Circuit/System Verification

Note:

* This system is serviced as a kit (seat foam, module and/or sensing mat). Perform a Passenger Presence System Preload procedure whenever a

component is replaced. Refer to Passenger Presence System Preload Test (See: Restraints and Safety Systems/Air Bag Systems/Description

and Operation/Passenger Presence System Preload Test).

* Both SDM and 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.

1. Verify that DTC B1001 is not set in the SDM.

瀚慖f the DTC is set in the SDM, refer to DTC B1001 (See: B Code Charts/B1001/Supplemental Inflatable Restraints).

2. Verify that DTC B0074, B101D, or B101E is not set in the passenger presence module.

瀚慖f any of the DTCs are set in the passenger presence module, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic

Trouble Code Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle).

Note: The SDM sets a redundant B0081 00 DTC when the passenger presence module sets a DTC B0081 11 or B0081 4B.

3. Verify that DTC B0081 00 is not set in the SDM

瀚慖f DTC B0081 00 is set in the SDM, then the passenger presence module has set a B0081 11 or a B0081 4B. Refer to B0081 (Passenger

Presence Module) for diagnosis.

Note: The SDM sets a B0081 3A when an incorrect passenger presence module is installed.

4. Verify that DTC B0081 3A is not set in the SDM.

瀚慖f DTC B0081 3A is set in the SDM, replace the K85 passenger presence module.

Repair Instructions

Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
