Conditions to Activate Seat Belt Light

When the passive restraint module determines a seat belt warning is required, the fasten seat belt indicator output (pin 1M), supplies a ground to the Fasten Belt Indicator (FBI). This action activates the seat belt light.

When the ignition key is in the ON position (pin 2C high), and both of the B-pillar limit switches are not activated (pin 1E or 2O floating /not grounded), the FBI output is activated (pin 1M grounded).

The FBI is also activated when the ignition key is in the ON position (pin 2C high), and either of the shoulder belts are spooled in (pin 2B or 1O floating/not-grounded).

WARNING
THE WARNING CHIME MODULE INTERFACES WITH THE WARNING LIGHT.
