Circuit/System Verification
Use the table below in identifying specific module DTC B0081 application and symptom byte that sets with it.
| DTC | Symptom Bytes | |
|---|---|---|
| B0081 - Inflatable Restraint Sensing and Diagnostic Module | 00 | 3A |
| B0081 - Passenger Presence Module | 11 | 4B |
NOTE:
- This system is serviced as a kit (seat foam, module and sensing mat). Perform a passenger presence system preload procedure whenever a component is replaced. Refer to Passenger Presence System Programming and Setup .
- Both Inflatable Restraint Sensing and Diagnostic Module and Passenger Presence Module set DTC B0081 but with different symptoms bytes. Therefore it is important to identify which module has set the DTC B0081. Use the symptom bytes as a way of identify the correct module to diagnose.
- The Inflatable Restraint Sensing and Diagnostic Module sets a B0081 3A when an incorrect Passenger Presence Module is installed.
- Verify that DTC B0081 3A is not set in the Inflatable Restraint Sensing and Diagnostic Module.
- If DTC B0081 3A is set in the Inflatable Restraint Sensing and Diagnostic Module
Replace the K85 Passenger Presence Module.
- If DTC B0081 3A is not set in the Inflatable Restraint Sensing and Diagnostic Module
- If DTC B0081 3A is set in the Inflatable Restraint Sensing and Diagnostic Module
- Verify that DTC B0081 11 or DTC B0081 4B is not set in the Passenger Presence Module.
- If DTC B0081 11 or DTC B0081 4B is set in the Passenger Presence Module
Perform the passenger presence system rezero procedure. Refer to Passenger Presence System Programming and Setup .
- If DTC B0081 11 or DTC B0081 4B is not set in the Passenger Presence Module
- If DTC B0081 11 or DTC B0081 4B is set in the Passenger Presence Module
- All OK.
NOTE:
The Inflatable Restraint Sensing and Diagnostic Module sets a B0081 00 DTC when the Passenger Presence Module sets a DTC B0081 11 or B0081 4B.
