SITUATION
A situation may occur where the front passenger seat is not occupied; however, a "fasten seat belt" warning and a front passenger seat air bag deactivation message appears.
If the situation is currently present, sit in the seat and move the seat to a slightly different position. The POL (Passenger Occupancy Light) light should now function correctly.
In some cases, the Air bag Warning Light was illuminated, and the following Advanced Crash Safety Module (ACSM) fault is stored:
- 930A1C - Front passenger seat occupancy detection transmitting fault (moisture)
CAUSE
Any, or all, of the following can contribute to this situation:
| Possible Causes | Coverage | |
|---|---|---|
| A. | Electronic devices (For example, smart phones, laptops, tablets, etc) are connected to the vehicle's USB charging port, or cigarette lighter power as a power supply and then placed on the passenger seat. | N/A |
| B. | The passenger seat is wet/fluid contaminated (e.g., very high humidity, wet clothing, spilled liquids, or rain from open windows/sunroofs). | N/A |
| C. | Insufficient shielding of the seat heater/CIS mat wiring**. | ELW |
| D. | Ground connection for the seat heater/CIS mat is not fully secured | ELW |
Component and Issue-Specific Extended Limited Warranty (ELW)
For the eligible vehicles, BMW of North America, LLC (BMW NA) is extending the limited warranty for the repair 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.
There is no immediate repair required unless the BMW vehicle is currently experiencing this problem.
Customer Notification Letter
Even though this is NOT a Recall, BMW NA is sending VIN-specific customer notification letters.
CORRECTION
Front Passenger's Seat Capacitive Interior Sensor (CIS) Mat
Consultation with the customer whether objects were possibly laid on the front passenger seat, or the seat was subjected to moisture (e.g., from rain through an open window, wet clothes or towel, or the spilling of fluids on the seat cushion surface).
Perform a non-invasive check for moisture/stains on the seat and at the CIS evaluation electronics module electrical connector.
Check the seat CIS mat's ground connection and re-secure it as necessary.
If there are no obvious moisture/stains, the next step is to check the vehicle's installed seat heater/CIS mat sensor part number and its revision index number against a corresponding matrix.
The matrix will help you determine if the installation of the seat CIS mat wiring repair kit is required to address an inadequate shielding condition with the seat occupancy CIS mat's connection wiring.
PROCEDURE
Also review the Repair History (Claims) section below in the WVI to confirm that a prior claim for this wiring repair kit retrofit/installation procedure has not already been submitted and accepted. This would include Repair Code 52 10 90 01 00 claim submissions.
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.
Applicable Option Codes
| G11 | 0456 Comfort seat with memory | 04T7 Massage function, driver/fr. passenger | |
| G11 | 0456 Comfort seat with memory | 0453 Climate-controlled seats, front | 04T7 Massage function, driver/fr. Passenger |
| G12 | Base - Standard Seat/No Code | ||
| G12 | 0456 Comfort seat with memory | ||
| G12 | 0456 Comfort seat with memory | 0453 Climate-controlled seats, front | |
| G12 | 0456 Comfort seat with memory | 0453 Climate-controlled seats, front | 04T7 Massage function, driver/fr. passenger |
| G30 G32 | 481 - Sports seat | ||
| G30 G32 | 0456 Comfort seat with memory | ||
| G30 G32 | 0456 Comfort seat with memory | 0453 Climate-controlled seats, front |
The "Find" function (CTRL - F) can be used in AIR to locate the option codes.
For conditions that are like the situation described above:
- 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.
- 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.
- If moisture is found, dry the mat and clear the fault. Moisture caused by outside influence is a non warranty issue.
- If no moisture is found, proceed to the next steps
Steps # 3 through # 7: To continue, 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 the installation of the seat CIS mat wiring repair kit is required.
If the seat mat part number is not listed in the attachment Matrix, then do not install the repair harness.
- B720125_AT_1 Repair Procedure 06_2025
8. If the false passenger seat occupancy alert cannot be corrected by applying steps # 1 through # 7, including when the matrix information does not apply to the installed seat mat sensor, then proceed again as follows, ensure:
- There are external no punctures through the seat cover material and the seat mat sensor
- The seat mat sensor has no hog rings installed through it
- The seat mat sensor is not folded over, onto itself
- The passenger seat cover is not installed overly taut, putting pressure on the seat mat sensor when no-one is in the seat
When none of the above applies, then replace the seat mat sensor avoiding the issues above.
