Summary
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)
The “Find” function (CTRL – F) can be used in AIR to locate the option codes.
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.

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.

heater/CIS mat’s ground
connection and the installed part number, and its revision index number against a corresponding matrix, this will
