Circuit/System Verification
WARNING: This page is about a different car, the 2010 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
This system allows you to service each component separately (module and/or sensing mat). Perform a passenger presence detection system rezero procedure whenever a component is replaced.
NOTE:
Both SDM and passenger presence detection 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. Use the table below in identifying specific module DTC B0081 application and symptom byte that sets with it.
| DTC | Symptom Bytes | |
|---|---|---|
| B0081 - SDM | 00 | 3A |
| B0081 - Passenger Presence Detection Module | 11 | 42 |
NOTE:
The SDM sets a B0081 3A when an incorrect passenger presence detection module is installed.
- Verify that DTC B0081 3A is not set in the SDM.
- If DTC B0081 3A is set in the SDM, replace the K85 passenger presence detection module.
- Verify that DTC B0081 11 or DTC B0081 42 is not set in the passenger presence detection module.
- If DTC B0081 11 or DTC B0081 42 is set in the passenger presence detection module, perform the passenger presence detection system rezero procedure. Refer to Passenger Presence System Rezeroing .
NOTE:
The SDM sets a redundant B0081 00 DTC when the passenger presence detection module sets a DTC B0081 11 or B0081 42.
