Circuit/System Verification
WARNING: This page is about a different car, the 2014 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Both K36 Inflatable Restraint Sensing and Diagnostic Module and K85 Passenger Presence Module set DTC B0081 but with different symptom 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.
- Verify that DTC B1001 is not set in the K36 Inflatable Restraint Sensing and Diagnostic Module.
- If DTC B1001 is set in the K36 Inflatable Restraint Sensing and Diagnostic Module
Refer to Diagnostic Trouble Code (DTC) List - Vehicle .
- If DTC B1001 is not set in the K36 Inflatable Restraint Sensing and Diagnostic Module
- If DTC B1001 is set in the K36 Inflatable Restraint Sensing and Diagnostic Module
- Verify that DTC B0071, B0074, B0081, B101D, or B101E is not set in the K85 Passenger Presence Module.
- If any of these DTCs are set in the K85 Passenger Presence Module
Refer to Diagnostic Trouble Code (DTC) List - Vehicle .
- If none of these DTCs are set in the K85 Passenger Presence Module
- If any of these DTCs are set in the K85 Passenger Presence Module
- Verify that DTC B0081 symptom byte 3A or 71 is not set in the K36 Inflatable Restraint Sensing and Diagnostic Module.NOTE:
The K36 Inflatable Restraint Sensing and Diagnostic Module sets a DTC B0081 3A when an incorrect K85 Passenger Presence Module is installed.
- If DTC B0081 symptom byte 3A or 71 is set in the K36 Inflatable Restraint Sensing and Diagnostic Module
Replace the K85 Passenger Presence Module.
- If DTC B0081 symptom byte 3A or 71 is not set in the K36 Inflatable Restraint Sensing and Diagnostic Module
- If DTC B0081 symptom byte 3A or 71 is set in the K36 Inflatable Restraint Sensing and Diagnostic Module
- All OK.
