Fasten Safety Belt Indicator

The IPC illuminates the fasten safety belt indicator when the following occurs:
^ The inflatable restraint Sensing and Diagnostic Module (SDM) detects that the driver's seat belt is unbuckled. The PC receives a class 2 message from the SDM requesting illumination. The IPC illuminates the indicator for 20 seconds and then flashes the indicator for 55 seconds. The IPC also sends a class 2 message to the radio in order to activate the audible warning.
^ The IPC performs the bulb check.
^ The IPC detects a loss of class 2 communications with the SDM.
