For the eligible vehicles, BMW of North America, LLC (BMW NA) is extending the limited warranty for the repair
to address the issue described in this Service Information Bulletin to:
10 years/120,000 miles as determined from the vehicles original first in-service / delivery date
This component and issue-specific limited warranty extension applies to defects in materials or workmanship.
This coverage applies to the specific vehicle (VIN), the remaining portion of the ELW is transferrable to each
subsequent owner, and it is subject to the same vehicle eligibility requirements, limitations, and exclusion
criteria that applies to the BMW New Vehicle Limited Warranty for Passenger Cars and Light Trucks.
Note: This bulletin is notice of a limited warranty extension. This is NOT a notice of a Recall or Service
Action.

If there are no obvious moisture/stains, the next step is to then check the vehicle’s installed seat heater/CIS
sensor mat part number and its revision index number against a corresponding matrix.
The matrix will help you determine if a seat CIS mat replacement is required to address an inadequate shielding
condition with the seat occupancy sensor’s connection wiring.

Note: Replacing the CIS electronics and / or
the ACSM module will not correct this issue.

PROCEDURE
Use AIR to identity the vehicle’s installed seat option, and to determine if there are also any optional seat
accessories installed, this information is required other steps later in the procedure.

For conditions that are like the situation described above:
1. Verify with the customer that no objects were lying on the seat that could have caused the warnings.
Note: Electronic devices that are placed on the front passenger seat, e.g., laptop computers, mobile phones, etc., could
cause the front passenger airbag warning lamp to activate

This behavior occurs primarily with devices that are connected to the vehicle electrical system via a USB cable or other
charger adapter.
In vehicles with an acoustic safety belt warning, this could cause the warning signal to sound.
2. Moisture on the seat surface can also cause a faulty seat occupancy detection. In this case ACSM fault 930A1C will
be stored.
Perform a non-invasive check for signs of moisture.
a. If moisture is found, dry the mat and clear the fault. Moisture caused by outside influence is a non-warranty
issue.
b. If no moisture is found, proceed to the next steps
To continue to Step # 3, refer to the attachment for information on checking the seat heater/CIS mat’s ground
connection and the installed part number, and its revision index number against a corresponding matrix, this will help
you determine if a CIS mat replacement is necessary.
