouble code does not return: The fault was in the contact roller. Proceed to point 10.
9. Switch off the ignition and check the cable assembly by connecting a BOB to the SRS control module connector. Connect an ohmmeter between contacts 10 and 11. The ohmmeter should show 3-4 ohms
If the value is OK: Proceed to point 10.
If the value is incorrect: Investigate the cause and change the cable assembly.
Then proceed to point 10.
�=�:
10. Switch off the ignition and remove the negative lead from the battery.
Remove the reference resistor and plug in all connectors to their original components. Refit the negative battery lead and switch on the ignition.
Erase the diagnostic trouble code. Switch off the ignition and switch it back on again. Wait for at least 10 seconds.
Check to see if the diagnostic trouble code returns.
If the diagnostic trouble code returns: Description of On-Board Diagnostics
If the diagnostic trouble code does not return: Return the car to good order.
