4. Check that the passenger seat belt reminder light is on (illuminated).

> If the passenger seat belt reminder light is illuminated, go to step 5.

> If the passenger seat belt reminder light does not illuminate, DTC B1312 is not the cause of the "AIRBAG" warning light. Refer to the Suzuki Service Manual to determine the DTC stored and diagnose the issue.

Codes other than a Current B1312 are not eligible for this special coverage extension. If the vehicle is still within the 3/36 basic warranty period, repair it according to normal policies & procedures.
