PRODUCT Vehicle Data Recorder and Seat Belt Warning system BY AMS
5.5. Seat Belt Warning input module (p/n 118093)
The Seat Belt Warning input module (p/n 118093) monitors the status of 10
seats and 10 seat belts for use in determining seat and seat belt status and
transmitting the results to the Seat Belt Warning display and Vehicle Data
Recorder.
The Seat Belt Warning input module transmits four ES-Key network tags based
on seat and seat belt combinations that may be used within an ES-Key network
database for alarm purposes.
5.5.1. Network alarm tags
The Seat Belt Warning input module is recognized as an input module within the ES-Key network database. The
address is determined by the Seat Belt Warning input module’s address jumper position (see section 4.2.4). The
address is 14 when the jumper is in position 1, and 15 when the jumper is in position 2.
INPUT
SPACE
CONDITION DESCRIPTION
24 Buckled but occupant is leaning
This input is ACTIVE when a seat position was occupied and buckled
correctly, but currently the seat switch is not activated.
25 Seat belt violation
This input is ACTIVE when a seat is occupied BUT the associated seat belt
is NOT buckled.
26 Buckled and not occupied
This input is ACTIVE when a seat belt is buckled BUT the associated seat
is not occupied.
27 Sequence violation
This input is ACTIVE when a seat belt is buckled and THEN the associated
seat is occupied.
5.5.2. Diagnostic LEDs
The Seat Belt Warning input module has 3 LEDs which are
intended for quick diagnostic evaluation and are viewable through
the amber enclosure.
PWR – red LED is ON when the VDR module has proper voltage
after the internal fuse.
BUS – yellow LED is on when the VDR module has proper
voltage at the gray connector (power stud, and pin 12 –
see section 9.1).
COM – green LED is ON solid when CAN communication is
good with a Seat Belt Warning display.
The CAN communication LED (COM) will flash to indicate an error.

Slow flash (once per second) indicates that the CAN bus is good but the Seat Belt Warning input module
is not receiving messages from the Seat Belt Warning display.

Fast flash (five times per second) indicates that there is a passive CAN bus communication error. Verify
that terminating resistor(s) are installed, verify the connection to the CAN bus is properly connected, etc.

Double flash (every two seconds) indicates that there is an active CAN bus communication error. Verify
that CAN H and CAN L are not shorted together or to ground or power, etc.
