If there are no obvious moisture/stains, the next step is to then check the vehicle’s installed seat heater/CIS
seat mat sensor part number and its revision index number against a corresponding matrix.
The matrix will help you center 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, and/or,
A CIS mat sensor replacement is necessary because it was inadvertently pierced by unfavorably
positioning of the crimp rings that secure the seat cover in place.

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

Note: Before performing this seat heating wiring repair kit retrofit/installation procedure and submitting
a claim, first confirm that the vehicle has one of the above coverage notices in the Warranty Vehicle
Inquiry’s (WVI) Vehicle Comments section.
Also review the Repair History (Claims) section below in the WVI to confirm that a prior claim for this

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 nonwarranty 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 sensor’s
ground connection and the installed part number, and its revision index number against a corresponding matrix.
This will help you determine if:
Applicable G01/G02 - Installation of the seat CIS mat wiring repair kit is required and/or replace the seat CIS
mat.
Or, for the :
